TPS3620-33DGKT

Texas Instruments · Monitors & Reset Circuits · VSSOP-8-0.65mm

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.
