International Rectifier (IR) has introduced a series of single-channel high-voltage integrated circuits (HVIC) for applications including motor control, lighting, switch mode power supplies, industrial and welding and solar panel battery chargers.

Robust, reliable performance
Compared to optocouplers, the IRS2117/8 family of 600V high-side single-channel driver ICs provide lower input current of 40?A and an output signal of 0 to 15V to reduce part count and simplify circuit design. The devices' lower quiescent current of 340?A, undervoltage lockout feature and maximum junction temperature of 150C enable more robust and reliable performance. Additionally, the IRS2117 and IRS2118 feature common mode rejection of 50V/ns.

Proprietary latch immune CMOS technologies enable rugged monolithic construction. The output driver, which is logic input compatible with standard CMOS outputs, features a high-pulse current buffer stage designed for minimum cross-conduction. The floating channel can be used to drive an n-channel power MOSFET or IGBT in the high-side or low-side configuration, operating up to 600V.

Advance HVIC process
The devices use IR's advanced HVIC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver a high level of electrical overstress protection and field reliability.

Pricing for the IRS2117/8 PbF, SPbF and STRPbF begins at 95 cents each in 10,000-unit quantities. Production orders are available immediately. The devices are RoHS-compliant and prices are subject to change.
