Apex Microtechnology SA57 PWM Amplifier with Integrated Gate Driver

Apex Microtechnology SA57 PWM Amplifier with Integrated Gate Driver delivers up to 17A of output current for driving brush-type DC motors. The SA57AHU allows for a seamless digital interface by partnering with either an MCU or DSP. Individual control of the top and bottom side output FETs are allowed via direct signals from the processor. Thermal and short circuit monitoring for the SA57 is provided, which generates fault signals for the microcontroller to take appropriate action. Additionally, the cycle-by-cycle current limit offers user-programmable hardware protection independent of the microcontroller.
