The HAH3DR S07/SP42 three-phase sensor has been designed to fit these 800V power modules. Thanks to its complete temperature calibration and stability throughout the device's lifespan, it accelerates time to market with minimal R&D effort. This makes it ideal for companies developing platforms for small vehicles, trucks, and buses with limited R&D resources.
Wide Current Range:
The new current sensor offers a wide selection of current measurement ranges from 700A to 1200A. Compared to existing models in the HAH3DR family, the package insulation characteristics have been improved to meet the challenge of 800V power modules. In addition to this new model, LEM also offers a wide variety of packages and current measurement ranges.
The HAH3DR S07/SP42 features a unique, enlarged opening that can accommodate busbars up to 1.5 mm thick, making it compatible with the latest generation of power modules. It is also compatible with power modules from other suppliers, such as the Acepak Drive from ST Microelectronics, the SSDC from ON Semi, and others like Starpower and CRRC.
As it is an improvement on an existing and proven product family, the HAH3DR S07/SP42 is compatible with the first generation HAH3DR S07/SP4 for 400V inverters, therefore no changes are necessary to use the new device.
The HAH3DR S07/SP42 is a product with the quality required for safety applications compliant with ISO 26262 under certain conditions, for which LEM can provide the necessary safety so that customers can even obtain ASIL D certification on the inverter.
Note on nomenclature:
• The LEM HAH3DR S07/SP42 is a three-phase Hall sensor for drive applications (DR = drive)
• S07 designates the subfamily specially developed for power modules such as the Hybridpack Drive
• SP42 designates the specific product within the S07 subfamily that is compatible with 800V power modules with long busbars
