the vsns pin takes the role of the ref input of the tl431 ? the opto pin takes the role of the cathode ? the gnd pin takes the role of the anode in addition to the constant voltage (cv) mode, which is regulated via the vsns pin, the system supports constant current (cc) mode. the current control loop is regulated and the cable compensation is added via the isns pin. alternatively, the isns input can be used for overcurrent protection (ocp; see table 4 ). several other protections are available. many of these protections are programmable as latched or safe restart. for guaranteed safety, all protections are implemented in hardware. so, even when the microcontroller stops, the protections are still functional. the output voltage and the output current can be controlled via usb-pd using the cc pins. they can also be controlled via qc using the dp and dm pins. the output current and the output voltage are continuously measured via an integrated ad-converter. the values can be made available continuously via the usb-pd protocol. the applied time constant of the digital filter is initialized via the firmware. a dedicated signal that indicates a stable output voltage/output current for a reliable measurement is available. it can be used, for example, to determine and monitor the cable resistance in the portable device. the external temperatures, measured via the gpio1 and gpio2 pins, are continuously monitored. from the gpio voltages and applied currents, the controller calculates the corresponding temperatures. these temperatures can be communicated to the portable device. optionally, an otp function is added to this external temperature measurement, which is programmable via mtp (see table 4 ). the available protections are implemented in hardware. they are independent of processor actions. these protections in combination with the nmos load switch ensure a fully safe operation with only one optocoupler. when the optocoupler fails, the ovp of the primary side controller (tea1936x) limits the maximum output voltage. the tea19051btk fully supports the type-c connector standard. when a type c receptacle is used, the cc1/cc2 pair is used for plug attach/detach detection. it is also meant to support the usb-pd communication standard. the dp/dm pair is meant to support: ? battery charging 1.2 ? qualcomm ? quickcharge ? qc2.0 and qc3.0 the usb-pd specification requires the use of a load switch and certain discharge behavior of the output voltage at the connector v bus . so, to drive the gate of an external nmos switch, the tea19051btk is equipped with an sw pin. to be able to discharge v bus using an external resistor in series with an internal switch, the tea19051btk is equipped with a disch pin. user-defined parameters can be stored in the non-volatile multi-time programmable (mtp) memory. nxp semiconductors tea19051btk usb-pd 2.0/usb-pd 3.0/qc 2.0/qc 3.0/qc 4 (+) controller for smps tea19051btk all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2018. all rights reserved. product data sheet rev. 2 27 august 2018 8 / 54 8.1 start-up and supply the tea19051btk is supplied via the vcc pin connected to the secondary dc voltage of an ac-to-dc smps converter (see figure 7 ). to control the primary side controller, this vcc voltage is regulated via an integrated voltage/current control loop with external loop compensation and an external optocoupler. this optocoupler is part of the gain loop of the primary side smps controller. at each start-up and after power-on reset, the optocoupler current is initially zero. so, the ac-to-dc converter starts up with full output power, resulting in a rapid increase of the vcc voltage. due to the low v cc(start) level (3 v), the tea19051btk ensures that it is fully operating before the v cc reaches the default initial regulation level. the default values of the initial regulation level are 5 v and 3 a and they are programmed in the non- volatile memory (mtp). at power-on reset, the safe default values, which are read from mtp, are set. when the v cc voltage is below the uvlo level, the external nmos load switch is off. when the output is shorted while the load switch is closed, the uvlo is also triggered. the load switch is then immediately opened and the system restarts after the safe restart timer. when the v cc exceeds the uvlo level, all circuits, the initial dac value, and the resistive divider ratio are initialized. the system regulates the output to 5 v with a limited output current of 3 a. all these values can be set via the mtp. to minimize the output voltage overshoot after start-up, an internal 20 ma current sink is applied to vcc when the vcc voltage exceeds 1.05 v o(default) . the sink current remains active until the vcc voltage has dropped to below 1.05 v o(default) again. after the output voltage has stabilized, the load switch becomes conducting and the system waits for an attach. before the attach, only the essential circuits are working which reduces the no-load power to its minimum. when the voltage on one of the cc pins drops to below the v ih(rd) level, an attach is detected and all circuits are enabled. if a protocol is detected, it is allowed to change the voltage and current. 5 v regulation 20 ma discharge v c c reading eeprom initialization 1.05 x v o(default) uvlo aaa-023848 figure 3.?start-up sequence the tea19051btk operates on supply voltages up to 21 v. the voltage on the vcc pin is used to detect an ovp and uvp. the ovp and uvp level are set as a percentage of the requested output voltage level. nxp semiconductors tea19051btk usb-pd 2.0/usb-pd 3.0/qc 2.0/qc 3.0/qc 4 (+) controller for smps tea19051btk all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2018. all rights reserved. product data sheet rev. 2 27 august 2018 9 / 54 if the supply voltage drops to below the uvlo level, the system returns to the no-supply state and opens the load switch. analog circuits are reset below uvlo. the internal digital circuits are reset below the band gap voltage reference level. 8.2 voltage loop the analog constant voltage (cv) loop regulates vcc such that the voltage on the vsns pin equals the internal reference voltage. an external resistor divider is connected between vcc, the vsns pin, and ground. the value of this divider must match the value that is programmed in mtp exactly. it depends on the maximum voltage in the application. the divider values are: ? 1/ 2.5; maximum pdo voltage 6 v ? 1/5.476; maximum pdo voltage 13 v ? 1/8.325; maximum pdo voltage 20 v ? 1/8.828; maximum pdo voltage 21 v the cv loop is regulated by varying the current through an optocoupler diode similar to a tl431 driven control loop commonly used in switch mode power supplies. the rc combination between the opto and vsns pin determines the dynamic behavior of the integrating part of the control loop. the resistor in series with the optocoupler diode determines the dynamic behavior of the proportional part of the control loop. to prevent saturation of the control loop during switching, a diode is placed in parallel to this resistor. see section 13.3 for more information about the control loop. when the voltage loop reference is set to a higher value using the usb-pd or the qc protocol, the internal reference voltage is updated to the new setting within 20 s. the output voltage is regulated to the requested voltage with a speed determined by the control loop. if there is a transition down, a predefined ramp down sequence is followed to prevent a high undershoot. depending on the step size, the ramp down either follows a linear or a parabolic slope. for a transition up, no special measures are required to prevent an overshoot. the reason is that the charging current of the loop capacitor lifts the voltage on the vsns pin when the v cc voltage in the application increases. nxp semiconductors tea19051btk usb-pd 2.0/usb-pd 3.0/qc 2.0/qc 3.0/qc 4 (+) controller for smps tea19051btk all information provided in this document is subject to legal disclaimers. ?

