Integrated BLDC Motor Drivers


PT2515

PT2515 is a three-phase sine wave current BLDC motor driver IC with integrated control and driver, which can operate without Hall sensor or feedback from a single Hall IC. This chip has multiple protection functions, including over-current protection, over-temperature protection, locked protection and lack-of-phase protection. PT2515 supports VSP, PWM, Clock input methods to control the effective output voltage or speed of the motor. The motor parameters can be adjusted by external the capacitance or resistance, without software or program recording. PT2515 uses HTSSOP20/28 or QFN24 (4x4mm) small package, with few peripheral components, can achieve compact PCB layout. The typical operating voltage of PT2515 is 24V, and it can provide a maximum driving current of about 1A, which is suitable for use in 10W~24W motor applications.
