DESCRIPTION
SIP43101 is a dual power switch IC which contains all control and power switching circuitry required to drive resistive and inductive loads in industrial applications. The output switches are NPN power transistors which can be configured as either high-side or low-side switches. These switches can operate from voltages as high as 35 V and have a continuous output current rating of 200 mA, combined or individually. Internal zener diodes are provided to clamp the power switch voltages to safe levels when driving inductive loads. The IN1 pin is a non-inverting input which controls the output of switch 1. A 2-input Exclusive OR gate input controls switch 2, allowing switch 2 to be controlled by either an inverting or non-inverting control signal. SIP43101 contains under voltage lockout, UVLO, a user definable turn on delay, current limit, short circuit protection, and thermal shutdown. SIP43101 is available in 16-pin TSSOP and PowerPAKr MLP-44 packages for operation over the temperature range of -40 to 85 C.

DETAILED PIN DESCRIPTION
CDEL A capacitor connected to this pin is used to set the duration the turn on delay. The delay starts after the UVLO threshold has been reached. E1 This pin is the emitter of Switch 1. This pin is connected to the load in the High-Side Switch configuration, and is connected to Ground in the Low-Side configuration. E2 IN1 This pin controls the state of the output NPN switch 1. A Logic 0 holds the switch off while a Logic 1 turns the switch on. This pin is the emitter of switch 2. This pin is connected to the load in the High-Side switch configuration, and is connected to Ground in the Low-Side configuration. C1 IN2A, IN2B These pins are the inputs to the Exclusive OR gate that controls the state of the output NPN switch 2. This allows the use of either a non-inverting or an inverted signal to control the switch. Refer to the truth table for the logic function description. This pin is the collector of switch 1. This pin is connected to the VCC in the High-Side switch configuration, and is connected to the load in the Low-Side configuration. C2 This pin is the collector of switch 2. This pin is connected to the VCC in the High-Side switch configuration, and is connected to the load in the Low-Side configuration. FAULT This pin is an open collector output that is pulled to Ground in the event of a short circuit, an overcurrent, or a thermal shut down

DETAILED OPERATION
Turn On Delay The turn on delay prohibits the output switches from being turned on for a period of time after VCC has passed through 8 V and the undervoltage condition no longer exists. The UVLO function keeps the external CDEL capacitor discharged until VCC is greater than 8 V. Subsequently, an internal 2.5-mA current source charges the capacitor from GND to 4.7 V. A comparator detects when the voltage on CDEL passes through 4 V and enables the output switches. The delay time is a function of the capacitor value and is defined as 1.6 ms/nF. An external switch can be connected across the capacitor to disable the output switches and reset the time delay. Short Circuit and Overcurrent indication When an overcurrent or short circuit condition occurs on either switch, the SIP43101 enters a hiccup current limiting mode. In this mode, the capacitor on CDEL is discharged down to 3 V, thus turning off the output switches, and then is charged up to 4 V by a 2.5-mA internal current source, thus turning the switches on again. If the overcurrent or short circuit condition remains this cycle will continue. The switches are enabled at a very low duty cycle, minimizing the power dissipation and protecting the switches from damage. The FAULT output will switch to GND, indicating that an overload condition or short circuit condition exists.
