IR’s New 600V High-Voltage ICs Integrate Host Of Protection Features
International Rectifier (IR)® introduced a set of next-generation 600V high-voltage integrated circuits (HVIC). This IRS212x family of 600V 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 utilizing MOS-gated power devices.
"International Rectifier’s IRS212x family of high-voltage ICs provide a comprehensive set of integrated protection features, including over-current detection at the power switch, while delivering a rugged and reliable solution in a very compact eight-pin footprint," said David New, IR HVIC Product Manager.
The IRS212x family of ICs provides a gate voltage up to 20V, a typical turn-on current of 290mA, a typical turn-off current of 600mA, and accept input logic levels of 3.3, 5, and 15V. Integrated protection features include under-voltage lockout protection, over-current detection and protection, and fault reporting. The new ICs utilize 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 what is described as superior electrical over-stress protection and higher field reliability.
All G5 HVICs have passed extensive quality and reliability testing. Long-term reliability testing was performed to validate robustness beyond the expected useful lifetime of products in certain application environments. This qualification required the devices pass several stress conditions including a 2000 hour, high-temperature biased test.
Additionally, the devices benefit from improvements in reliability due to silicon technology and packaging enhancements. The advanced packaging equipment and materials, for example, combined with recent advancements in mold-compound injection techniques, allow these devices to be less sensitive to moisture and provide improvements in the plastic-to-die interface, an important consideration as peak soldering temperatures have increased with the adoption of lead-free soldering materials. 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 and comply with International Rectifier’s environmental goals and policy.
Pricing for the new IRS212x family of ICs begins at US $0.79 each in quantities of 100,000 units. Production quantities are available immediately.
