NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin
plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL6208C. For more information on MSL please see techbrief TB363.

Pin Description

SYMBOL
DESCRIPTION
1
UGATE
The UGATE pin is the upper gate drive output. Connect to gate of the high-side power N-Channel MOSFET.
2
BOOT
BOOT is the 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 Diode” on page 9 for guidance in choosing the appropriate capacitor value.
3
PWM
The PWM signal is the control input for the driver. The PWM signal can enter three distinct states during operation. See
“Three-State PWM Input” on page 9 for further details. Connect this pin to the PWM output of the controller.
4
GND
GND is the ground pin for the IC.
5
LGATE
LGATE is the lower gate drive output. Connect to gate of the low-side power N-Channel MOSFET.
6
VCC
Connect the VCC pin to a +5V bias supply. Place a high quality bypass capacitor from this pin to GND.
7
FCCM
The FCCM pin enables or disables Diode Emulation. When FCCM is LOW, diode emulation is allowed. Otherwise,
continuous conduction mode is forced. See “Diode Emulation” on page 9 for more detail.
8
PHASE
Connect the PHASE 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 driver.
