# TPS28225TDRQ1

**Texas Instruments** · Gate Drivers · SOIC-8

TPS28225TDRQ1 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 and source output capable of sourcing 2 A and sinking 4 A for driving high-side power N-Channel MOSFET. |
| 2 | BOOT | power_in | Floating bootstrap supply pin for charging bootstrap capacitor connected between BOOT and PHASE to provide upper MOSFET gate drive voltage. |
| 3 | PWM | input | PWM control input signal with amplitude range 2-V to 13.2-V and three distinct operating states for controlling driver output. |
| 4 | GND | power_in | Ground reference pin with all signals referenced to this node. |
| 5 | LGATE | output | Lower gate-drive sink and source output capable of sourcing 2 A and sinking 4 A for driving low-side power N-Channel MOSFET. |
| 6 | VDD | power_in | Power supply input with nominal range 4.5-V to 8-V, requiring 0.22-µF to 4.7-µF bypass capacitor to GND. |
| 7 | EN/PG | tri_state | Enable and Power Good input-output with 1-MΩ impedance; drive HIGH to enable or LOW to disable; internally pulled low on UVLO threshold or overtemperature shutdown. |
| 8 | PHASE | input | Switching node connection to source of upper MOSFET and drain of lower MOSFET, providing reference return path for upper gate driver and bootstrap capacitor. |
