# TPS2066CDGNR-2

**Texas Instruments** · Power Distribution Switches · MSOP-8

TPS2066CDGNR-2 from Texas Instruments, in a MSOP-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 | GND | power_in | Ground connection for the device. |
| 2 | IN | power_in | Input voltage and power-switch drain, operating from 4.5 V to 5.5 V with a 0.1 µF or greater ceramic capacitor from IN to GND placed close to the IC. |
| 3 | EN1 | input | Enable input for channel 1, where logic high turns on the power switch; the enable input range is 0 V to 5.5 V. |
| 4 | EN2 | input | Enable input for channel 2, where logic high turns on the power switch; the enable input range is 0 V to 5.5 V. |
| 5 | FLT2 | output | Active-low open-drain fault output asserted during overcurrent or overtemperature on channel 2, with a sink current of 0 to 5 mA permitted into FLTx. |
| 6 | OUT2 | output | Power-switch output for channel 2, connected to the load, rated for 1 A continuous output current on this device. |
| 7 | OUT1 | output | Power-switch output for channel 1, connected to the load, rated for 1 A continuous output current on this device. |
| 8 | FLT1 | output | Active-low open-drain fault output asserted during overcurrent or overtemperature on channel 1, with a sink current of 0 to 5 mA permitted into FLTx. |
