Intersil's High Current MOSFET Gate Drivers Provide Industry's Best Switching Efficiency

ISL6615, ISL6615A Reduce Gate Voltage Rise and Fall Times to Minimize Switching Loss, Increase Efficiency and Provide Advanced Fault Protection Without a Board Redesign

MILPITAS, CA--(Marketwire - May 13, 2008) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced the release of the ISL6615 and ISL6615A. These high-frequency 6A sink synchronous MOSFET gate drivers provide greater efficiency, dramatic flexibility and added protection features for system safety.

The new drivers have increased gate drive currents (4A source and sink gate drive currents for UGATE and 4A source with 6A sink on LGATE) to reduce gate voltage rise and fall times. This minimizes switching losses and improves efficiency, especially in high current applications in which power MOSFETs are placed in parallel per phase.

The ISL6615 and ISL6615A also support both 9.6V and 12V input rails. In addition, designers can choose versions of the device which support 3.3 PWM signals (ISL6615) or 5V PWM signals (ISL6615A). Each device has a wide input voltage operating range of 5V to 12V and each is pin-for-pin compatible with Intersil's previous generation ISL6594D.

With multiple protection features like bootstrap capacitor overcharging prevention, a tri-state PWM input for safe output stage shutdown, pre-POR overvoltage protection and VCC undervoltage protection, the ISL6615 and ISL6615A help protect the system.

This attention to system safety, combined with improved flexibility and greater gate drive efficiency, allows designers to remain consistent in board design, while creating improvements and avoiding the use of expensive, low RDS(ON) MOSFETS.

Pricing and Availability

The ISL6615/15A are available now in 8-lead SOIC packages priced at $1.67 each in 1,000 unit quantities and in 10-lead DFN packages priced at $1.69 in 1,000-unit quantities.
