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.
