Description
The FAN7316 is a LCD backlight inverter drive IC that
controls N-N half-bridge topology. The FAN7316 can also
drive push-pull topology.
The FAN7316 provides a low-cost solution by integrating
the external open-lamp protection circuit. The operating
voltage of the FAN7316 is wide, so the FAN7316 doesn’t
need an external regulator to supply the voltage to the IC.
The FAN7316 has the internal bootstrap driver, so the
external fast recovery diode can be avoided.
The FAN7316 provides various protections, such as
open-lamp regulation, arc protection, open-lamp
protection, short-circuit protection, and CMP-high
protection to increase the system reliability. The
FAN7316 provides analog dimming, burst dimming, and
burst dimming polarity selection functions.
The FAN7316 is available in a 20-SOIC package.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In
addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Recommended Operating Ratings
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
