TPS3828-50DBVR

Texas Instruments · Supervisor and Reset ICs · SOT-23-5

TPS3828-50DBVR from Texas Instruments, in a SOT-23-5. 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 RESET output Active-low reset output, open-drain on the TPS3828. Asserts low while VDD is below VIT- (typ 4.55V for the -50 option) or during a manual/watchdog reset event, and stays low for the internal 200 ms delay after the fault clears. Requires an external pull-up resistor to VDD (or another logic supply) since it cannot source current.
2 GND power_in Ground/return for the supply and reference for all logic and threshold voltages.
3 MR input Manual reset input, active low. Driving MR low forces RESET low; RESET is then held low for the 200 ms reset timeout after MR returns high. Leave open or tie to VDD when unused (internal pull-up is not guaranteed - see datasheet).
4 WDI input Watchdog timer input. A rising or falling edge on WDI clears the internal 1.6 s watchdog timer; if WDI stays static (high or low) longer than the timeout, RESET is driven low. If unused, WDI must be left high-impedance (floating) to avoid spurious resets.
5 VDD power_in Supply input, absolute max -0.3V to 6V, recommended 5V (nominal) for the -50 option. Also the monitored rail: RESET asserts when VDD falls below VIT- (typ 4.55V) and clears after VDD rises above VIT-+VHYS plus the 200 ms delay. Bypass with a 100 nF ceramic capacitor to GND close to the pin.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (None pp, sha256 f0ddd0a85e54c699, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
