***ical: Battery Monitoring Li-Ion 1mA 5V Automotive 64-Pin LQFP EP T/R

***ark: 8 Ch Li-Ion Monitor Iso26262/Auto

***log Devices: The AD7284 contains all the functions required for the general-purpose monitoring of stacked Li-Ion batteries, as used in hybrid electric vehicles and battery backup applications. The AD7284 has multiplexed cell voltage and auxiliary, analog-to-digital converter (ADC) measurement channels supporting four to eight cells of battery management. The device provides a maximum total unadjusted error, TUE, (cell voltage accuracy) of ±3 mV that includes all the internal errors from input to output. The primary ADC resolution is 14 bits. The AD7284 also includes an integrated secondary measurement path that validates the data on the primary ADC. Other diagnostic features include the detection of open inputs, communication, and power supply related faults. The AD7284 cell balancing interface outputs control the external field effect transistors (FETs) to allow discharging of individual cells. There are two on-chip 2.5 V voltage references: one reference for the primary measurement path, and one for the secondary measurement path. The AD7284 operates from one VDD supply, ranging from 10 V to 40 V. The device provides eight differential analog input channels to accommodate large common-mode signals across the full VDD range. Each channel allows an input signal range, VPINx − VPIN(x − 1) and VSINx – VSIN(x − 1), of 0 V to 5 V, where x = 0 to 8. The input pins assume a series stack of eight cells. The AD7284 includes four auxiliary ADC input channels that can be used for temperature measurement or system diagnostics. The AD7284 has a differential daisy-chain interface that allows multiple devices to be stacked without the need for individual device isolation. By design, this interface allows both device to device communication within the same module and communication between devices on different modules. Applications Li-Ion battery monitoring Electric and hybrid electric vehicles Stationary power applications

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
