TPS3808G33QDBVRQ1

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

TPS3808G33QDBVRQ1 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. Driven low when SENSE drops below VIT (3.07 V typ) or MR is pulled low; released high after the programmed reset delay once SENSE is above VIT and MR is high. Requires a 10 kΩ to 1 MΩ pull-up (may pull to a rail higher than VDD). Max IRESET = 5 mA.
2 GND power_in Device ground reference.
3 MR input Active-low manual reset input. Driving this pin low asserts RESET. Internally pulled to VDD through a ~90 kΩ resistor (70 kΩ min), so it may be left floating if unused. VIL ≤ 0.3·VDD, VIH ≥ 0.7·VDD.
4 CT input Reset-delay programming pin. Leaving open selects the fixed 20 ms delay; tying to VDD via a 40 kΩ resistor selects 300 ms; connecting a ground-referenced capacitor ≥100 pF programs a user delay of 1.25 ms to 10 s. Input capacitance ~5 pF.
5 SENSE input Voltage-sense input connected to the monitored supply. RESET is asserted when this pin drops below the threshold voltage VIT (3.07 V typical for the G33 option). Very high input impedance; ISENSE ≤ 25 nA. Recommended range 0 V to VDD.
6 VDD power_in Supply voltage, 1.8 V to 6.5 V (absolute max 7 V). Typical IDD = 2.4 µA at 3.3 V. Bypass with a 0.1 µF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: TPS3808G33QDBVRQ1
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tps3808g33qdbvrq1-etched.step / tps3808g33qdbvrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tps3808g33qdbvrq1.step / tps3808g33qdbvrq1.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps3808g33qdbvrq1.step 97 KB You want the bare part, or you mark your own boards.
tps3808g33qdbvrq1-etched.step 3.9 MB You want the part with TPS3808G33QDBVRQ1 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 896 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.
