COMPOSITE MODULES, INC. COMPOSITE MODULES, INC. Typical Uses: Designed with the user in mind, this plug and play module requires a single +22.0 to +48.0 Volt power supply to operate a 3 Phase DC Brushless Motor. Fig 2 illustrates a typical application using the CMI 5015-48 Controller. Three 15 Volt CMOS compatible open collector hall devices are required for commutation. The internal +15.0 Volt Reference is capable of supplying up to 100mA and is more than adequate for the Hall devices and additional driver circuitry. Care should be taken in connecting the Analog ground (pin 9) and should only be used as low current reference. Although connected internally this pin cannot handle excessive current. A 10F Low ESR Bus Capacitor is provided internally and should be adequate for most applications, however, at user discretion additional capacitance can be added externally when bus leads are highly inductive. Mechanically the unit should be mounted to a heat sink using either silicon grease or a thermal pad. Recommended hardware are #6 Washers and 6-32 / 6-40 socket head cap screws tightened to a minimum of 30 in-lbs. of torque. Packaged in a miniature hermetic module, this device is ideally suited for high performance 3-Phase Brushless Motor Control Applications. Among the many applications are: Robotics, electromechanical valve assemblies, battery operated motors, fans and blowers, cryogenic coolers, and battery operated vehicles. The CMI 5015-48 operates over the temperature of -55C and +125C. Custom designs are available upon request. 48 CMI 5015-48 Application Notes: GND Vm S S N +12.0 Volts 50 K Ohm Speed (1) cw/ccw +V cc HA HB HC N/C Signal Ground Single Supply Operation Low Loss Current Sensing Under Voltage Lockout Automatic Brake Actuation 100 mA +15 Volt Reference Forward / Reverse Control Thermal Shutdown Internal Bus Capacitor -55C to +125C Operation The CMI 5015-48 motor control module is specifically designed for operating both fractional and integral horsepower motors. This unique module operates from a single input supply ranging from +22 to +48 Volts with output capabilities up to 12 Amps continuous current and peak currents of 24 Amps. Housed in a metal hermetic package this module is applicable to a wide range of environmental usages. Designed with the user in mind this plug and play module is easy to use. The circuit uses the latest in ASIC technology for commutation, cross conduction protection, automatic braking, under voltage lockout and cycle-bycycle current limiting. It also contains a temperature CMI 5015-48 +Vm CMI compensated voltage reference. The high efficiency "N" Channel MOSFET output stage, driven with a custom high side driver, allows true low to zero speed operation without the loss of the high side voltages. A unique low loss current sensing circuit and an internal bus capacitor eliminate the need for large external components. The CMI 5015-48 incorporates an internal reference that allows the module to operate off a single supply as low as +22 Volts while supplying the maximum current to the output stage. Standard electrical sensor phasing is 60 with a factory wiring option of 120.
