TPS2049DR 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 | GND | power_in | Ground reference for the device; all device voltages are specified with respect to GND. |
| 2 | IN | power_in | Power-switch input voltage, recommended range 2.7 V to 5.5 V; the UVLO keeps the switch off below approximately 2 V. |
| 3 | IN | power_in | Power-switch input voltage, recommended range 2.7 V to 5.5 V; pin 3 is a second IN pin tied to the same input node as pin 2. |
| 4 | EN | input | Active-low enable input that turns the power switch on when logic low; VI(EN) is rated 0 V to 5.5 V and is TTL/CMOS compatible. |
| 5 | OC | output | Active-low open-drain overcurrent/overtemperature report output, deglitched by about 10 ms; VOL is 0.4 V max at 5 mA sink. |
| 6 | OUT | power_out | Power-switch output of the 600-mΩ N-channel high-side MOSFET; continuous output current recommended 0 to 100 mA. |
| 7 | OUT | power_out | Power-switch output of the 600-mΩ N-channel high-side MOSFET; continuous output current recommended 0 to 100 mA; tied to the same output node as pins 6 and 8. |
| 8 | OUT | power_out | Power-switch output of the 600-mΩ N-channel high-side MOSFET; continuous output current recommended 0 to 100 mA; tied to the same output node as pins 6 and 7. |
