International Rectifier has introduced a series of 500 V and 600 V 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. These ICs are offered with single or dual inputs, undervoltage lockout protection, fixed or programmable deadtime for half-bridge drivers and drive currents up to 2.5 amperes.

These ICs use a high-voltage IC process, known as G5 HVIC, that enables a number of new features. A next-generation, high-voltage level-shifting and termination technology delivers superior electrical over-stress protection and higher field reliability.

International Rectifier's HVIC technology integrates n-channel and p-channel LDMOS circuitry in an intelligent driver IC. The ICs can be driven by low-voltage inputs and provide gate drive and protection features for HV power-conditioning applications. Also, 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 that eliminates the need for a large and expensive auxiliary power supply that discrete optocoupler- and transformer-based designs typically have required in the past.

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. Pricing for the HVICs begin at U.S. $1.00 each in 10,000-unit quantities. Production quantities are available immediately; the devices are RoHS compliant.
