DESCRIPTION:

The MSK4206 is a complete H-Bridge microcircuit intended for use in DC brushed motor control applications or

Class D switchmode amplification in severe operating conditions. All of the control circuitry, including an error amplifier,

is internal to the device. A precision reference output is provided for use in offsetting the error amplifier. Fixed highside current

limit is provided internally. Lowside current limit is user controlled with the use of an external resistor network. The design is

packaged in a 10 pin bolt down power package.
