TPS2042BDR

Texas Instruments · AC-DC Controllers and Regulators · SOIC-8

TPS2042BDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Device ground reference.
2 IN power_in Input supply voltage to both high-side power switches. Operating range 2.7V to 5.5V. Bypass locally with a 0.1µF ceramic to GND.
3 EN1 input Active-low enable for channel 1 (IN→OUT1). Logic low turns the switch on. TTL/CMOS compatible; do not leave floating.
4 EN2 input Active-low enable for channel 2 (IN→OUT2). Logic low turns the switch on. TTL/CMOS compatible; do not leave floating.
5 OC2 output Active-low, open-drain overcurrent fault flag for channel 2. Requires an external pull-up resistor. Asserts low during current-limit or thermal-shutdown events on OUT2; deglitched to reject transients.
6 OUT2 power_out Switched power output for channel 2 (from IN via internal 70mΩ MOSFET). 500mA continuous rating; 0.75-1.25A current-limit range. Recommend 0.1µF + 22µF bypass at the load.
7 OUT1 power_out Switched power output for channel 1 (from IN via internal 70mΩ MOSFET). 500mA continuous rating; 0.75-1.25A current-limit range. Recommend 0.1µF + 22µF bypass at the load.
8 OC1 output Active-low, open-drain overcurrent fault flag for channel 1. Requires an external pull-up resistor. Asserts low during current-limit or thermal-shutdown events on OUT1; deglitched to reject transients.
