TPS28225DR

Texas Instruments · Gate Drivers · SOIC-8

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.
