# TPS3780DDBVR

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

TPS3780DDBVR 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 | VDD | power_in | Supply voltage input, 1.5 V to 6.5 V required. |
| 2 | OUT1 | tri_state | Open-drain output for SENSE1; driven low when SENSE1 falls below VIT-, floats high when SENSE1 rises above VIT+; requires external pull-up resistor. |
| 3 | OUT2 | tri_state | Open-drain output for SENSE2; driven low when SENSE2 falls below VIT-, floats high when SENSE2 rises above VIT+; requires external pull-up resistor. |
| 4 | SENSE2 | input | Monitored voltage input for second channel; external resistor divider input; OUT2 asserted when voltage drops below VIT-. |
| 5 | GND | power_in | Ground reference. |
| 6 | SENSE1 | input | Monitored voltage input for first channel; external resistor divider input; OUT1 asserted when voltage drops below VIT-. |

## CAD (KiCad official)

- Symbol: `TPS3780DDBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `tps3780ddbvr-etched.step` / `tps3780ddbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps3780ddbvr.step` / `tps3780ddbvr.glb` are the bare package body.
