5A, 60V PWM Amplifier ICThe 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.
