# TPS3808G33DRVT

**Texas Instruments** · Supervisor And Reset ICs · WSON-6-EP(2x2)

TPS3808G33DRVT from Texas Instruments, in a WSON-6-EP(2x2). 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 | VDD | power_in | Power supply voltage input (1.7V to 6.5V); place a 0.1µF ceramic capacitor near this pin. |
| 2 | SENSE | input | Sense input to monitor supply voltage; RESET becomes active when voltage drops below threshold voltage VIT. |
| 3 | CT | input | Reset delay programming input; connect through 40kΩ to 200kΩ resistor to VDD for 300ms delay, leave open for 20ms delay, or connect to ≥100pF capacitor to ground for 1.25ms to 10s user-programmable delay. |
| 4 | MR | input | Manual reset input with 90kΩ internal pull-up resistor to VDD; driving to logic low makes RESET become active. |
| 5 | GND | power_in | Ground reference. |
| 6 | RESET | tri_state | Open-drain reset output that is driven to low impedance state when active (SENSE below VIT or MR at logic low); use 10kΩ to 1MΩ external pull-up resistor. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
