600 V HVICs integrate host of protection features

14 November 2007 Power Electronics / Power Management

International Rectifier has introduced a set of next-generation 600 V high-voltage integrated circuits (HVICs). The IRS212x family of single-channel gate drivers is suitable for motor control applications at low-, mid- and high-voltage levels and in a variety of circuit topologies including three-phase inverter, H-bridge, and other topologies utilising MOS-gated power devices. This family provides a gate voltage up to 20 V, a typical turn-on current of 290 mA, a typical turn-off current of 600 mA, and accept input logic levels of 3,3 V, 5 V and 15 V. Integrated protection features include under-voltage lockout protection, over-current detection and protection, and fault reporting. The surface mount SO-8 packages are qualified to MSL2 (moisture sensitivity level 2) while all other surface mount packages are MSL3 qualified. In addition, the new HVICs are qualified to the J-STD-020C standard.
