PT2434 Datasheet (PTC) - 3-Phase Sensorless BLDC Motor Controller

PT2434, 3-Phase Sensorless BLDC Motor Controller

The PT2434 is a three-phase, sensor-less, brushless DC motor control chip.

System operating voltage depends on the VM (motor voltage), from 12V to 400Vdc.

On-chip LDO can provide 5V voltage for logic and analog circuits operation.

The three-phase sensor-less control is based on trapezoid wave, and a
