Overview

The A4960KJPTR-T is a high-performance 3-phase sensorless brushless DC (BLDC) motor controller designed for use with external N-channel power MOSFETs. It operates from a load voltage of 7V to 50V and includes an integrated SPI interface for flexible configuration of motor parameters and diagnostic reporting.

Why Choose This Part

The controller features a programmable SPI interface that allows engineers to adjust dead time, current limits, and sensorless start-up profiles without hardware changes. It provides robust protection with integrated cross-conduction prevention, charge pump for low-voltage operation, and extensive diagnostic outputs.

Applications

Automotive Cooling Fans
Ideal for engine cooling and HVAC blowers due to its wide 150 degree Celsius operating temperature and automotive-grade durability.
Industrial Pumps
Utilizes sensorless commutation to drive 3-phase pumps without the need for Hall-effect sensors, reducing cabling and system complexity.
Battery Powered Tools
Supports low-power sleep modes with 10uA current consumption to extend battery life in high-torque cordless applications.
