DESCRIPTION:
The MSK 4203 is a complete H-Bridge hybrid intended for use in DC brushed motor control applications or Class D
switchmode amplification. All of the drive/control circuitry for the lowside and highside switches are internal to the hybrid,
as well as a +5V linear regulator. The PWM circuitry is internal as well, leaving the user to only provide an analog signal
for the motor speed/direction, or audio signal for switchmode audio amplification. The MSK 4203 is packaged in a space
efficient isolated 18 pin power package available in three lead form configurations that can be directly connected to a
heatsink.
