Motor-control module

The CMI-5015-28 motor-control module from Composite Modules Inc.

The CMI-5015-28 motor-control module from Composite Modules Inc., Attleboro, Mass., operates fractional and integral horsepower motors. The unit operates from a single input supply ranging from 14 to 35 V with output capabilities up to 20 A. It is housed in a metal hermetic package and can be used for robotics, electromechanical-valve assemblies, battery-operated motors, fans and blowers, cryogenic cool-ers, and low-voltage, battery-operated vehicles. The circuit uses ASIC technology for commutation, cross-conduction protection, automatic breaking, undervoltage lockout, and cycle-by-cycle current limiting. The N Channel MOSFET output stage is driven with a custom high side for low to zero-speed operation without the loss of high-side voltages. A low-loss current sensing circuit and internal bus capacitor eliminate the need for large external components. An internal reference lets the module operate off a single supply as low as 16 V while supplying maximum current to the output stage. Operating temperature is 55 to 125°C.
