PTC PT2501
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. For 12V to 24V operation, the built-in 60mA gate driving can connect to external high side PMOS and low side NMOS easily.| Part No. | PT2501 |

DESCRIPTION
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. The PT2501 offers external and internal OTP parameters setting to optimize with different motors and applications. The package of PT2501 is SSOP28.FEATURES
