DESCRIPTION:
The MSK4226 is a complete H-Bridge circuit to be used for DC brushed motor control or Class D switchmode amplifi-
cation. All of the drive/control circuitry for the lowside and highside switches are internal to the circuit. Logic level inputs are
provided for controlling each MOSFET independently, allowing every possible switch combination except those that would
cause a simultaneous conduction or shoot-through condition for each half bridge. This gives the user freedom to use various
modulation schemes for PWM control. The MSK4226 is constructed in a space efficient plastic power package that can be
directly bolted to a heatsink.
