    OB6611

    Genenal Description

    OB6611isa low system costbrushless DC motor (BLDC) controller, including8051-compatible MCU processor,5V-LDOwith high precision voltage and 15mAoutputcurrent,three channels high sideP-channel MOSFET(P-MOSFET)gatedriver, three comparators used for sensorless control.

    OB6611is optimized for low cost, high-efficiency drive circuits in applications, andeasy to built BLDC control circuit with current loop and speed loop by using simple components.OB6611provides large flexibility in adapting the OB6611to a specific system requirement and simplify the system design.

    QFN28 (5mm*5mm) and TSSOP28 package is favorable for PCB miniaturization design.
