TPS28226DR 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 | UGATE | output | Upper gate drive sink/source output, connected to the gate of the high-side power N-channel MOSFET. |
| 2 | BOOT | bidirectional | Floating bootstrap supply for the upper gate drive; the bootstrap capacitor connects between this pin and PHASE, and the absolute maximum boot voltage is 33 V to GND. |
| 3 | PWM | input | Control input from the controller PWM output that supports three states, including the 3-state shutdown, with an input voltage absolute maximum of 13.2 V. |
| 4 | GND | power_in | Ground pin to which all signals are referenced, and to which the exposed thermal pad should be connected directly. |
| 5 | LGATE | output | Lower gate drive sink and source output, connected to the gate of the low-side power N-channel MOSFET. |
| 6 | VDD | power_in | Bias supply pin that requires a high-quality bypass capacitor to GND; recommended VDD is 6.8 V to 8 V with an absolute maximum of 8.8 V. |
| 7 | EN/PG | bidirectional | Enable/power good input/output with 1-MΩ impedance that is driven High to enable and Low to disable, draws less than 350 µA when disabled, and is pulled low on VDD UVLO or over-temperature shutdown. |
| 8 | PHASE | input | Connects to the source of the upper MOSFET and the drain of the lower MOSFET, and provides the return path for the upper gate driver. |
