IRS2158D(S)
Description
The IRS2158D is a fully integrated, fully protected 600V ballast control IC designed to drive all types of
fluorescent lamps. The IRS2158D features include programmable preheat and run frequencies,
programmable preheat time, closed-loop half-bridge ignition current regulation, programmable end-of-life
protection, brownout protection and low input offset op amp. The op amp can be used for dimming, current
or power control. Comprehensive protection features such as protection from failure of a lamp to strike,
filament failures, end-of-life protection, have been included in the design. The IRS2158D is available in both
16-pin PDIP and 16-pin narrow body SOIC packages.

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 zener clamp structure between the chip VCC and COM which has a nominal
breakdown voltage of 15.6V. This supply pin should not be driven by a DC, low impedance power
source greater than the VCLAMP specified in the Electrical Characteristics section.
