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.
