The MAX17823B is a data acquisition system for the management of high-voltage battery modules. The system features 12-bit SAR ADC that can measure 12cell voltages and two temperatures in 161μs. There are 12internal switches for cell balancing and extensive built-indiagnostics. Up to 32 devices can be daisy-chained togetherto manage 384 cells and monitor 64 temperatures. Cell voltages (0 to 5V) are measured differentially overa 65V common-mode range. Cell measurements have atypical accuracy of 2mV (3.6V cell, +25°C). If oversamplingis enabled, up to 128 measurements per channelcan be averaged internally with 14-bit resolution. The systemcan shut itself down in the event of a thermal overloadby measuring its own die temperature.The system uses Maxim’s battery-management UARTprotocol for robust communications and when used inconjunction with the MAX17880 12-channel battery monitor,they are ideal for automotive battery-managementsystems that require a high safety integrity level.ApplicationsBattery PacksBattery SystemsElectric BikesElectric Vehicles and Hybrid Vehicle (HEV)High-Power Battery Backup SystemsHigh-Voltage, Multi-Cell Series-Stacked-Power ToolsSuperCap Backup Systems
