# TPS2812DR

**Texas Instruments** · Gate Drivers · SOIC-8

TPS2812DR from Texas Instruments, in a SOIC-8. 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 | REG_IN | power_in | Regulator input accepting 8 V to 40 V supply voltage to enable internal voltage regulator for REG_OUT. |
| 2 | 1IN | input | Noninverting input 1 with positive-going threshold 5.8 to 9 V and negative-going threshold 1 to 4.2 V at VCC = 10 V. |
| 3 | GND | power_in | Ground reference and return current path for all device circuits. |
| 4 | 2IN | input | Noninverting input 2 with positive-going threshold 5.8 to 9 V and negative-going threshold 1 to 4.2 V at VCC = 10 V. |
| 5 | 2OUT | output | Noninverting driver output 2 delivering 2 A peak current with high-level output 8 to 9.1 V at -100 mA and low-level 1 to 2 V at 100 mA load. |
| 6 | VCC | power_in | Positive supply voltage with recommended operating range 4 to 14 V and absolute maximum -0.3 to 15 V; power supply for all internal circuits. |
| 7 | 1OUT | output | Noninverting driver output 1 delivering 2 A peak current with high-level output 8 to 9.1 V at -100 mA and low-level 1 to 2 V at 100 mA load. |
| 8 | REG_OUT | power_out | Regulator output providing up to 20 mA maximum continuous output current from internal voltage regulator. |
