The MAX17823 is Maxim's fourth-generation, high-voltage battery-management solution. With higher accuracy, safety-enabling features, and an automotive-hardened SMBus ladder,the MAX17823 has been put through rigorous testing to ensure operation under the most hostile of EMC/EMI environments. The robust SMBus ladder daisy chain supports cable lengths of up to 2m and passes tough industry compliance testing. Cell-reversal capability and 96-cell hot-plug performance make pack assembly easy for high-cell-count systems.A host of ASIL D-enabling features makes safety assessment of pack operation simple and straightforward for any host microcontroller. |
