The A4960 is a three-phase, sensorless brushless DC motor controller designed to drive external N-channel MOSFETs using block commutation based on back-EMF detection. It operates from a 7 to 50 V supply voltage and is compatible with 3.3 V and 5 V logic levels. The device is packaged in a 32-pin LQFP with an exposed thermal pad for improved heat dissipation and is rated for an ambient operating temperature range of -20 to 85 °C with a maximum junction temperature of 150 °C. Integrated diagnostics provide fault indication for undervoltage, overtemperature, and power bridge conditions. The part includes a charge pump for low-voltage operation, adjustable dead time for cross-conduction protection, and automatic bootstrap capacitor management. It supports PWM current limiting and serial diagnostics output.
