PIN
The PWM signal is the control input for the Channel 1 driver. The PWM signal can enter three distinct states during
operation, see the Tri-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 Tri-state PWM Input section under DESCRIPTION for further details. Connect this pin to the PWM
output of the controller.
Bias and reference ground. All signals are referenced to this node.
Lower gate drive output of Channel 1. Connect to gate of the low-side power N-Channel MOSFET.
This pin supplies power to both the lower and higher gate drives. Place a high quality low ESR ceramic capacitor
from this pin to PGND.
Power ground return of both low gate drivers.
No connection.
Lower gate drive output of Channel 2. Connect to gate of the low-side power N-Channel MOSFET.
Connect this pin to the SOURCE of the upper MOSFET and the DRAIN of the lower MOSFET in Channel 2. This
pin provides a return path for the upper gate drive.
Upper gate drive output of Channel 2. Connect to gate of high-side power N-Channel MOSFET.
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.
Upper gate drive output of Channel 1. Connect to gate of high-side power N-Channel MOSFET.
Connect this pin to the SOURCE of the upper MOSFET and the DRAIN of the lower MOSFET in Channel 1. This
pin 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.
Connect this pad to the power ground plane (GND) via thermally enhanced connection.
