Introduction

PT2513 is an integrated three-phase sensorless BLDC motor driver with advanced protection features, including soft-start circuit, thermal shutdown, lock protection, and output current limiting. PT2513 is well suited for sensorless motor applications and is an ideal choice for fan motor control requiring high efficiency. The speed control interface supports both PWM and DC (VSP) commands, enabling smooth motor control from low to high speed. PT2513 is fabricated using BCD process technology, operates from a single VDD supply, and requires only a few external components. The device is available in an HTSSOP16 package with an exposed bottom thermal pad, delivering excellent energy efficiency and making it an ideal solution for compact, low-cost, sensorless BLDC motor drives.
