MLX91219LVA-AAA-300-CR

Current Sensors Overview

The MLX91219LVA-AAA-300-CR is a board-mount current sensor IC from the Melexis MLX91219 series, designed for high-speed applications. It features an analog output and operates on a 3.3 V supply voltage with a maximum rating of 3.465 V and minimum of 3.135 V. The device has a rated current of 50 mA, a response time of 2 µs, and a frequency range of 0 Hz to 400 kHz. It is housed in a SIP-4 package measuring 5.43 mm in length, 3.46 mm in width, and 1.2 mm in height. The component is qualified under AEC-Q100 standards and functions within a temperature range of -40 °C to +150 °C.

Current Sensors Feature Summary

• Features a high-speed analog output suitable for rapid switching environments
• Includes programmable parameters such as offset, sensitivity, filtering, and internal overcurrent thresholds
• Utilizes conventional Hall technology with factory calibration across the operating temperature range

Current Sensors Applications

• Motor control systems requiring fast response times
• Inverter and converter applications with high-frequency switching
• Battery management system redundancy detection

Current Sensors Procurement Notes

Verify the specific suffix 'CR' against official Melexis documentation to confirm availability and exact specifications, as standard listings may reference 'SP' or 'BU' variants. Ensure compatibility with PTC-04 programming tools if field adjustment is required. Confirm that the SIP-4 package dimensions fit the target PCB layout constraints. Check regional distribution status as some variants may have restricted availability in certain markets.

Current Sensors Selection Notes

Select this variant when a 3.3 V supply voltage is mandatory for the system architecture. The 400 kHz bandwidth supports high-frequency motor control and inverter applications where signal integrity is critical. The analog output type requires external processing but offers flexibility for custom threshold settings. Consider the SIP-4 package size for designs needing integration into narrow magnetic core air gaps to maximize signal-to-noise ratio.

Current Sensors Part Context

This component belongs to the MLX91219 family of traditional Hall effect current sensors. The series is characterized by its ability to measure currents ranging from 200 A to 2000 A or higher when used with appropriate magnetic cores. The LVA suffix typically denotes the SIP-4 thin package format, which facilitates installation in tight spaces compared to larger SOIC-8 options.
