data sheet 6 rev. 1.0, 2012-03-01 TLE7250G functional description 4 functional description can is a serial bus system that connects microcontrollers , sensors and actuators for re al-time control applications. the use of the c ontrol a rea n etwork (abbreviated can) within road vehi cles is described by the international standard iso 11898. according to th e 7-layer osi reference model, the physical layer of a can bus system specifies the data transmission from one can node to all other available can nodes within the network. the physical layer specification of a can bus system includes all electrical and mechanical specifications of a can network. the can transceiver is part of the physical layer specification. seve ral different physical layer definitions of can networks have been developed in recent years. the TLE7250G is a high speed can transceiver without a dedicated wake-up function. high speed can transceive rs without a wake-up function are defined by the international standard iso 11898-2. 4.1 high speed c an physical layer figure 3 high speed can bus signals and logic signals v cc can_h can_l txd v cc = high speed can power supply txd = input from the microcontroller rxd = output to the microcontroller canh = voltage on the canh input/output canl = voltage on the canl input/output v diff = differential voltage between canh and canl v diff = v canh C v canl rxd v diff v cc v cc t t t t v diff = iso level dominant v diff = iso level recessive dominant recessive
TLE7250G functional description data sheet 7 rev. 1.0, 2012-03-01 the TLE7250G is a high speed can transceiver, operating as an interface between the can controller and the physical bus medium. an hs can network is a two-wire, di fferential network, which allows data transmission rates up to 1 mbps. the characteristics of an hs can network are the two signal states on the can bus: ?dominant? and ?recessive? (see figure 3 ). the canh and canl pins are the interface to the can bus and both pins operate as an input and output. the rxd and txd pins are the interface to the microcontrolle r. the txd pin is the serial data input from the can controller, and the rxd pin is the serial data output to the can controller. as shown in figure 1 , the hs can transceiver TLE7250G includes a receiver and a transmitter unit, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. the hs can transceiver TLE7250G converts the serial data stream which is available on the transmit data input txd, into a differential output signal on the can bus, provided by the canh and canl pins. th e receiver stage of the TLE7250G monitors the data on the can bus and converts them to a serial, single-ended signal on the rxd output pin. a logical ?low? signal on the txd pin creates a ?dominant? signal on the can bu s, followed by a logical ?low ? signal on the rxd pin (see figure 3 ). the feature of broadcasting data to the can bus and listening to the data traffic on the can bus simultaneously is essential to support the bit-to-bit arbitration within can networks. the voltage levels for hs can transceivers are defi ned by the iso 11898-2 and the iso 11898-5 standards. whether a data bit is ?dominant? or ?recessive? depends on the voltage difference between the canh and canl pins: v diff = v canh - v canl . in comparison with other differential netw ork protocols, the differential signal on a can network can only be larger than or equal to 0 v. to transmit a ?dominant? signal to the can bus, the differential signal v diff is larger than or equal to 1.5 v. to receive a ?recessive? si gnal from the can bus, the differential v diff is smaller than or equal to 0.5 v. ?partially-supplied? high speed can networks are thos e where the can bus nodes of one common network have different power supply conditions. some nodes are co nnected to the common power supply, while other nodes are disconnected from the power supply and in power-do wn state. regardless of whether the can bus subscriber is supplied or not, each subscriber connected to the common bus media must not interfere with the communication. the TLE7250G is designed to support ?par tially-supplied? networks. in power-down state, the receiver input resistors are switched off and the transceiver input has a high resistance.
data sheet 8 rev. 1.0, 2012-03-01 TLE7250G functional description 4.2 modes of operation three different modes of operation are available on the TLE7250G. each mode has specific characteristics in terms of quiescent current or data transmission. nen and nrm are used as the digital input pins for mode selection. figure 4 illustrates the different mode c hanges depending on the status of the nen and nrm pins. after supplying v cc to the hs can transceiver, the tl e7250g starts in stand-by mode. the internal pull-up resistors set the TLE7250G to stand-by mode by default. if the mi crocontroller is up and running, the TLE7250G can switch to any mode of operation within the time period for mode change t mode . figure 4 modes of operation the TLE7250G has 3 major modes of operation: ? stand-by mode ? normal-operating mode ? receive-only mode table 2 modes of operation mode nrm nen bus bias comments normal-operating mode ?high? ?low? v cc /2 the transmitter is active. the receiver is active. stand-by ?low? or ?high? ?high? gnd the transmitter is disabled. the receiver is disabled. receive-only ?low? ?low? v cc /2 the transmitter is disabled. the receiver is active. v cc off ?low? or ?high? ?low? or ?high? floating the transmitter is disabled. the receiver is disabled. nrm = 0 nen = 0 nrm = 1 nen = 0 undervoltage detection on v cc power-down v cc < v cc(uv) start C up supply v cc nen = 1 stand-by mode nrm = 0/1 nen = 0 nrm = 1 nen = 0 receive-only mode nrm = 0 nrm = 0 nen = 0 nrm = 0/1 nen = 1 nrm = 0/1 nen = 1 nrm = 1 nen = 0 normal-operating mode
