Gate Drive ICs Offer up to 85% Smaller Footprint

International Rectifier (IR) has announced the extension of its packaging portfolio with the introduction of a PQFN 4x4mm package featuring IR's latest high-voltage gate drive ICs that delivers an ultra-compact, high density and efficient solution for a wide variety of applications including home appliances, industrial automation, power tools and alternative energy.

Featuring a footprint of just 16mm⊃2, the new PQFN4x4 (modified MLPQ 16-lead) package can accommodate many of IR's high performance high-voltage gate drive ICs that previously required packages as large as the wide-body SOIC-16, offering up to an 85 percent smaller footprint. The new package has been designed with the appropriate creepage and clearance requirements to enable rugged and reliable designs at voltages up to 600V.

With a low profile of less than 1mm, the PQFN4x4 package is compatible with existing surface mount techniques, is MSL2 rated and RoHS compliant.

International Rectifier'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.
