CoreControl TM Data Sheet TDA21106
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 to be compatible to TDA21101G and HIP6601B. In addition it provides
protection features as well as a three-state 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.
