TPS3620-33DGKT from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | power_out | Supply output switched between VDD (via ~1-Ω PMOS) and VBAT (via ~15-Ω switch) supporting 300 mA continuous current. |
| 2 | VDD | power_in | Main supply input from 1.65 V to 5.5 V with maximum 40 µA supply current in normal mode. |
| 3 | GND | power_in | Ground reference for all voltages and current return path. |
| 4 | PFI | input | Power-fail input compared against 1.15 V reference over voltage range 0 to VDD + 0.3 V with 12 mV hysteresis. |
| 5 | PFO | output | Power-fail output that asserts high when PFI exceeds 1.15 V threshold with 12 mV hysteresis. |
| 6 | MR | input | Manual reset input from -0.3 V to VDD + 0.3 V that pulls RESET low with minimum 100 ns pulse width. |
| 7 | RESET | output | Active-low reset output asserted when supply >1.1 V or VDD falls below threshold, with 100 ms fixed delay. |
| 8 | VBAT | power_in | Backup battery input from 1.5 V to 5.5 V (can exceed VDD) with maximum 0.5 µA supply current. |
