General Description

The dual high speed driver is designed to drive a wide range of N-Channel low side and N-Channel high

side MOSFETs with varying gate charges. It has a small propagation delay from input to output, short

rise and fall times and the same pin configuration as the HIP6602B. In addition it provides several

protection features as well as a shut down mode for efficiency reasons. The high breakdown voltage

makes it suitable for mobile applications.

Target application

The dual high speed driver is designed to work well in half-bridge type circuits where dual N-Channel

MOSFETs are utilized. A circuit designer can fully take advantage of the driver´s capabilities in high-

efficiency, high-density synchronous DC/DC converters that operate at high switching frequencies, e.g.

in multi-phase converters for CPU supplies on motherboards and VRM´s but also in motor drive and

class-D amplifier type applications.
