1. Refer to TB347 for details about reel specifications.

2. These 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).

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), refer to the ISL6596 product information page. For more information about MSL, see TB363.

Functional Pin Descriptions

PIN NUMBER (Note 4)PIN NAME

DESCRIPTION

1

UGATE

Upper gate drive output. Connect to the gate of the high-side N-Channel power MOSFET. A gate resistor

is never recommended on this pin because it interferes with the operation shoot-through protection

circuitry.

2

BOOT

Floating bootstrap supply pin for the upper gate drive. Connect a bootstrap capacitor between this pin

and the PHASE pin. The bootstrap capacitor provides the charge used to turn on the upper MOSFET.

See “Bootstrap Considerations” on page 7 for information about choosing the appropriate capacitor

value.

3, 8

N/C

Do not connect.

4

PWM

Driver control input. The PWM signal can enter three distinct states during operation. See “PWM Input and

Threshold Control” on page 7 for more information. Connect this pin to the controller PWM output.

5

GND

Ground pin. All signals are referenced to this node.

6

LGATE

Lower gate drive output. Connect to the gate of the low side N-Channel power MOSFET. A gate resistor

is never recommended on this pin because it interferes with the operation shoot-through protection

circuitry.

7

VCC

Connect this pin to a +5V bias supply. Bypass locally to ground with a high quality ceramic capacitor.
