DESCRIPTION
The PT2522 is a three-phase, sensor-lessbrushless DC motor control driver chip. Thethree-phase control is based on a square/trapezoidal wave control method that detects thezero-crossing of the motor back electromotiveforce (BEMF). It has a stable control and is not beaffected by motor easily differences. The chip&＃39;ssoft-switching technology can achieve ladder orsinusoidal current waveforms, further reducingphase electromagnetic noise. The on-chip + 5VLDO provides operational operation for both logicand analog circuitry. It also integrates three 90Vhalf-bridge gate drivers, making it ideal for gatedrive of high-speed power MOSFETs and IGBTsin three-phase motor applications. The PT2522provides a way to change internal parametersettings by burning to optimize different motorsand applications. The package of the PT2522 is LQFP32.
APPLICATION
● Three-phase DC brushless moto
● High speed fan application
● Water pump application
