Current Sensors datasheet and documents for MLX91209LVA-CAA-002-BU
Current Sensors Overview
The MLX91209LVA-CAA-002-BU is a single-channel, bidirectional Hall effect current sensor manufactured by Melexis Technologies NV. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 14mA. The device features a sensitivity of 7.3mV/mT and supports frequencies from DC to 200kHz or 250kHz depending on the source. It exhibits a linearity of ±0.4% and a response time of approximately 2µs to 3µs. The sensor is housed in a 4-SIP through-hole package and is rated for an operating temperature range of -40°C to 125°C or 150°C.
Current Sensors Feature Summary
- Fully programmable transfer characteristics including offset, sensitivity, and response time via customer programming.
- Provides high-speed analog output signals proportional to external magnetic flux density with fast response times.
- Includes integrated overvoltage protection and reverse voltage protection with diagnostic capabilities.
Current Sensors Applications
- Current measurement in hybrid electric vehicles (HEV) and electric vehicles (EV).
- Inverter applications requiring extremely fast response times.
- Solar panel monitoring systems.
Current Sensors Procurement Notes
Verify the specific sensitivity value against the official datasheet, as sources indicate variations such as 7.3mV/mT versus the standard 50mV/mT default. Confirm the exact operating temperature range (-40°C to 125°C or 150°C) and frequency bandwidth (200kHz vs 250kHz) required for your design. Ensure the 4-SIP through-hole package aligns with your PCB layout constraints before finalizing procurement.
Current Sensors Selection Notes
Select this component when a fully programmable, high-speed Hall effect current sensor is required for automotive or industrial applications. It is suitable for designs needing precise calibration of sensitivity and offset. Consider the 4-SIP package size and through-hole mounting requirements. Verify compatibility with the intended magnetic core configuration, typically a soft iron ring core, for optimal performance.
Current Sensors Part Context
This part belongs to the MLX91209 series of programmable Hall effect current sensors. The series is designed for high-precision current sensing with enhanced thermal stability. The MLX91209 family offers flexibility through customer-programmable parameters, making it adaptable to various application needs while maintaining automotive-grade reliability and small form factor.
Current Sensors Replacement Considerations
Other variants within the MLX91209 series, such as MLX91209LVA-CAA-005-BU or MLX91209LVA-CAK-001-RE, offer different sensitivities (e.g., 8.78mV/mT or 15mV/mT) but share similar functional characteristics. Ensure the replacement part's sensitivity and packaging match the original design requirements.
