FUNCTION
High-Side MOSFET NH1 Gate-Driver Output
Low-Side MOSFET NL1 Gate-Driver Output
Low-Side MOSFET NL2 Gate-Driver Output
Power Ground. PGND is the return for the GL1 and GL2 gate drivers.
Low-Side Gate-Driver Supply Input. Connect V
DD
to the output of the internal linear regulator (V
CC
). Bypass
V
DD
with a 0.1μF capacitor to PGND.

5.3V/10mA Internal Linear-Regulator Output. V
CC
is the supply voltage for the device. Bypass V
CC
with a
1μF ceramic capacitor to GND.

GND
Analog Ground. The ground return for V
CC
, REF, and other analog circuitry. Connect GND to PGND under
the IC at the IC’s backside exposed metal pad.
