    A4963 Sensorless BLDC Controller
    FEATURES AND BENEFITS Three phase sensorless BLDC motor control FET driver Logic level P-N gate drive (P high-side, N low-side) 4.2 V to 50 V supply range Simple block commutation for maximum torque Sensorless (bemf sensing) start-up and commutation Programmable operating modes: Integrated Speed Control PWM Duty Cycle Control Current mode control Cross-conduction prevention Wide speed range capability Peak current limiting Single low frequency PWM control input Single Open Drain Fault output SPI compatible interface providing: Configuration and control Programmable dead time Programmable phase advance Detailed diagnostic reporting Fans DESCRIPTION The A4963 is a three-phase, sensorless, brushless DC (BLDC) motor controller for use with external complementary P-channel and N-channel power MOSFETs. The A4963 can be used as a stand-alone controller communicating directly with an electronic control unit (ECU) or it can be used in a close coupled system with a local microcontroller (MCU). The motor is driven using block commutation (trapezoidal drive) where phase commutation is determined, without the need for independent position sensors, by monitoring the motor backEMF (bemf). The sensorless start-up scheme allows the A4963 to operate over a wide range of motor and load combinations. Dedicated circuits allow the A4963 to operate over a wide range of motor speeds, from less than 100 rpm to in excess of 30,000 rpm, depending on the supply voltage and motor capability. Several operational modes are available including duty-cycle (voltage) control, current (torque limit) control and closed loop speed control. Operating mode and control parameters can be altered through an SPI compatible serial interface. Motor operation is controlled by a programmable PWM input that can be used to define the motor operating state and provide the proportional input for the selected operating mode. Integrated diagnostics provide indication of under voltage, over temperature and power bridge faults and can protect the power switches under most short circuit conditions. Faults are indicated by a single open drain output than can be used to pull the PWM input low. The A4963 is provided in a small, thermally enhanced 20-pin TSSOP with exposed thermal pad.
