TPS2491DGSR

Texas Instruments · Supervisor And Reset ICs · VSSOP-10-0.5mm

TPS2491DGSR from Texas Instruments, in a VSSOP-10-0.5mm. 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 Device enable input
2 VREF power_in Reference voltage output used to set power threshold on PROG pin, with 0 to 2 mA source current capability
3 PROG input Power-limit setting input, 0.4 V to 4 V recommended operating range, 2 mA sink current maximum
4 TIMER bidirectional Fault timing capacitor input/output connection
5 GND power_in Ground
6 PG tri_state Power good reporting open-drain output, 10 mA sink current maximum
7 OUT input Output voltage feedback input, 0 V to 80 V recommended operating range
8 GATE output Gate output for driving external N-channel MOSFET
9 SENSE input Current-limit sense input
10 VCC power_in Supply input voltage, 9 V to 80 V operating range
