TPS389033QDSERQ1 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 input to monitor; RESET asserts when voltage falls below VITN and deasserts when above VITP. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | MR | input | Manual reset input; pulling low asserts RESET output. |
| 4 | VDD | power_in | Supply voltage input (recommended operating range 1.5 V to 5.5 V); place 0.1-µF ceramic capacitor close to this pin. |
| 5 | CT | passive | Timing capacitor connection pin; external ground-referenced capacitor sets reset delay time per tPD(r) (s) = CCT (µF) × 1.07 + 25 µs (nom). |
| 6 | RESET | tri_state | Open-drain reset output (±20 mA absolute maximum); asserts low when SENSE falls below VITN or MR pulled low, remains low for delay period; requires 10 kΩ to 1 MΩ pullup resistor. |
