Additional Details

The MAX17852 is a flexible data-acquisition system for the management of high-voltage and low-voltage battery modules. The system can measure 14 cell voltages, one current measurement, and a combination of four temperatures or system voltages with fully redundant measurement engines in 263µs, or perform all inputs solely with the ADC measurement engine in 156µs. There are 14 internal switches rated for > 300mA for cell-balancing, each supporting extensive built-in diagnostics. Up to 32 devices can be daisy-chained to manage 448 cells and monitor 128 temperatures.

Cell and bus-bar voltages ranging from -2.5V to +5V are measured differentially over a 65V common-mode range, with a typical accuracy of 1mV (3.6V cell, +25°C). If oversampling is enabled, up to 128 measurements per channel can be averaged internally with 14-bit resolution and combined with digital post-processing IIR filtering for increased noise immunity. The system can shut itself down in the event of a thermal overload by measuring its own die temperature.

For robust communications, the system uses Analog Devices' battery- management UART or SPI protocol for robust communications and supports an I²C master interface for external device control, and is optimized to support a reduced feature set of internal diagnostics and rapid-alert communication through both embedded communication and hardware-alert interfaces to support ASIL D and FMEA requirements.

Applications

48V system
Battery Backup Systems (UPS)
Battery Powered Tools
Electric Bikes
Electric Vehicles (EV)

Product Detail

The MAX17852 evaluation kit (EV kit) is used to demonstrate the features and capabilities of the MAX17852 14-channel high-voltage smart sensor data-acquisition interface IC. The EV kit is coupled with a MAX17841B EV kit to establish communication to a host PC. With communication established, control of the MAX17852 EV kit is executed through the EV kit graphical user interface (GUI) on the host PC. The GUI is Windows XP^®, Windows Vista^® Windows^® 7, and Windows 10 compatible and is available through your local Maxim Integrated sales office. Note: References to the MAX17841 in this data sheet pertain equally to the MAX17841B as well.

The MAX17852 EV kit design provides a convenient platform for evaluating the features and functions of the IC, in addition to the IC’s electrical parameters. The EV kit with vertical communication connectors (P2, P3, P5, and P6) and snap and lock battery pack connector enable the user to quickly build and evaluate a system with up to 32 daisy-chain devices.
