Overview
The ATA6847 Evaluation Board is fully assembled and tested to evaluate and demonstrate the ATA6847 capabilities. The ATA6847T-5033H/NHX used with dsPIC33CK64MP205 provides the necessary drive signals to drive a 3-Phase BLDC motor.
The board is optimized for input voltages from 4.9V to 32.5V and the firmware pre programmed on the microcontroller is optimized to work with AC300022 - 24V 3-PHASE BRUSHLESS DC MOTOR in sensorless field oriented control.
• Input operating voltage range: 4.9V to 32.5V
• Maximum of 10/27Ω of gate drive sink/source resistance for external N-Channel MOSFETs and programmable LS/HS slew rate control: 12.5%, 25%, 50%, 100%
• Drives up to a 35A RMS BLDC motor
• Two programmable gain/offset current sense amplifiers
• ON/OFF push button (RUN)
• Reset push button (RST)
• Spare user-programmable push button (µC/Wk)
• PWM signal LED indicators
• Fault signal LED indicator
• Wake-up push button
• PICkit™ debugger interface
• Speed control potentiometer
• Terminal block for 3.3V and 5V Hall-effect sensors
• UVLO, OVLO and DUVLO protections
• Programmable external MOSFET short circuit protection 125 mV to 1.75V
• Programmable PWM dead-time protection 100 ns to 6.3 µs (100 ns step)
• Thermal shutdown protection
• Programmable timing filters for current and voltages
• Complete “C” source code (provided on the Motor Driver Evaluation Board webpage).
