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.
