Bias and reference ground. All signals are referenced to this node.
This pin supplies power to both the lower and higher gate drives in ISL6614. Its operating range is +5V to 12V. Place a high
quality low ESR ceramic capacitor from this pin to GND.
Logic control input that will force continuous conduction mode (HIGH state) or allow discontinuous conduction mode
(LOW state). Placing a series resistor in this input will allow the switching dead-time to be programmed.
It is the power ground return of both low gate drivers.
Logic control input that will enable (HIGH state) or disable (LOW state) the IC. Shutdown current is <1μA.
provides a return path for the upper gate drive.
Floating bootstrap supply pin for the upper gate drive of Channel 2. Connect the bootstrap capacitor between this pin and
the PHASE2 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.
Floating bootstrap supply pin for the upper gate drive of Channel 1. Connect the bootstrap capacitor between this pin and
the PHASE1 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.
provides a return path for the upper gate drive.
Connect this pin to a +5V bias supply. It supplies power to internal analog circuits. Place a high quality low ESR ceramic
capacitor from this pin to GND.
The PWM signal is the control input for the Channel 1 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.
The PWM signal is the control input for the Channel 2 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.
Connect this pad to the power ground plane (GND) via thermally enhanced connection.
