SA57A - Switching Amplifier

General Description

The SA57A is a fully integrated switching amplifier designed primarily to drive DC brush motors.

Two independent half bridges provide over 15 amperes peak output current under microcontroller or DSC control.

Key Features

  • Low cost intelligent switching amplifier.
  • Directly connects to most embedded Micro- controllers and Digital Signal Controllers.
  • Integrated gate driver logic with dead-time generation and shoot-through prevention.
  • Wide power supply range (8.5V to 60V).
  • Over 15A peak output current per phase.
  • Independent current sensing for each output.
  • User programmable cycle-by-cycle current limit protection.
  • Over-current and over-t.
