TPS28225DRBR from Texas Instruments, in a SON-8-EP(3x3). 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 | UGATE | output | Upper gate drive sink/source output, connect to high-side N-Channel MOSFET gate. |
| 2 | BOOT | bidirectional | Floating bootstrap supply pin for upper gate drive; connect bootstrap capacitor between this pin and PHASE pin. |
| 3 | PWM | input | PWM control input supporting three distinct operating states. |
| 4 | GND | power_in | Ground reference pin; all signals are referenced to this node. |
| 5 | LGATE | output | Lower gate drive sink/source output, connect to low-side N-Channel MOSFET gate. |
| 6 | VDD | power_in | 5-V bias supply input; place high quality bypass capacitor from this pin to GND. |
| 7 | EN/PG | bidirectional | Enable/power good input/output with 1-MΩ impedance; pull high to enable or low to disable (quiescent < 350-μA); internally pulled low on UVLO or over-temperature shutdown. |
| 8 | PHASE | input | Phase node connected to upper MOSFET source and lower MOSFET drain; provides return path for upper gate driver. |
| 9 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
