BUS IC DC/DC CONVERTER MOTOR DRIVER IC Fan control y EC motor control Steppermotor driver RIPPLE COUNTER DRIVER IC I/O IC SENSOR IC SENSOR INTERFACE IC y EC motor control FEATURES y y y y y y y y y y y y y y y High voltage supply in the range VS = 6.0 V to 58 V Drive of up to 6 external n-channel Power FETs (3 high side- and 3 low side switches) Programmability of functions and parameters by SPI P interface Self adjusting driver timing and power FET protection High power efficiency Low RF emission due to the field programmable driver technology Three current measurement amplifiers and programmable over current protection On chip and external over temperature detection and protection Programmable analog measurement channels (temperature and motor currents) Position detection by BEMF Sleep / Wake up mode system 5V or 3.3V interface to control device Developmentkits available (programmable board and software with PC Interface) - 40C to + 125C operating temperature PLCC68 package The device works in typical motor regulator systems as physical interface between a C or a special controller hardware and the power FET-motor load configuration. The user has the complete control over the logical behaviour by software implementation in the C. In this way all control/regulation strategies of the motor can be realised by software development. DESCRIPTION The IC is a PWM EC brushless motor driver/controller to implement a motor regulator together with n-channel power FET B6configuration and a C The programmability of parameters (e.g. threshold values of over current, over temperature, motor failures, EMC conditions, etc.) can be used to drive motors in a widely different range. These programmability features and the driver channel control inputs and allow this chip to act in general motor regulator applications, too. The special programmable switching technology (pendingpatent) enables an excellent EMC behavior.
