MLX91219LVA-AAS-504-RE

Current Sensors Overview

The MLX91219LVA-AAS-504-RE is a board-mount current sensor IC from Melexis, utilizing Hall effect technology with an analog output. It operates on a 5V supply (4.5V to 5.5V range) and features a sensitivity of 22.5mV/mT. The device offers a bandwidth of 400kHz and a response time of 2µs. It supports AEC-Q100 qualification and functions within a temperature range of -40°C to +150°C. Packaged in a SIP-4 format measuring 5.43mm x 3.46mm x 1.2mm, it includes programmable offset and sensitivity for end-of-line calibration.

Current Sensors Feature Summary

• Integrates dual over-current detection (OCD) functionality for robust fault monitoring.
• Supports end-of-line programming for offset, sensitivity, filtering, and internal OCD thresholds.
• Features high signal-to-noise ratio (SNR) to simplify module design.
• Provides flexible power supply options compatible with 3.3V and 5V systems.

Current Sensors Applications

• Motor control systems requiring fast switching response
• Inverter and converter applications
• Battery management system (BMS) redundant detection

Current Sensors Procurement Notes

Verify the specific suffix 'AAS' indicates the analog output variant and '504' denotes the 22.5mV/mT sensitivity configuration. Confirm that the SIP-4 package matches your PCB footprint requirements. Ensure compatibility with PTC-04 or DB-HALL05 programmers for necessary end-of-line calibration procedures before finalizing procurement.

Current Sensors Selection Notes

Select this component when high-speed response (400kHz) and precise analog measurement are critical. The dual OCD feature makes it suitable for safety-critical applications. Consider the SIP-4 package size constraints and the need for external magnetic core integration. Verify that the 5V supply voltage aligns with your system architecture and that programmability meets your production calibration capabilities.

Current Sensors Part Context

This part belongs to the MLX91219 series of traditional Hall effect current sensors. It is designed as a monolithic solution for measuring DC and AC currents. The series emphasizes high precision and speed, targeting automotive and industrial environments where reliability and thermal stability are paramount. It complements other variants offering different sensitivities and packaging options like SOIC-8.

Current Sensors Replacement Considerations

Direct substitutes include other MLX91219 variants with matching sensitivity and package, such as MLX91219LVA-AAA-502-BU, provided the sensitivity difference is acceptable. Cross-reference mechanical dimensions and pinout configurations carefully. Verify that alternative parts support the required 400kHz bandwidth and dual OCD functionality if these are critical design constraints.
