AD7284 Battery Monitoring System

Analog Devices AD7284 8-Channel, Li-Ion Battery Monitoring System includes all the functions required for the general-purpose monitoring of stacked Li-Ion batteries. The AD7284 features multiplexed cell voltage and auxiliary ADC measurement channels to support four to eight battery management cells. Designers can use the four auxiliary ADC input channels for temperature measurement or system diagnostics. With eight differential analog input channels, the AD7284 can accommodate large common-mode signals across the full VDD range. AD7284's design also includes two on-chip 2.5V voltage references. One voltage reference is for the primary measurement path, and the other is designated for the secondary measurement path. The integrated secondary measurement path validates the data on the primary 14-bit ADC. Other diagnostic features include the detection of open inputs, communication, and power-supply related faults. The AD7284 offers a ±3mV maximum cell voltage accuracy, ±16mV typical battery stack voltage (TUE) accuracy, and very low measurement latency across 96 cells. Qualified for automotive applications, the AD7284 Battery Monitoring System is ideal for Li-Ion battery monitoring, electric & hybrid electric vehicles, and stationary power applications.Learn More
