Overview

The MLX91208LDC-CAV-001-RE is a high-speed, programmable Hall-effect current sensor designed for non-contact measurement. Utilizing Melexis' proprietary Integrated Magnetic Concentrator (IMC-Hall) technology, it provides a linear analog output proportional to the magnetic field parallel to the chip surface, enabling high-bandwidth current sensing without the need for bulky ferromagnetic cores.

Why Choose This Part

The sensor features a high bandwidth of 150 kHz, making it suitable for fast switching power electronics. Being AEC-Q100 qualified, it offers automotive-grade reliability and a programmable transfer characteristic that allows for ratiometric analog output calibration to specific application requirements.

Applications

EV Inverter Phase Current Sensing
Monitoring high-frequency phase currents in electric vehicle traction inverters for motor control.
DC/DC Converters
Providing feedback loops for power conversion stages in high-voltage automotive and industrial power supplies.
Battery Management Systems (BMS)
Measuring charge and discharge currents in high-current battery packs for SOC and SOH estimation.
Smart Fuse Boxes
Electronic circuit breaking and overcurrent protection in automotive power distribution units.

Getting Started

To evaluate this sensor, use the Melexis PTC-04 programmer to configure the internal EEPROM for sensitivity and offset calibration. Design the PCB with a current-carrying trace or busbar positioned according to the IMC-Hall sensitivity axis to ensure optimal magnetic field coupling.
