HAH3DR 900-S00/SP4

Current Sensors Overview

The LEM HAH3DR 900-S00/SP4 is an open-loop Hall effect current sensor designed for automotive traction inverters. It measures bidirectional AC and DC currents with a primary nominal current of 900 A. The device provides a proportional isolated output, where 0 A corresponds to 2.5 V, +IPN to 4.5 V, and -IPN to 0.5 V. Key electrical specifications include ±1% linearity, ±3% accuracy, and a response time of 6 µs. It operates on a 4.75V to 5.25V supply with a maximum current consumption of 60mA.

Current Sensors Procurement Notes

Verify the specific suffix (S00/SP4) against the manufacturer's official documentation to ensure correct mechanical mounting configuration and connector type. Confirm that the component meets ISO 26262 requirements for the intended safety-related application environment. Cross-reference the part number with the latest datasheet revision to validate electrical parameters such as linearity and accuracy before procurement.

Current Sensors Selection Notes

Select this sensor for high-power motor control applications requiring fast response times and high bandwidth. The S00 variant is specifically engineered for installation on thick busbars with cable connectors, distinguishing it from module-integrated versions. Ensure the system can accommodate the required 4.75V to 5.25V supply voltage and that the 60mA current draw fits within the available power budget.

Current Sensors Part Context

This component belongs to the HAH3DR series, a family of three-phase current sensors developed by LEM for xEV traction inverters. The series offers various current ratings and mechanical designs to support different integration strategies. The HAH3DR 900-S00/SP4 represents a specific configuration optimized for busbar mounting, providing high isolation and precision for demanding automotive power electronics environments.

Current Sensors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider other variants within the HAH3DR series, such as HAH3DR 900-S07/SP4, if a different mechanical form factor for inverter module integration is required instead of busbar mounting.
