Faults are indicated by a single open drain output than can be used to pull the PWM input low.

Several operational modes are available including nldc voltage control, current torque limit control and closed loop speed control. Another feature on the evaluation board, which makes operation and evaluation simple, is the onboard 5 V regulator which creates the secondary supply for logic inputs.

Integrated diagnostics provide indication of under voltage, over temperature and power bridge faults and can protect the power switches under most short circuit conditions.

  DELL MODEL 1905FP DRIVER

This innovative control interface combined with on-chip hall commutation makes it possible to efficiently control a BLDC motor with little or no micro processing power.

If larger loads are needed the A has jumpers that disable the onboard bridge and provide connections to add an external bridge.

The sensorless start-up scheme allows the A to operate over a wide range of motor and load combinations. Allegro MicroSystems, LLC is a leader in developing, manufacturing and marketing high-performance semiconductors. The A evaluation kit is fully compliant to 50 V and includes everything needed to spin a motor – just provide a voltage supply and a motor and you will be able to see just how simple the A can be to control a BLDC motor with a simple analog voltage or direct PWM.

Allegro MicroSystems – A 3-Phase Brushless DC Motor Pre-Driver

This new development kit is targeted at both the industrial and consumer markets with end applications to include power tools, lawn and garden equipment, pumps, ticketing allegdo ATM machines and household appliances. We’ll notify you when there are updates to this product.

  IMAGE CLASS MF4150 DRIVER

The motor is driven using block commutation trapezoidal drive where phase commutation is determined, without the need for independent position sensors, by monitoring the motor back- EMF bemf. Operating mode and control parameters can be altered through an SPI compatible serial interface. Click the image to view larger.

Motor operation is controlled by a programmable PWM input that can be used to define the motor operating state and provide the proportional input for the selected operating mode. The A can be used as a stand-alone controller communicating directly with an electronic control unit ECU or it can be used in a close coupled system with a local microcontroller MCU.
