DUAL OUTPUT SWITCH

The UC27136 UC37136 bipolar dual Switch contains all the control and drive circuitry required to drive resistive, capacitive, and inductive loads as in industrial Sensor applications. The output drivers are 250-mA NPN power switches that CAN Switch a load between a voltage supply up to 35 V and GND with a continuous output current rating of 250 mA, combined or individually. Internal 46-V Zener clamps are provided to clamp collector-to-emitter NPN power Switch voltages to safe levels when driving inductive loads. The two outputs CAN be configured in any combination of high side (load to GND) or low side (load to VCC). The output of Switch 1 is fixed in phase with the CMOS compatible IN1 pin. The CMOS compatible exclusive OR Gate inputs, IN2 and INV2, determine the output phase of Switch 2. An under voltage lockout (UVLO) function is provided to disable both output NPN Power Switches until VCC is greater than 8 V. Both output NPN Power Switches CAN also be disabled past the UVLO enable trip point by an external user programmable time delay capacitor. An internal current limit function enables a low on/off duty cycle of the NPN Power Switches should the dc current go beyond 1 A. An internal thermal shutdown function disables the switches if the IC temperature reaches 155C such as in an overcurrent condition. By Texas Instruments
