600V single-channel ICs simplify circuit design
Keywords:HVIC International Rectifier motor control solar panel battery chargers IRS2117
International Rectifier (IR) has introduced a series of robust single-channel high-voltage integrated circuits (HVIC) for a wide range of applications including motor control, lighting, switch mode power supplies, industrial and welding and solar panel battery chargers.
Compared to optocouplers, the IRS2117/8 family of 600V high-side single-channel driver ICs provide lower input current of 40µA and an output signal of 0 to 15V to reduce part count and simplify circuit design. The devices' lower quiescent current of 340µA, under-voltage lockout feature and maximum junction temperature of 150°C 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.
The devices utilise IR's advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.
Pricing for the IRS2117/8 PbF, SPbF and STRPbF begins at Rs.43.05 (95 cents) each in 10,000-unit quantities. Production orders are available immediately. The devices are RoHS compliant and prices are subject to change.
