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.
