Maxim Integrated Announces Industry's First ASIL-D Compliant Data Acquisition System

     Maxim Integrated Products, Inc. introduces the MAX17852 14-channel, high-voltage, ASIL-D compliant data-acquisition system that helps automotive power management system (BMS) developers provide the highest level of safety for voltage, current, temperature measurement, and data communication, while enabling large-scale Save space and reduce program costs. Designed for system integration in electric vehicles, hybrid electric vehicles and other transportation vehicles, this IC is ideal for smart junction boxes, 48V and other automotive battery systems capable of withstanding 400V and beyond.

     OEMs and EV manufacturers require battery systems to meet the highest safety levels set by the ISO26262 standard. With comprehensive diagnostic capabilities and a safety-driven architecture, the MAX17852 designed and manufactured by Maxim Integrated helps customers meet the highest ASIL-D safety system requirements for voltage, current, temperature measurement, and data communications. Small, high-efficiency IC designs provide the highest measurement accuracy, using rigorous time synchronization techniques to provide voltage, current, and temperature data.

     The device can measure battery voltage changes of ±0.45mV (typ) at room temperature; the maximum measurement error is ±2mV over the 5°C to 40°C temperature range, helping automakers achieve the maximum range their batteries can support . The device features a +/-300mV current-sense amplifier with a maximum gain setting of 256 times and a current-sense gain error of 0.3%; these features ensure the MAX17852 provides the fastest, highest-accuracy data acquisition for computing power management, battery health, and state-of-charge. This 14-channel battery data acquisition system integrates the current detection amplifier, so that the current, voltage and temperature data can be collected simultaneously. The MAX17852 can use Hall sensors or current-sense resistors as sense elements.
