TPS389001DSET

Texas Instruments · Supervisor And Reset ICs · WSON-6(1.5x1.5)

TPS389001DSET from Texas Instruments, in a WSON-6(1.5x1.5). 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 SENSE input Monitored voltage input; RESET asserts when voltage falls below VITN and deasserts when voltage rises above VITP.
2 GND power_in Ground reference.
3 MR input Manual reset input; assert RESET by driving MR to logic low.
4 VDD power_in Supply voltage input (1.5 V to 5.5 V); place 0.1-µF ceramic capacitor close to this pin.
5 CT passive Capacitor timing pin; connect ground-referenced capacitor to set RESET delay time per tPD(r) = CCT (µF) × 1.07 + 25 µs.
6 RESET tri_state Open-drain output that asserts low when MR is low or SENSE is below VITN; requires 10 kΩ to 1 MΩ pullup resistor.
