PT2522 - Sensor-less BLDC Controller

Description

The PT2522 is a three-phase, sensor-less brushless DC motor control driver chip.

The three-phase control is based on a square /trapezoidal wave control method that detects the zero-crossing of the motor back electromotive force (BEMF).

Features

  • Sensor-less three-phase brushless DC motor control driver chip.
  • Integrated three 90V half-bridge gate drivers.
  • Driver pull-out/inrush current: 1200mA/2000mA.
  • Built-in +5V LDO, 5V ~ 24V power supply.
  • OTP burning motor control parameters.
  • Set OTP parameters through I2C.
  • Current limit and overvoltage protection.
  • Temperature protection function (using external NTC resistor).
  • Stall protection function.
  • PWM or DC input speed control.
  • FG s.

DESCRIPTION The PT2522 is a three-phase, sensor-less brushless DC motor control driver chip. The three-phase control is based on a square /trapezoidal wave control method that detects the zero-crossing of the motor back electromotive force (BEMF). It has a stable control and is not be affected by motor easily differences. The chip's soft-switching technology can achieve ladder or sinusoidal current waveforms, further reducing phase electromagnetic noise. The on-chip + 5V LDO provides operational operation for both logic and analog circuitry. It also integrates three 90V halfbridge gate drivers, making it ideal for gate drive of high-speed power MOSFETs and IGBTs in three-phase motor applications.
