µHVI power circuit building blocks simplify design

November 28, 2014 // By Graham Prophet
International Rectifier has introduced the µHVIC family of general purpose high-voltage and low-voltage integrated circuits that simplifies power system development by offering easy-to-implement building blocks for frequently used circuit elements.

These µHVIC devices include the IRSxx752L 100V, 200V and 600V single channel high-side drivers; the IRS25751L high-voltage start-up IC; the IRS44273L single channel low-side driver IC; the IRS2505L PFC boost driver IC; and the IR25750L current sensing IC.

µHVIC family is a tool kit of ICs for common circuit elements in switched mode power (SMPS) electronics, that offers engineers simple, flexible ICs with which to conveniently design and innovate. The µHVIC family uses IR's high-voltage IC technology to realise multiple functions and integrate robust protective features. The family is available in a small 5 lead or 6 lead SOT23 package.

Featuring integrated ESD and excellent latch immunity to enable rugged monolithic protection, IR’s µHVI family is qualified to industrial grade, RoHS compliant and moisture sensitivity level 1 (MSL1).
