1 pcs : MAX17823BGCB/V+ - Battery Management 12-Channel, High-Voltage Sensor, Smart Data-Acquisition Interface

MAX17823B High Voltage Data Acquisition System Analog Devices Inc. MAX17823B High Voltage Data Acquisition System is for the management of high-voltage battery modules. The system features a 12-bit SAR ADC measuring 12x cell voltages and two temperatures in 161μs. There are 12x internal switches for cell balancing and extensive built-in diagnostics. Up to 32x devices can be daisy-chained together to manage 384x cells and monitor 64x temperatures. Cell voltages of (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 128x measurements per channel can be averaged internally with 14-bit resolution. The system can shut itself down during a thermal overload by measuring its die temperature. The system uses Maxim’s battery-management UART protocol for robust communication. When used with the MAX17880 12-channel battery monitor, it is ideal for automotive battery-management systems requiring a high safety integrity level.
