DESCRIPTION:
The MSK 4226 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 MSK 4226 is constructed in a space efficient plastic power package
that can be directly bolted to a heatsink.
