The MC33030 is a monolithic DC servo motor controller providing all active functions necessary for a complete closed loop system. This device consists of an on–chip op amp and window comparator with wide input common–mode range, drive and brake logic with direction memory, Power H–Switch driver capable of 1.0 A, independently programmable over–current monitor and shutdown delay, and over–voltage monitor. This part is ideally suited for almost any servo positioning application that requires sensing of temperature, pressure, light, magnetic flux, or any other means that can be converted to a voltage.

Although this device is primarily intended for servo applications, it can be used as a switchmode motor controller.

• On–Chip Error Amp for Feedback Monitoring

• Window Detector with Deadband and Self Centering Reference Input

• Drive/Brake Logic with Direction Memory

• 1.0 A Power H–Switch

• Programmable Over–Current Detector

• Programmable Over–Current Shutdown Delay

• Over–Voltage Shutdown
