PT2501 - 3-Phase Sinusoidal BLDC Motor Controller

General Description

The PT2501 is a three-phase, hall sensor sinusoidal brushless DC motor control chip.

The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase commutation.

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

Key Features

  • Hall sensor sinusoidal control for 3-phase BLDC.
  • Current limit function.
  • Over temperature protection from external NTC.
  • Motor lock protection.
  • Reverse function.
  • PWM or DC input for speed control.
  • FG output for rotation speed.
  • Pre-driver for 12V to 24V high side PMOS and low side NMOS.
  • Support Hall element and Hall sensor.
  • I2C interface for parameter setting and write to interal OTP.

Reference PT2501 3-Phase Sinusoidal BLDC Motor Controller DESCRIPTION The PT2501 is a three-phase, hall sensor sinusoidal brushless DC motor control chip. The three-phase control is based on sine wave driving scheme and it is designed to reduce electrical audible noise in motor phase commutation. On-chip +5V LDO provide voltage for logic and analog circuits operation. Combined with an external high voltage gate driver and six n-channel MOSFETs, PT2501 can operate with high voltage motor to 400V. For 12V to 24V operation, the built-in 60mA gate driving can connect to external high side PMOS and low side NMOS easily. The PT2501 offers external and internal OTP parameters setting to optimize with different motors and applications. The package of PT2501 is SSOP28.
