TPS389050QDSERQ1

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

TPS389050QDSERQ1 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 Voltage to be monitored; RESET goes low when SENSE falls below the negative threshold VITN and goes high when it rises above the positive threshold VITP.
2 GND power_in Ground reference pin for the device.
3 MR input Manual reset input; driving MR low causes RESET to go low (assert).
4 VDD power_in Supply voltage pin with a recommended power-supply range of 1.5 V to 5.5 V; good analog practice is a 0.1-µF ceramic capacitor placed close to this pin.
5 CT passive User-adjustable reset delay pin; a ground-referenced capacitor sets the RESET deassert delay as tPD(r) (sec) = CCT (µF) × 1.07 + 25 µs (nom), with CCT limited to 26 µF.
6 RESET output Open-drain output driven low when MR is low or SENSE is below VITN, and it remains low for the delay time after both MR is high and SENSE is above VITP; use a pullup resistor from 10 kΩ to 1 MΩ.
