TPS389033KQDSERQ1 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 the voltage being monitored; RESET goes low when SENSE falls below the negative threshold VITN and goes high when SENSE rises above the positive threshold VITP, with a recommended SENSE voltage range of 0 V to 5.5 V. |
| 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; good analog design practice is to place a 0.1-µF ceramic capacitor close to this pin. |
| 5 | CT | passive | User-adjustable delay pin; a ground-referenced capacitor on CT sets the RESET deassertion delay as tPD(r) (s) = CCT (µF) × 1.07 + 25 µs (nom), with CCT up to 26 µF. |
| 6 | RESET | output | Open-drain output that is driven low when MR is low or SENSE is below VITN and stays low for the delay time after both conditions clear, requiring an external pullup of 10 kΩ to 1 MΩ and an RESET current limit of ±20 mA absolute maximum. |
