Melexis Technologies NV DVK91220 - SOIC16

Overview

DVK91220-SOIC16 from Melexis is a development kit designed to evaluate the MLX91220 and MLX91221 isolated integrated current sensor ICs in SOIC-16 package, supporting factory-calibrated 50 A measurement, IEC/UL 62368-1 rated isolation up to 4.8 kV RMS, and AEC-Q100 qualification for automotive use.

For engineers reviewing the DVK91220-SOIC16 datasheet, pinout, applications, or equivalent options, this kit enables rapid functional validation of high-common-mode-field-rejection analog current sensing with screw-terminal primary-side connection and header-based secondary-side interface.

Technical Context

The DVK91220-SOIC16 supports evaluation of the MLX91220 (5 V supply) and MLX91221 (3.3 V supply) current sensors, both featuring galvanic isolation, differential sensing architecture, and high-speed analog output. It includes two PCB variants: one pre-mounted with MLX91220KDC-ABF-050, and one blank for custom IC integration.

Board dimensions are fixed at 47 × 40 mm across variants. Isolation rating is specifically 4.8 kV RMS per IEC/UL 62368-1 for the SOIC-16 version, and EMC performance is enhanced by dedicated ground layer and decoupling capacitors.

FAQ

What is the purpose of the DVK91220-SOIC16?

The DVK91220-SOIC16 is a ready-to-use development kit for evaluating the MLX91220 and MLX91221 isolated current sensors in SOIC-16 package. It includes a pre-mounted MLX91220KDC-ABF-050 board and a blank board for custom IC integration, enabling immediate functional testing of 50 A current measurement with 4.8 kV RMS isolation. DVK91220-SOIC16 supports both 5 V and 3.3 V sensor variants and features M3 screw terminals and pin headers for flexible interfacing.

Does the DVK91220-SOIC16 include a populated current sensor IC?

Yes, the DVK91220-SOIC16 includes one evaluation board pre-populated with the MLX91220KDC-ABF-050 IC - a SOIC-16 packaged, 50 A factory-calibrated variant of the MLX91220. It also includes a second blank board for users to mount their own MLX91220 or MLX91221 device, supporting custom voltage or sensitivity requirements. DVK91220-SOIC16 thus serves both out-of-box validation and flexible prototyping needs.

What isolation voltage does the DVK91220-SOIC16 support?

The DVK91220-SOIC16 supports 4.8 kV RMS galvanic isolation per IEC/UL 62368-1, specific to the SOIC-16 package configuration. This higher isolation rating compared to the SOIC-8 variant (2.4 kV RMS) enables safe evaluation in medium-voltage applications such as on-board chargers and traction inverters. DVK91220-SOIC16 achieves this via optimized creepage/clearance layout and reinforced insulation design on its 47 × 40 mm PCB.

Can the DVK91220-SOIC16 be used with the MLX91221 sensor?

Yes, the DVK91220-SOIC16 is fully compatible with the MLX91221, which operates at 3.3 V supply voltage versus the MLX91220's 5 V. The board provides appropriate power conditioning and signal routing for both devices. Users can either populate the blank board with MLX91221 or adapt the pre-mounted board's supply rail. DVK91220-SOIC16's dual-voltage support makes it a unified platform for evaluating both members of the MLX91220/21 family.

What mechanical interface options does the DVK91220-SOIC16 provide?

The DVK91220-SOIC16 provides M3 screw terminals on the primary side for secure, solderless connection of high-current busbars or cables, and a standard 0.1-inch pin header on the secondary side for analog output, supply, and ground access. Its 47 × 40 mm rigid PCB is optimized for high-current trace routing and thermal stability. DVK91220-SOIC16's mechanical design ensures repeatable test setups and compatibility with standard lab equipment and breadboarding workflows.
