TPS389025DSER 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 | SENSE is the monitored voltage input, where RESET goes low when the voltage falls below VITN and goes high when it rises above VITP, with VSENSE rated 0 V to 5.5 V. |
| 2 | GND | power_in | GND is the ground reference pin for the device. |
| 3 | MR | input | Driving the manual reset (MR) pin low causes RESET to assert (go low). |
| 4 | VDD | power_in | VDD is the supply voltage pin, with a recommended range of 1.5 V to 5.5 V, and good analog practice is a 0.1-µF ceramic capacitor placed close to the pin. |
| 5 | CT | passive | CT sets the user-adjustable RESET delay when a ground-referenced capacitor is connected, with tPD(r) = CCT (µF) × 1.07 + 25 µs (nom) and CCT limited to 0 to 22 µF. |
| 6 | RESET | output | RESET is an open-drain output that goes low when MR is low or SENSE is below VITN and stays low for the delay after MR is high and SENSE is above VITP, with a pullup resistor of 10 kΩ to 1 MΩ recommended. |
