SA57A

SA57A SAS5A75A7A Switching Amplifier 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-temperature warning signals APPLICATIONS ♦ Bidirectional DC brush motors ♦ 2 unidirectional DC brush motors ♦ 2 independent solenoid actuators ♦ Stepper motors 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. Thermal and short circuit monitoring is provided, which generates fault signals for the microcontroller to ...
