UCC27531DBVT

Texas Instruments · Gate Drivers · SOT-23-6

UCC27531DBVT 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 EN input Enable input: pulling EN to GND disables the output, while pulling it high or leaving it open enables the output, with EN rated for -5 V to 25 V recommended.
2 IN input Driver non-inverting input, with a recommended input voltage range of -5 V to 25 V and an absolute continuous maximum of 27 V.
3 VDD power_in Bias supply input, with a recommended operating range of 10 V to 32 V and an absolute maximum of 35 V.
4 GND power_in Ground; all signals are referenced to this node.
5 OUTL output Pull-down output of the split driver, rated for a 5-A sink peak current.
6 OUTH output Pull-up output of the split driver, rated for a 2.5-A source peak current.
