TPS3823-33DBVR

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

TPS3823-33DBVR 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. Asserts low when VDD drops below the 2.93 V threshold (VIT-) or when MR is pulled low, and stays low for the reset delay td (200 ms typ) after VDD returns above threshold. Push-pull output, VOH >= 0.8*VDD at IOH = -30 µA, VOL <= 0.4 V at IOL = 1.2 mA.
2 GND power_in Ground reference for the device. All voltages are with respect to this pin.
3 MR input Manual reset input, active low. A logic low on MR forces RESET active; RESET stays asserted for td (200 ms typ) after MR returns high. VIH >= 0.7VDD, VIL <= 0.3VDD, minimum pulse width 1 µs. Has an internal ~52 kΩ pull-up to VDD, so may be left open if unused.
4 WDI input Watchdog input. Must see a rising or falling transition within the watchdog timeout t_tout (1.6 s typ on TPS3823) or RESET is asserted for td (200 ms typ). VIH >= 0.7VDD, VIL <= 0.3VDD, minimum pulse width 100 ns. Leave floating/unconnected to disable the watchdog.
5 VDD power_in Supply input, 1.1 V to 5.5 V operating range (6 V absolute maximum). Monitored against the internal 2.93 V threshold (VIT-, TPS3823-33). Bypass with a 0.1 µF ceramic capacitor near the pin for threshold stability.

CAD (KiCad official)

  • Symbol: TPS3823-33DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tps3823-33dbvr-etched.step / tps3823-33dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3823-33dbvr.step / tps3823-33dbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps3823-33dbvr.step 85 KB You want the bare part, or you mark your own boards.
tps3823-33dbvr-etched.step 3.0 MB You want the part with TPS3823-33DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 703 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
