# TPS3103H20DBVR

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

TPS3103H20DBVR 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 | Low-level active reset output with push-pull or open-drain output stage. |
| 2 | GND | power_in | Ground reference. |
| 3 | MR | input | Manual reset input; pulling low forces RESET output low, which remains low for a timeout period after MR returns high; connect to VDD or leave unconnected when not used. |
| 4 | PFI | input | Power fault input compared to internal 0.551V reference with no additional delay; connect to VDD when not used. |
| 5 | PFO | output | Power fault output which goes high when PFI voltage exceeds 0.551V. |
| 6 | VDD | power_in | Supply voltage; powers the device and is monitored to generate RESET output. |
