5A, 60V PWM Amplifier IC

The SA56 is a 5-ampere PWM Ampliier designed for motion control applications. The device is built using a multi-technology process that combines bipolar and CMOS control circuitry with DMOS power devices in a single monolithic structure. Ideal for driving DC and stepper motors, the SA56 accommodates peak output currents up to 10 amperes. An innovative circuit that facilitates low-loss sensing of the output current has been implemented. An on-board PWM Oscillator and Comparator are used to convert an Analog signal into PWM direction of rotation and magnitude for Motor Control applications. TTL or CMOS digital inputs allow direct external control in 2-quadrant or 4-quadrant modes. By Cirrus Logic, Inc.
