Allegro MicroSystems A8932CLWA

A8932CLWA is a full-bridge driver that can be configured so that its output current is a direct function of an externally applied control voltage or current. This linear current control function is supplemented by additional circuitry to protect the heads and the data disk during system failure or normal system shutdown. The two ±500 mA MOS driver outputs provide very low saturation voltage and minimal power dissipation.
