Optical Encoder Inputs

•Inputs for two Quadrature Optical Encoders

•up to 250khz Encoder frequency per channel

•two 32-bit up-down counters

•Inputs may be shared with four optional limit switches per channel

Internal Sensors

•Voltage sensor for monitoring the main 12 to 40V battery system operation

•Voltage monitoring of internal 12V

•Temperature sensors on the heat sink of each power output stage

•Sensor information readable via RS232 port

Low Power Consumption

•On board DC/DC converter for single 12 to 40V battery system operation

•Optional backup power input for powering safely the controller if the motor batteries are discharged

•Max 200mA at 12V or 100mA at 24V idle current consumption

•Power Control wire for turning On or Off the controller from external microcomputer or switch

•No power consumed by output stage when motors are stopped

•Regulated 5V output for powering R/C radio. Eliminates the need for separate R/C battery

High Efficiency Motor Power Outputs

•Two independent power output stages

•Optional Single Channel operation at double the current

•Dual H bridge for full forward/reverse operation

•Ultra-efficient 2.5mOhm ON resistance (RDSon) MOSFET transistors

•Synchronous Rectification H Bridge

•12 to 40 V operation

•High current Fast-on power connection tabs for power stage

•Temperature-based Automatic Current Limitation