TLE7250G functional description data sheet 9 rev. 1.0, 2012-03-01 4.3 normal-operating mode in the normal-operating mode, the hs can transceiver tle7 250g sends the serial data stream on the txd pin to the can bus. the data on the can bus is displayed at th e rxd pin simultaneously. in the normal-operating mode, all functions of the TLE7250G are active: ? the transmitter is active and drives data from the txd to the can bus. ? the receiver is active and provides t he data from the can bus to the rxd pin. ? the bus biasing is set to v cc /2. ? the undervoltage monitoring at the power supply v cc is active. to enter the normal-operating mode, set the pin nrm to logical ?high? and the pin nen to logical ?low? (see table 2 or figure 4 ). both pins, the nen pin and the nrm pin have internal pull-up resistors to the power-supply v cc . 4.4 receive-only mode the receive-only mode can be used to test the connection of the bu s medium. the TLE7250G can still receive data form the bus, but the transmitter is disabled and he nce, no data can be sent to the can bus. all other functions are active: ? the transmitter is disabled and data, which is available on the txd pin, is blocked and not sent to the can bus. ? the receiver is active and provides the data from the can bus to the rxd output pin. ? the bus biasing is set to v cc /2. ? the undervoltage monitoring on the power supply v cc is active. to enter the receive-only mode, set the pin nrm to logical ?low? and the pin nen to logical ?low? (see table 2 or figure 4 ). in case the receive-only mode is not used, the nrm pin can be left open. 4.5 stand-by mode the stand-by mode is an idle mode of the TLE7250G with optimized power consumpt ion. in the stand-by mode, the TLE7250G can not send or receive any data. the transmitter and the receiver are disabled. both can bus pins, canh and canl are connected to gnd via the input resistors. ? the transmitter is disabled. ? the receiver is disabled. ? the input resistors of the receiver unit are connected to gnd. ? the undervoltage monitoring at the power supply v cc is active. to enter the stand-by mode, set the pin nen to logical ?h igh?, the logical state of the nrm pin has no influence on the mode selection (see table 2 or figure 4 ). both pins, the nen and the nrm pin have an internal pull-up resistor to the power-supply v cc . if the stand-by mode is not used in the application, the nen pin needs to be connected to gnd. in case the nrm pin is set to logical ?low? in the stand-b y mode, the internal pull-up resistor causes an additional quiescent current from v cc to gnd, therefore it is recommended to set the nrm pin to logical ?high? in stand-by mode or leave the pin open, if the receiv e-only mode is not used in the application. 4.6 power-down state the power-down state means that the TLE7250G is not supplied. in power- down state, the differential input resistors of the receiver stage are switched off. the canh and canl bus interface of the TLE7250G acts as high- impedance input with a very small leakage current. the hi gh-ohmic input does not influence the ?recessive? level of the can network and allows an optimize d eme performance of the entire can network.
data sheet 10 rev. 1.0, 2012-03-01 TLE7250G fail-safe functions 5 fail-safe functions 5.1 short-circuit protection the canh and canl bus outputs are short-circuit proof, either against gnd or a positive supply voltage. a current limiting circuit protects the transceiver against da mage. if the device heats up due to a continuous short on the canh or canl, the inte rnal overtemperature protection switches off the transmitter. 5.2 unconnected logic pins all logic input pins have an internal pull-up resistor to v cc . in case the v cc supply is activated and the logical pins are open or floating, the TLE7250G enters into the stand -by mode by default. in stand-by mode, the transmitter of the TLE7250G is disabled, the bus bi as is connected to gnd and the hs can TLE7250G transceiver does not influence the data on the can bus. 5.3 txd time-out function the txd time-out feature protects the can bus against pe rmanent blocking in case the logical signal on the txd pin is continuously ?low?. a continuous ?low? signal on the txd pin can have its root cause in a locked-up microcontroller or in a short on the printed circuit board for example. in normal-operating mode, a logical ?low? signal on the txd pin for the time t > t txd enables the txd time-out and the TLE7250G disables the transmitter (see figure 5 ). the receiver is still active and the data on the bus continues to be monitored by the rxd output pin. figure 5 txd time-out function figure 5 illustrates how the transmitter is deactivated and activated again. a permanent ?low? si gnal on the txd input pin activates the txd time-out function and deactivate s the transmitter. to release the transmitter after a txd time-out event, the TLE7250G requires a signal change on the txd input pin from logi cal ?low? to logical ?high?. 5.4 undervoltage detection the hs can transceiver TLE7250G is provided with undervoltage detection at the power supply v cc . in case of an undervoltage event on v cc , the undervoltage detection changes the operating mode of TLE7250G to the stand- by mode, regardless of the logical signal on the nen and nrm pins (see figure 6 ). if the transceiver TLE7250G recovers from the undervoltage condition, the operating m ode is restored to the programmed mode by the logical pins nen and nrm. txd t t canh canl rxd t txd time-out txd timeCout released t > t txd
