The SA56 is a 5-ampere PWM Amplifier 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.

Applications:

  • DC Brush-Type and Stepper Motor Drives
  • Position and Velocity Servomechanisms
  • Factory Automation Robots
  • Numerically Controlled Machinery
  • Computer Printers and Plotters
  • Audio Amplification

  • Delivers up to 5A Continuous Output
  • Operates at Supply Voltages up to 60V
  • TTL and CMOS Compatible Inputs
  • No “Shoot-Through” Current
  • Thermal Shutdown (Outputs Off) At 160°C
  • Shorted Load Protection (to VS or PGND or Shorted Load)
  • No Bootstrap Capacitors Required
  • Programmable Onboard PWM
