BLDC MOTOR CONTROL EVALUATION KIT
ATAVRMC100
The ATAVRMC100 BLDC motor control kit is an evaluation tool and development
board for the AT90PWM3B AVR microcontroller from Atmel.
The board includes power bridges for BLDC motors and can realize zero crossing
voltage detection, hardware overcurrent detection and motor supply voltage
measurement. An on board LIN transceiv-
er allows to drive application through a
LIN network. Programming of the code
into the microcontroller's Flash memory
can be performed with an AVRISP or a
JTAGICE mkII through the dedicated con-
nectors.
Power Bridge for BLDC Motors
OAny commutation schemes are possible.
ORecommended Voltage Operation from 8 to
16V DC (4A)
