Product details
Overview
MLX90412GLW-BZZ-042-RE from Melexis is a single-coil brushless DC fan and pump driver IC with integrated high-sensitivity Hall-effect sensor, 2.2 A motor current limit, closed-loop speed control (±1.5% accuracy), adaptive low-noise commutation, and I²C programmability. It operates from 3.5 V to 32 V (robust to 40 V) and supports up to 35 W loads in smart cleaner robots, toilet pumps, and condenser dryer drain pumps.
For engineers reviewing the MLX90412GLW-BZZ-042-RE datasheet, pinout, applications, or equivalent options, key selection considerations include closed-loop speed accuracy, programmable locked rotor protection, I²C configuration capability, wettable-flank DFN10 package compatibility, and UL/VDE/CE readiness for consumer appliance designs.
Technical Context
The MLX90412GLW-BZZ-042-RE implements sensor-based commutation using an on-chip Hall-effect sensor and supports both open-loop and closed-loop speed control modes. Its adaptive commutation algorithm dynamically adjusts timing across the full speed range to maximize efficiency and minimize acoustic noise.
It integrates programmable protections including locked rotor detection (LRP), overvoltage protection (OVP), thermal shutdown (TSD), short-circuit (OCP), and current limiting (CL), with diagnostics output via FG/RD open-drain pin. I²C interface enables end-of-line programming and fast prototyping without external microcontroller dependency.
