DESCRIPTION
:
The MSK 4221 is a plete H-Bridge circuit to be used for DC brushed motor control or Class D switchmode amplifiers. All of the drive/control circuitry for the lowside and highside switches are included internally. The user provides a digitally patible PWM signal (a reference divider is provided for TTL patability or the user provides their own to the VREF IN) for simultaneous amplitude and direction control in four quadrant mode. The internal drive circuitry will provide proper deadtime/shoot-through protection for each half-bridge. All N-channel FETs mean the best efficiency for the size,...
