DESCRIPTION

· The FAN7532 is a high-performance electronic ballast control IC designed for driving two power MOSFETs in a half-bridge topology.
· It simplifies electronic ballast design by minimizing board area and reducing component count.
· It includes comprehensive protection features for filament failure, lamp strike failure, and automatic restart.
· A dedicated timing section allows precise control of preheat, ignition, and lamp operation.

FEATURES

· Floating channel supports bootstrap operation up to +600V.
· Lower di/dt gate driver enhances noise immunity.
· Driver current capability: 250mA/500mA (Typ.).
· Low start-up and operating current: 120µA, 6.4mA.
· Under-voltage lockout (UVLO) with 1.8V hysteresis.
· Programmable preheat time, run frequency, and lamp filament sensing.
· High-accuracy oscillator and 16-pin SOP package.

APPLICATIONS

· General-purpose electronic ballast control.
