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 that 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.
