TPS28225DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | UGATE | output | Upper gate drive sink/source output; drives the gate of high-side N-Channel MOSFET with 2A source and 2A sink capability. |
| 2 | BOOT | bidirectional | Floating bootstrap supply pin for upper gate drive; connect bootstrap capacitor between BOOT and PHASE pins to charge for turn-on of upper MOSFET. |
| 3 | PWM | input | PWM control input signal with 2.0V to 13.2V amplitude; 3-state capable with self-adjustable thresholds and 250ns hold-off time for shutdown. |
| 4 | GND | power_in | Ground reference pin; all signals referenced to this node. |
| 5 | LGATE | output | Lower gate drive sink/source output with 0.4Ω sink impedance and 4A sink capability; drives low-side N-Channel MOSFET gate. |
| 6 | VDD | power_in | Bias supply input voltage range 4.5V to 8V; place high quality bypass capacitor from this pin to GND. |
| 7 | EN/PG | bidirectional | Enable/power good input/output pin with 1-MΩ impedance; pull high to enable and low to disable; internally pulled low on VDD below UVLO threshold or thermal shutdown. |
| 8 | PHASE | input | Connection to source of upper MOSFET and drain of lower MOSFET; provides return path for upper gate driver. |
