Connect up to 32 devices in a daisy chain
Manages 448 cells, monitors 128 temperatures
Meets ASIL-D and FMEA safety requirements


Mouser Electronics announced on the 31st that it is supplying Maxim Integrated's 'MAX17852' 14-channel high-voltage ASIL-D rated data acquisition (DAQ) system.

Electric vehicle (EV) battery management system (BMS) designers can implement voltage, current, temperature, and communication safety through the MAX17852, and also reduce space and cost.

The MAX17852 is a solution for managing high-voltage/low-voltage battery modules in EVs, hybrid EVs, and other transportation systems, and is suitable for smart junction boxes, 48V, and other automotive battery systems operating at voltages of 400V, 800V or higher.

With a fully redundant measurement engine, 14 cell voltages, 1 current, 4 temperature combinations, or system voltage can be measured within 263 μs. With an analog-to-digital converter (ADC) measurement engine, all inputs can also be processed within 156 μs. Up to 32 devices can be connected in a daisy-chain manner to manage 448 cells and monitor 128 temperatures.

It is equipped with Maxim's battery management UART and SPI protocols and supports an I²C master interface for external device control. The embedded communication and hardware warning interfaces, which partially support internal diagnostics and rapid warning communication functions, meet ASIL-D and FMEA requirements.

Meanwhile, Mouser also supplies the 'MAX17852' evaluation kit, which combines the 'MAX17841B' evaluation kit with a host PC, for designers who want to utilize the MAX17852.
