200 VOLT 20 AMP MOSFET

H-BRIDGE WITH

GATE DRIVE

4227

The MSK 4227 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 4227 is constructed in a space efficient plastic power package

that can be directly bolted to a heatsink.
