Integrated BLDC Motor Drivers


PT2512

The PT2512 is an integrated three-phase sine wave current BLDC motor driver that is driven without Hall sensors. This driver has multiple protection functions, including over-current protection, over-temperature protection, lock protection, etc. PT2512 supports VSP(DC), PWM, Clock input command control. The motor parameters can be adjusted by using the capacitors or resistors on the peripheral pins of the IC to achieve the best performance control, and no software or program recording is required, which can shorten the development and production time. The small QFN16 or DFN10 3x3mm package with few peripheral components enables a compact PCB layout. The typical operating voltage of PT2512 is 5V and can provide a maximum driving current of about 1A, which is suitable for use in 1W ~ 5W motor applications.
