TPS3705-33DGNR

Texas Instruments · Supervisor And Reset ICs · MSOP-8-EP

TPS3705-33DGNR from Texas Instruments, in a MSOP-8-EP. 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 RESET output Active-low reset output that becomes valid once VDD exceeds 1.1 V and is asserted when VDD falls below the threshold VIT-, with a fixed 200 ms power-up delay; maximum low output current is 5 mA.
2 WDO output Watchdog timer output (TPS3705-xx only); maximum low output current is 5 mA and maximum high output current is -5 mA.
3 MR input Manual reset input; VIH is 0.7 × VDD minimum and VIL is 0.3 × VDD maximum, with input rise and fall rates at MR limited to 100 ns/V.
4 VDD power_in Supply voltage input with a recommended range of 2 V to 6 V and an absolute maximum of 7 V relative to GND.
5 GND power_in Ground reference; all device voltage ratings are stated with respect to GND.
6 PFI input Power-fail comparator input whose voltage must stay within -0.3 V to VDD + 0.3 V.
7 PFO output Power-fail comparator output used to flag a low supply condition; maximum low output current is 5 mA.
8 WDI input Watchdog timer input (TPS3705-xx only); VIH is 0.7 × VDD minimum and VIL is 0.3 × VDD maximum, with input rise and fall rates limited to 100 ns/V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
