UCC57142ADBVR

Texas Instruments · IC · SOT-23-6

UCC57142ADBVR from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OCP input Current sense input; when an overcurrent signal is detected the driver pulls EN/FLT low and forces OUT low (abs max -10 V to 12 V, recommended -5 V to 10 V).
2 COM power_in Device ground, the reference for all device voltages.
3 OUT output Output of the driver, typical 3 A sink and 3 A source peak current, ranging from COM to VDD.
4 VDD power_in Driver bias supply, absolute maximum 30 V and recommended 14.5 V to 26 V for the 12 V UVLO option (8.5 V to 26 V for the 8 V UVLO option).
5 EN/FLT bidirectional Enable input and fault report pin that needs an external pullup, is pulled low to report OCP, UVLO and over temperature faults, and disables the driver when pulled low (0 V to 26 V recommended).
6 IN input Input of the driver, DC voltage from -2 V to 26 V recommended (-5 V to 30 V absolute maximum).
