TPS3808G30DBVR

Texas Instruments · Supervisor and Reset ICs · SOT-23-6

TPS3808G30DBVR from Texas Instruments, in a SOT-23-6. 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, open-drain RESET output. Asserted (driven low) whenever SENSE is below the threshold voltage VIT (2.79 V for G30) or when MR is pulled low. Requires an external pull-up resistor (10 kΩ to 1 MΩ), which may be tied to a rail higher than VDD. Remains low for the programmed reset delay after both SENSE > VIT and MR = high.
2 GND power_in Device ground reference.
3 MR input Active-low manual reset input. Driving MR low asserts RESET. Internally tied to VDD through a 90-kΩ pull-up resistor, so it may be left floating if unused. Recommended operating range 0 V to 6.5 V.
4 CT input Reset-period programming pin. Connect to VDD through a 40-kΩ to 200-kΩ resistor, leave open for the fixed 20 ms delay, connect to VDD directly for a 300 ms delay, or tie a ground-referenced capacitor ≥100 pF for a user-programmable delay from 1.25 ms to 10 s.
5 SENSE input Voltage-sense input. Connect to the rail to be monitored. When SENSE drops below the threshold voltage VIT (2.79 V for TPS3808G30, monitoring a 3 V rail), RESET is asserted. Recommended range 0 V to 6.5 V.
6 VDD power_in Supply voltage input, 1.7 V to 6.5 V recommended operating range (7 V absolute max). Place a 0.1 µF ceramic bypass capacitor close to this pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps3808g30dbvr.step 97 KB You want the bare part, or you mark your own boards.
tps3808g30dbvr-etched.step 3.3 MB You want the part with TPS3808G30DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 764 faces against 117 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.
