FUNCTION
Upper gate drive output. Connect to gate of high-side power N-Channel MOSFET.
Floating bootstrap supply pin for the upper gate drive. Connect the bootstrap capacitor between this pin and the
PHASE pin. The bootstrap capacitor provides the charge to turn on the upper MOSFET. See “Internal Bootstrap
Device” on page 7 for guidance in choosing the capacitor value.

NC
PWM
No connect.
The PWM signal is the control input for the driver. The PWM signal can enter three distinct states during operation.
See “Advanced PWM Protocol (Patent Pending)” on page 6 for further details. Connect this pin to the PWM output
of the controller.

VCC
Bias and reference ground. All signals are referenced to this node. It is also the power-ground return of the driver.
Lower gate drive output. Connect to gate of the low-side power N-Channel MOSFET.
Connect this pin to 5V bias supply. This pin supplies power to the upper gate and lower gate drive. Place a high
quality low ESR ceramic capacitor from this pin to GND.

PHASE
Enable input pin. Connect this pin high to enable driver and low to disable driver.
Connect this pin to the SOURCE of the upper MOSFET and the DRAIN of the lower MOSFET. This pin provides
a return path for the upper gate drive.
