The MAX17823H is a data acquisition system for the management of high-voltage battery modules. The system features a 12-bit SAR ADC that can measure 12 cell voltages and two temperatures in 161 µs. There are 12 internal switches for cell-balancing and extensive built-in diagnostics. Up to 32 devices can be daisy-chained together to manage 384 cells and monitor 64 temperatures.
Cell voltages (0V to 5V) are measured differentially over a 65V common-mode range. Cell measurements have a typical accuracy of 2mV (3.6V cell, 25°C). If oversampling is enabled, up to 128 measurements per channel can be averaged internally with 14-bit resolution. The system can shut itself down in the event of a thermal overload by measuring its own die temperature.
The system uses Maxim’s battery-management UART protocol for robust communications and, when used in conjunction with the MAX17880 12-channel battery monitor, is ideal for automotive battery-management systems that require a high safety-integrity level.
