DESCRIPTION
PT2432 is an integrated 12V (PT2432A: 24V) 3- phase sensor-less BLDC motor driver with advanced protections including soft-start circuitry, thermal shutdown, lock protection and output current limit. PT2432 is well -suited for sensorless motor applications and ideal for fan motor control requiring high power efficiency. The speed control interface supports both PWM and DC command allowing smooth low speed to high speed motor control. PT2432 requires few peripheral devices, enabling compact PCB layout.
