# TPS3808G19DBVR

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

TPS3808G19DBVR 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 driven to low impedance when RESET is active (SENSE below threshold VIT or MR at logic low); pulled high by external 10kΩ to 1MΩ resistor. |
| 2 | GND | power_in | Ground reference connection. |
| 3 | MR | input | Manual reset input with internal 90kΩ pull-up resistor to VDD; driving low (≤0.3VDD) activates RESET output. |
| 4 | CT | input | Reset delay programming input; connect 40kΩ to 200kΩ resistor to VDD for 300ms fixed delay, leave open for 20ms fixed delay, or connect ≥100pF capacitor to GND for user-programmable 1.25ms to 10s delay. |
| 5 | SENSE | input | Voltage monitoring input; RESET becomes active when voltage on this pin drops below threshold voltage VIT. |
| 6 | VDD | power_in | Power supply voltage input (1.7V to 6.5V recommended); place 0.1μF ceramic capacitor near this pin for decoupling. |
