DESCRIPTION
The SA50CE is a pulse width modulation amplifier that can
continuously supply 5A to the load. The full bridge amplifier
can be operated over a wide range of supply voltages. All of
the drive/control circuitry for the lowside and high side switches
are internal to the hybrid. The PWM circuitry is internal as
well, leaving the user to only provide an analog signal for the
motor speed and direction, or audio signal for switchmode
audio amplification. The SA50CE is packaged in a space
efficient isolated 8-pin TO-3 that can be directly connected
to a heatsink.
