600 V drivers integrate host of protection features

6 February 2008 Power Electronics / Power Management

International Rectifier's new IRS212x family of 600 V 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.

The 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 accepts 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 new ICs utilise an advanced high-voltage IC process platform, known as G5 HVIC, which enables a host of new features and enhancements. A next-generation high-voltage level-shifting and termination technology delivers high electrical over-stress protection and field reliability.

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.
