TPS3705-30DR

Texas Instruments · Supervisor And Reset ICs · SOIC-8

TPS3705-30DR from Texas Instruments, in a SOIC-8. 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 MR input Manual reset input; the datasheet gives a rise and fall rate limit of 100 ns/V at MR or WDI.
2 VDD power_in Supply voltage pin; the recommended operating range is 2 V to 6 V and the absolute maximum is 7 V.
3 GND power_in Ground reference for all voltages, which are specified with respect to GND.
4 PFI input Power-fail comparator input, with a voltage range of -0.3 V to VDD + 0.3 V.
5 PFO output Power-fail comparator output for power-fail or low-battery warning.
6 WDI input Watchdog timer input (TPS3705-xx only); the rise and fall rate limit is 100 ns/V.
7 RESET output Active-low reset output, asserted while VDD is below the threshold VIT+ and driven low when VDD drops below VIT-.
8 WDO output Watchdog timer output (TPS3705-xx only).
