Integrated BLDC Motor Drivers


PT2432

PT2432 is an integrated 3-phase sensorless brushless DC motor driver. Including soft start circuit, over temperature protection, lock on protection and current limit protection. PT2432 is very suitable for sensorless motor applications and ideal for fan motor control requiring high efficiency. The speed control interface (VSP) can support PWM and DC commands, allowing for smooth low-speed to high-speed motor control. The PT2432 requires only a few peripheral components and can achieve a compact PCB layout.

PT2432 utilizes a multi-power BCD process, only requires a single power supply, and uses HTSSOP16, HTSOP20 packages to achieve excellent power efficiency, making it a perfect solution for for a highly integrated, low-cost, sensorless brushless DC motor system.
