The battery monitor IC with integrated current sense amplifier offers up to 16 percent space and 20 percent cost savings
The MAX17852 is a small, cost-effective IC that offers high accuracy for delivering voltage, current and temperature data with tight time synchronisation. It allows a typical cell voltage measurement of ±0.45mV at room temperature and a maximum of ±2mV error in a temperature range of 5 degrees to 40 degrees Celsius, enabling car OEMs to get the most mileage range out of their batteries.
With a current sense amplifier capability of +/-300mV and a gain setting up to 256 times and 0.3 per cent current sense gain error, the MAX17852 provides a fast, accurate data for calculating power management, state of health and state of charge. The 14-channel battery data acquisition system integrates a current sense amplifier so that current information is acquired at the same time as cell voltage and temperature. The MAX17852 allows both Hall effect sensor and shunt resistors to be used as sensing components.
Other key features
- Small size: High integration enables up to 16 per cent smaller size than a discrete solution to save board space.
- Low cost: Integrated current sense amplifier provides up to 20 per cent cost savings
The MAX17852 and the MAX17852EVKIT# evaluation kit is available from Maxim Integrated or authorised distributors.
