International Rectifier Announces New 500V and 600V ICs
International Rectifier Corp. (IR)® introduced a series of next-generation 500 and 600V high-voltage integrated circuits (HVIC). 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, fixed or programmable deadtime for half-bridge drivers, and drive currents up to 2.5A. The new ICs utilize 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 electrical over-stress protection and high field reliability.
"International Rectifier continues to set the standard in high-voltage IC technology. IR's HVICs provide the required design features in a compact, rugged integrated circuit 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.
The 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 whereby the device's junction temperature exceeded datasheet specifications.
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. All new HVICs are qualified to the J-STD-020C standard and comply with IR's environmental goals and policy.
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, 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 High-Voltage ICs begin at US $1.00 each in 10,000-unit quantities. Production quantities are available immediately. The devices are RoHS compliant and prices are subject to change.
