International Rectifier's next-gen HVICs

International Rectifier (IR) has introduced a series of next-generation 500V and 600V high-voltage integrated circuits (HVIC). The company said these 19 new HVICs, half-bridge and high- and low-side drivers address a wide range of applications including motor control, lighting, switch-mode power supplies, audio and flat-panel displays. They are offered with single or dual inputs, under-voltage lockout protection and fixed or programmable deadtime for half-bridge drivers. The new devices drive currents up to 2.5A.

According to IR, the new ICs use an advanced high-voltage IC process, known as G5 HVIC, which enables a host of new features and enhancements. A next-generation high-voltage level-shifting and termination technology delivers superior electrical over-stress protection and higher field reliability, the company said.

Reability testing
The G5 HVICs have passed extensive quality and reliability testing to ensure robustness beyond the expected useful lifetime in certain application environments. The devices' advanced packaging equipment and materials, 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, which according to IR is an important consideration as peak soldering temperatures have increased with the adoption of Pb-free soldering materials. The surface mount SO-8 packages of the new devices are qualified to MSL2 while all other surface mount packages are MSL3 qualified.

"IR's HVICs provide the required design features in a compact, rugged IC that helps reduce design time, development risk, footprint, and system cost while improving reliability and time-to-market for the user's end products," said David New, IR product manager.

Integrated device
IR's HVIC technology integrates n-channel and p-channel LDMOS circuitry in an intelligent driver IC. The ICs receive a low-voltage input and provide gate drive and protection features for HV power-conditioning applications. Additionally, IR said these monolithic HVICs provide integration of features and functionality to simplify circuit design and reduce overall cost, including the option to use a low-cost bootstrap power supply, which eliminates the need for the large and expensive auxiliary power supply that discrete optocoupler- or transformer-based designs typically require.

Pricing for the new HVICs begin at $1 each in 10,000-unit quantities. Production quantities are available immediately. The devices are RoHS compliant and prices are subject to change.
