Apex Microtechnology SA60 Low Cost Complete H-Bridge PWM Amplifier
Apex Microtechnology SA60 Low-Cost Complete H-Bridge PWM Amplifier can supply 10A of continuous current to a load. The SA60 is a full-bridge amplifier that is operated over a wide range of supply voltages. All of the drive/control circuitry for the low- and high-side switches are internal to the hybrid. The PWM circuitry is internal and only needs an analog signal for the motor speed/direction, or audio signal for switchmode audio amplification. The internal PWM frequency can be programmed by an external integrator capacitor. An external TTL-compatible PWM signal for simultaneous amplitude and direction control for four-quadrant mode can be provided.
