Mingjiada original supply A5932KLPTR three-phase non-inductive fan controller: wide-voltage drive + silent design, the preferred solution for intelligent cooling system

1. Product Core Characteristics

A5932KLPTR is a three-phase sensorless motor controller from Allegro MicroSystems, designed for high-precision fan speed regulation and industrial motor control, with the following technical advantages:

Wide voltage input range

Supports 5V-50V DC power supply, adapts to 12V/24V/48V systems, and is compatible with automotive, industrial and consumer electronics power supply environments 6.

High-efficiency sine wave drive

Adopting sensorless FOC (Field Orientation Control) algorithm, the harmonic distortion rate of output current is <5%, which significantly reduces motor noise (≤25dB) and vibration 68.

Intelligent speed control interface

Supports PWM/analog voltage dual-mode speed control, frequency range 100Hz-20kHz, duty cycle resolution up to 0.1%, stepless linear control from 0-100% 26.

Multiple protection mechanisms

Integrated over-current/over-temperature/under-voltage lockout (UVLO) protection, fault response time <2μs, to ensure safe system operation 15.

Compact Industrial Package

24-TSSOP-EP (with thermal pads) package, the size of only 4.4mm × 7.8mm, to meet the needs of high-density PCB layout 18.
