TPS3828-33DBVR

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

TPS3828-33DBVR 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, open-drain (TPS3828). Asserted low when VDD is below the 2.93 V threshold (VIT-), when MR is held low, or when the watchdog fails to be retriggered within tt(out). Requires an external pull-up resistor to a supply rail. IOL up to 1.2 mA at VOL <= 0.4 V.
2 GND power_in Ground reference for the device. All voltages are referenced to this pin.
3 MR input Manual reset input, active low. A low level on MR forces RESET active. Includes an internal 52 kOhm pull-up to VDD, so the pin may be left open if unused. VIL <= 0.3 x VDD; VIH >= 0.7 x VDD.
4 WDI input Watchdog input. A positive or negative transition on WDI within the watchdog timeout tt(out) (typ. 1.6 s) resets the watchdog timer. Failure to retrigger drives RESET active for td. Leaving WDI unconnected disables the watchdog. Minimum pulse width 100 ns.
5 VDD power_in Positive supply voltage input, monitored against the 2.93 V (typ) negative-going threshold VIT-. Operating range 1.1 V to 5.5 V (absolute max 6 V). Supply current IDD is typ. 15 uA (max 25 uA). A 0.1 uF ceramic bypass capacitor is recommended near the pin.

CAD (KiCad official)

  • Symbol: TPS3828-33DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tps3828-33dbvr-etched.step / tps3828-33dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3828-33dbvr.step / tps3828-33dbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps3828-33dbvr.step 85 KB You want the bare part, or you mark your own boards.
tps3828-33dbvr-etched.step 3.0 MB You want the part with TPS3828-33DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 711 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.
