# TPS3847108DBVR

**Texas Instruments** · Supervisor And Reset ICs · SOT-23-5

TPS3847108DBVR from Texas Instruments, in a SOT-23-5. 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 | Active-low push-pull reset output that stays low while VCC is below the factory-trimmed threshold and goes high after the reset delay time (td) once VCC is above the positive-going threshold. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | NC | unconnected | No internal connection. |
| 4 | MR | input | Manual reset input; pulling it low forces RESET low regardless of the VCC voltage, and after MR returns high RESET goes high after td if VCC is above the positive-going threshold. |
| 5 | VCC | power_in | Power supply and monitored voltage, with TI recommending a small 0.1-µF bypass capacitor placed near this pin. |
