IRS2552D
Description
The IRS2552D incorporates a high voltage half-bridge gate driver with a front end that incorporates full control
functionality for CCFL/EEFL ballasts. Includes a programmable ignition and supports dimming via analog or PWM
control voltage. HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The
output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise
immunity is achieved with low di/dt peak of the gate drivers, and with an undervoltage lockout hysteresis of
approximately 1 V. The IRS2552D also includes protection features for over-current and over-voltage of the lamps.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.

This IC contains a voltage clamp structure between the chip V
CC
and COM which has a nominal breakdown
voltage of 15.6 V. Please note that this supply pin should not be driven by a DC, low impedance power source
greater than the V
CLAMP
specified in the Electrical Characteristics section.
