APEK4915MET-01-T DK: 30A, 3-PH BLDC, 5 ~ 50V in

Summary

Allegro MicroSystems, LLC introduces a new product evaluation kit for their A4915 three-phase MOSFET controller IC to assist customers during the design process. With on-chip hall commutation and a unique SPEED control input, spinning a motor with Allegro’s A4915 couldn’t be easier. The SPEED input takes an analog voltage and generates pulse width modulated (PWM) output with variable duty cycle. 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. Allegro’s solution reduces PCB space by 75% over existing competitive solutions on the market today.

The A4915 evaluation kit is fully compliant to 50V 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 A4915 can be to control a BLDC motor with a simple analog voltage or direct PWM. Six all N-channel power MOSFETs are mounted on the evaluation kit and can supply 30A peak and 20A nominal run current at room temperature. If larger loads are needed the A4915 has jumpers that disable the onboard bridge and provide connections to add an external bridge. Another feature on the evaluation board, which makes operation and evaluation simple, is the onboard 5V regulator which creates the secondary supply for logic inputs.

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 and ATM machines and household appliances.
