DESCRIPTION

The SA01 amplifier is a pulse width modulation amplifier that

can supply 2KW to the load. The full bridge output amplifier

can be operated from a single power supply over a wide range

of voltages. An error amplifier is included which can provide

gain for the velocity control loop in brush type motor control

applications.Current limit is programmable by a single resistor.

A shutdown input turns off all four drivers of the H bridge output.

A precision reference output is provided for use in offsetting

the error amplifier. The error amplifier can then be scaled for

standard input signals.The amplifier is protected from shorts to

supply or ground.The H bridge output MOSFETs are protected

from thermal overloads by directly sensing the temperature of

the die. The 10-pin hermetic power package occupies only 2

square inches of board space and is isolated.
