Mikroelektronika MIKROE-3032 Brushless 5 Click BLDC Motor Controller A4941

Technical description of the product (MIKROE-3032):

Brushless 5 Click is a 3 phase sensorless BLDC motor controller, with a soft-switching feature for reduced motor noise and EMI, and precise BEMF motor sensing, which eliminates the need for Hall-sensors in motor applications. It can drive 5V-16V motors with up to 500 mA current. The motor driver allows speed control via the PWM signal from the host MCU. It also features an output pin for reading the speed of the motor. Delayed phase commutation ensures a reliable motor start, while the Lock Detect function prevents damage and overheating. Type: DC. Applications: Ideal for driving small 5V to 16V sensorless BLDC motor driving, silent computer cooling fan driving, efficient air ventilation systems, and similar applications that could benefit of having reliable and simple motor driver circuit. On-board modules: A4941, a three-phase sensorless fan driver, from Allegro MicroSystems LLC. Key Features: Overcurrent limiting, thermal protection, rotor lock protection, sensorless operation, low count of additional components required, soft-switching function, edge terminals for an easy connection. Interface: PWM. Input Voltage: 3.3V. Click board size: M (42.9 x 25.4 mm).
