- | [[http:// | + | [[adi>CN0235|CN0235]] is a Fully Isolated Lithium Ion Battery Monitoring System. Lithium ion (Li-Ion) battery stacks contain a large number of individual cells that must be monitored correctly in order to enhance the battery efficiency, prolong the battery life, and ensure safety. |
\\ | \\ | ||
\\ | \\ | ||
- | The 6-channel [[http:// | + | The 6-channel [[adi>ad7280A|AD7280A]] devices act as the primary monitor providing accurate voltage measurement data to the System Demonstration Platform (SDP-B) evaluation board, and the 6-channel [[adi>AD8280|AD8280]] devices act as the secondary monitor and protection system. Both devices can operate from a single wide supply range of 8V to 30 V and operate over the industrial temperature range of −40°C to +105°C |
\\ | \\ | ||
\\ | \\ | ||
- | The [[http:// | + | The [[adi>ad7280A|AD7280A]]contains an internal ±3 ppm reference that allows a cell voltage measurement accuracy of ±1.6 mV. The ADC resolution is 12 bits and allows conversion of up to 48 cells within 7 μs. It also has cell balancing interface outputs designed to control external FET transistors to allow discharging of individual cells and forcing all the cells in the stack to have identical voltages. |
\\ | \\ | ||
\\ | \\ | ||
- | The [[http:// | + | The [[adi>AD8280|AD8280]] functions independently of the primary monitor and provides alarm functions indicating out of tolerance conditions. It contains its own reference and LDO, both of which are powered completely from the battery cell stack. The reference, in conjunction with external resistor dividers, is used to establish trip points for the over/ |
