## CSNV700 SERIES 

## **Flux Gate Current Sensors** 

## DESCRIPTION 

The CSNV700 Series are advanced flux gate current sensors that use Honeywell's patented technology to bring the best combination of performance and reliability. They are non-intrusive and electrically isolated from the monitored circuit. This ensures a simple and reliable structure without loss of power to the monitored circuit. The CSNV700 Series are rated for a primary current measurement range of ±700 A dc. They are calibrated and temperature compensated for improved accuracy using multi-point temperature characterization. The CSNV700 incorporates AEC-Q100 qualified integrated circuits to meet higher quality and reliability requirements. 

## DIAGNOSTIC FUNCTIONALITY/ CAN OUTPUT 

The CAN output of the CSNV700 Series provides fault detection and communication capability. Also, the digital CAN communication is resistant to electrical interference. Examples of sensor and host system faults are as follows: 

- Sensor fault 

- Supply voltage over range 

- Supply voltage under range 

- Current over range 

## CUSTOMIZATION 

The CSNV700 Series may be customized to meet application needs. Solutions may be tailored to exact specifications for improved time to market, lower total system costs and enhanced reliability. For technical assistance, we provide global engineering and service support for your needs. 

## DIFFERENTIATION 

- **Accuracy:** Multi-point temperature characterization and calibration for improved accuracy over temperature range. 

- **Magnetic immunity:** Flux gate configuration and optimized magnetic circuit allow for excellent performance in diverse magnetic environments. 

- **Flexible:** Customizable on-board firmware to meet specific application requirements. 

## VALUE TO CUSTOMERS 

- **Accurate:** Designed to enable precise battery state measurement for improved user experience. 

- **Ease of use:** Magnetic immunity allows for easy integration into different magnetic environments. 

- **Easy system integration:** CAN communication is transmitted using international road vehicle standard ISO 11898. CAN 2.0B is the default protocol, CAN 2.0A is available as a custom variant. 

## APPLICATIONS 

- Current measurement for battery management systems in electrified vehicles (EV, HEV, PHEV or BEV) 

- Current leakage detection and fault isolation in charging systems 

- Current measurement in energy storage systems 

- Fault detection in heavy industrial equipment 

## AEC-Q100 

## FEATURES
