Maxim Introduces Industry’s First Data Acquisition System

Maxim Integrated Products has launched MAX17852 14-channel, high-voltage, ASIL-D data-acquisition system. Designers of automotive battery management systems (BMS) can now deliver the highest level of safety for voltage, current, temperature and communication while also saving space and reducing solution cost with this system.

MaximDesigned for integration within electric vehicles, hybrid electric vehicles and other transportation systems, the IC is ideal for smart junction box, 48V and other automotive battery systems that can see voltages up to 400V and beyond.

“Enabling systems to achieve the highest level of safety (ASIL D) for a BMS system is a must for consumers to feel safe in their electrified vehicles,” said Tamer Kira, executive director for the Automotive Business Unit at Maxim Integrated. “The MAX17852 is the fastest and most accurate in voltage, current and temperature measurements and that is why it is the first battery data acquisition system in the industry to achieve the highest safety rating for all the major components of a BMS system.”

Through comprehensive diagnostics and a safety-driven architecture, Maxim Integrated designed and manufactured the MAX17852 to enable customers to design their systems to meet the highest ASIL-D standards for voltage, current, temperature and communication.

The small, cost-effective IC also offers the highest accuracy for delivering voltage, current and temperature data with tight time synchronization. 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.

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.

Key Advantages

  • Highest Safety: ASIL-D rating for voltage, current, temperature and communication enhances safety
  • Highest Accuracy: Measurement accuracy with best current sense amplifier gain error to allow accurate, time-aligned current measurements to potentially boost mileage
  • Smaller Size: High integration enables up to 16 percent smaller size than a discrete solution to save board space
  • Lower Cost: Integrated current sense amplifier provides up to 20 percent cost savings
  • Versatility: The first device that can be adapted to many applications with voltage, current and temperature sensing
