DESCRIPTION The cLS-FSTS-MC2-5 utilizes an  MC33932.  This is a monolithic H-bridge  in a tough thermal package.  The board  also includes inputs from pulse sensors  used for motor RPM.  All I/O is routed  through a jumper selection connector  prior to the Tower System interface.  This  allows for the routing to one of two  possible resources per interface point.   Motor speed is controlled via two PWM  pulses per motor; the PWMs have a  maximum frequency of 11KHz.  The pulse  sensors inputs are not required for the  module to function.  Each motor channel  has an analog low-side current sense  available for the Tower system CPU card.  Board ships with full schematics and code  sample.  Also included is an excel  spreadsheet to be included with the  Freescale Tower Configuration Tool.  PERFORMANCE H-bridge outputs: 4 Outputs RDS_ON: 120mΩ PWM: 11 KHz ESD: 2 KV Control/communication: Discrete Operating current: 5A continuous, package is heat sinked to the ground plane SPECIFICATIONS Interface: Selectable as required to conform to Tower System. Plug-in screw terminals for motor and motor power connection. Physical Characteristics: Freescale Tower System Format Power Requirements: Supply Voltage (Typical) 3.3V or 5.0V (5.5V maximum) Motor Supply Voltage 8VDC - 28VDC Current (Typical) TBA Motor Current 5A per motor maximum Environmental Characteristics: Operating Temperature: -20⁰C to 90⁰C Storage Temperature: -40⁰C to 105⁰C Relative Humidity: 0 to 90% non-Condensing MODEL NUMBERS cLS-FSTS-MC2-5: Dual channel motor card c-Link Systems, Inc.
