MAX17852ACB/V+

ADCs/DACs - Special Purpose Overview

The MAX17852ACB/V+ is a high-voltage, ASIL D-compliant data-acquisition system designed for managing battery modules. It features 14 cell-voltage measurement channels with 65V common-mode range and integrated current-sense amplifier. The device supports redundant ADC and comparator acquisitions, completing all inputs in 263µs or 156µs via the ADC engine alone. It includes 14 internal balancing switches rated for >300mA, four configurable auxiliary inputs, and factory-trimmed oscillator. Operating from -40°C to +125°C, it utilizes UART, Dual-UART, or SPI interfaces and supports daisy-chaining up to 32 devices.
