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. Applications:
