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.
