MC33030
DC Servo Motor
Controller/Driver
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 overcurrent monitor and shutdown delay, and
overvoltage 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.
Features
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 Overcurrent Detector