nxp b.v. 2018. all rights reserved. product data sheet rev. 2 27 august 2018 12 / 54 8.4 cable compensation with cable compensation enabled, the output voltage is increased when the output current increases to compensate for the voltage drop over the cable. the value of the cable compensation is the same for all pdos. it is set in mtp between the minimum and maximum values (see table 4 ). setting the cable compensation above 200 mv/a is not recommendable. the cable compensation can be enabled/disabled for each individual pdo. 8.5 load switch a low-cost nmos transistor is used as load switch between v cc and v bus (see figure 7 ). a dedicated switch-drive output pin (sw pin) controls this nmos transistor. the output (high) level of the switch drive output is v cc + 6 v using an internal charge pump. as long as v cc is below the uvlo level or if the vcc connection is open, the sw pin is held low, ensuring that the load switch is off. to ensure that the nmos is also kept off when the sw pin is disconnected, an external (high-ohmic) resistor is required between the gate of the nmos and v bus . to avoid charging v cc via the back-gate diode of the load switch, it is possible to apply two nmos switches in series, with their sources connected together. 8.6 discharge function the disch pin, which has an internal low-ohmic switch, provides the means to discharge the output v bus quickly. an external series resistor limits the maximum current and the ic dissipation. to check if the output voltage has dropped to below 0.8 v, a comparator is implemented. this voltage drop is a requirement of the usb-pd specification (vsafe0v) if there is a hard reset. when the internal disch switch is activated, the voltage at the disch pin is always low, because of the external current limiting resistor. a mechanism has been implemented to check the real output voltage. during a hard reset discharge sequence, when v cc is below vsafe5v, the switch is opened every millisecond for 20 s to check the output voltage at the end of the 20 s period. the check of the output voltage is done until the voltage remains below 0.7 v and the hard reset discharge sequence is terminated. for this check to work properly, the capacitance on the disch pin and the external current limiting resistor must have a time constant that is short enough. nxp semiconductors tea19051btk usb-pd 2.0/usb-pd 3.0/qc 2.0/qc 3.0/qc 4 (+) controller for smps tea19051btk all information provided in this document is subject to legal disclaimers. ? nxp b.v. 2018. all rights reserved. product data sheet rev. 2 27 august 2018 13 / 54 to ensure that the output remains low, a 1 ma sink current is present on the disch pin when both the load switch and discharge switch are off. the period that the disch pin is active in unattached state (t d(act) ) is typically 100 ms. the reason for this limitation is to prevent that excessive power dissipation occurs if an external v bus voltage is applied. 8.7 detach detection when the voltage on one of the cc pins is greater than 1.2 v, a detach is detected. if the type c cable is disconnected, the output voltage is regulated to its default value (5 v) after 200 s. 8.8 internal temperature measurement the internal die temperature is monitored continuously. its value can be requested with the appropriate vendor defined message (vdm). when the internal otp (see table 5 ) is enabled, the internal otp is triggered when the die temperature exceeds the value that is programmed in mtp. 8.9 gpio pins the internal hardware of the gpio1 and gpio2 pins is identical. in the mtp, the following functions can be selected for each gpio pin: ?

the supply signal is high continuously ? dynamic switching of the i 2 c slave supply on the gpio pin. when the master activates i 2 c communication, the supply is turned on first. after a delay, the i 2 c communications start. when i 2 c communications stops for 1 s, the supply is turned off. ?

change the sense resistor value such that the complete value is matching the typical mtp value (5 m? or 10 m?). ? trim the value with a resistor divider so that the (r7 / (r5 + r7)) (r1 + r pcb ) matches the mtp default value. r pcb is the resistance of copper wires and the resistance change of the sense resistor due to its soldering profile. to maximize accuracy and temperature stability, keep r pcb as low as possible. the sense resistor must have a temperature coefficient that is as low as possible. to prevent magnetic coupling, keep the length and the area of the connections between the sense resistor and the sgnd and isns pins as small as possible. connect the exposed die pad to the gnd pin. ensure that high currents flowing through the plane below the ic is prevented. 13.3 voltage loop in the application diagram, an integrator network is connected between the vsns pin and the optocoupler. the recommended values of these components are: ?
