Overview

The A4963GLPTR-T is a three-phase, sensorless BLDC motor controller designed to drive external N-channel power MOSFETs. It operates over a wide 4.2V to 50V range and utilizes a proprietary sensorless startup and commutation algorithm, eliminating the need for Hall-effect sensors in the motor assembly.

Why Choose This Part

The device features a flexible SPI-compatible interface for programmable motor parameters and advanced diagnostics. It provides robust protection with integrated current limiting, short-circuit detection, and a wide operating temperature range from -25C up to 150C.

Applications

Industrial Fans and Blowers
Ideal for high-reliability air moving applications where sensor wiring is impractical due to environmental conditions.
Automotive Pumps
Used in coolant and oil pumps requiring efficient, high-voltage operation up to 50V with a wide temperature range.
High-Speed Centrifuges
Suitable for laboratory equipment needing precise control over brushless motors without the complexity of physical sensors.
