UGATE
Upper gate drive output. Connect to gate of high-side power N-Channel MOSFET.
2
2
BOOT
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 the Internal Bootstrap
Device section under DESCRIPTION for guidance in choosing the capacitor value.

N/C
No Connection.

PWM
The PWM signal is the control input for the driver. The PWM signal can enter three distinct states during operation, see
the three-state PWM Input section under DESCRIPTION for further details. Connect this pin to the PWM output of the
controller.
4
5
GND
Bias and reference ground. All signals are referenced to this node. It is also the power ground return of the driver.
5
6
LGATE
Lower gate drive output. Connect to gate of the low-side power N-Channel MOSFET.
6
7
VCC
Connect this pin to a +12V bias supply. Place a high quality low ESR ceramic capacitor from this pin to GND.
7
9
PVCC
This pin supplies power to both upper and lower gate drives in ISL6613A; only the lower gate drive in ISL6612A.
Its operating range is +5V to 12V. Place a high quality low ESR ceramic capacitor from this pin to GND.
8
10
PHASE
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.
9
11
PAD
Connect this pad to the power ground plane (GND) via thermally enhanced connection.
