TPS389018QDSERQ1

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

TPS389018QDSERQ1 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 This pin is connected to the voltage to be monitored; RESET goes low when SENSE falls below the negative threshold VITN and goes high when SENSE rises above the positive threshold VITP.
2 GND power_in Ground reference pin for the device.
3 MR input Driving the manual reset pin MR low causes RESET to go low (assert).
4 VDD power_in Supply voltage pin with a recommended range of 1.5 V to 5.5 V and an absolute maximum of 7 V; good analog design practice is to place a 0.1-µF ceramic capacitor close to this pin.
5 CT passive A ground-referenced capacitor connected to this pin sets the RESET deassert delay, tPD(r) (sec) = CCT (µF) × 1.07 + 25 µs (nom), with CCT limited to 0 to 26 µF.
6 RESET output Open-drain output that is driven low when MR is low or SENSE is below VITN, and requires a pullup resistor from 10 kΩ to 1 MΩ; RESET pin current is limited to ±5 mA.
