PIN DESCRIPTION

PIN NUMBER

NAME

FUNCTION

1

ZCD_EN#

The ZCD_EN# pin enables or disables Diode Emulation. When ZCD_EN# is LOW, diode

emulation is allowed. When ZCD_EN# is HIGH, continuous conduction mode is forced.

ZCD_EN# can also be put in a high impedance mode by floating the pin. If both ZCD_EN#

and PWM are floating, the device shuts down and consumes typically 3 μA (9 μA max.)

current.

2VCIN

Supply voltage for internal logic circuitry

23

CGND

Analog ground for the driver IC

3N.C.

This pin can be either left floating or connected to CGND.

Internally it is either connected to GND or not internally

connected depending on manufacturing location.

Factory code “G” on line 3, pin 3 = CGND

Factory code “T” on line 3, pin 3 = not internally connected

4

BOOT

High-side driver bootstrap voltage

5

PHASE

Return path of high-side gate driver

6 to 8, 25

VIN

Power stage input voltage. Drain of high-side MOSFET

9 to 11, 17, 18, 20, 26

PGND

Power ground

12 to 16

VSWH

Switch node of the power stage

19, 24

GL

Low-side gate signal

21

VDRV

Supply voltage for internal gate driver

22

PWM

PWM control input
