# TPS3808G01QDBVRQ1

**Texas Instruments** · Supervisor And Reset ICs · SOT-23-6

TPS3808G01QDBVRQ1 from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RESET | output | Open-drain reset output that is pulled to a low impedance state when asserted (SENSE below VIT or MR low); it requires a pullup resistor from 10 kΩ to 1 MΩ and can reach voltages higher than VDD. |
| 2 | GND | power_in | Ground reference for the device; connect to the ground plane. |
| 3 | MR | input | Manual reset input; driving it low asserts RESET, and it is internally pulled up to VDD by a 90-kΩ resistor. |
| 4 | CT | input | Reset period programming pin; connecting it to VDD through a 40-kΩ to 200-kΩ resistor or leaving it open gives fixed delay times, while a ground-referenced capacitor of 100 pF or more gives a user-programmable delay. |
| 5 | SENSE | input | Voltage sense input connected to the monitored voltage; RESET is asserted when this pin drops below the threshold voltage VIT. |
| 6 | VDD | power_in | Supply voltage input; good analog design practice is to place a 0.1-μF ceramic capacitor close to this pin. |
