Maxim Expands Power Management Offering for Industrial and Automotive Uses
Maxim Integrated Products, Inc. has added four high-integration products for the factory automation and automotive markets that improve operating efficiencies and reduce costs. These devices include a 3-phase motor energy management device, a temperature measurement chip and two battery management devices for automotive applications.
The MAX78638 is a turnkey solution for 3-phase motor energy measurement and diagnostics. Unlike previous bulky and expensive solutions that required moving the equipment from motor to motor, the fully integrated MAX78638 contains a microcontroller, compute engine, an analog-to-digital converter (ADC), and flexible and configurable sensor interfaces that allow for the measurement of current, voltage, speed, vibration, position, and temperature. The high-accuracy ADC enables a less than 0.5% energy calculation error compared to the 5% of a standard microprocessor solution.
The MAX31865 is the industry's first fully integrated RTD-to-digital converter, a single-chip solution that lowers costs by up to 50% and solves the common industrial design problem of digitizing a platinum RTD (such as a Pt100 or Pt1000) resistance. It offers simple and accurate measurement of temperature, making it ideal for industrial measurement and process control applications.
For the automotive market, Maxim added the MAX17823, a fourth-generation high-voltage battery sensor for mission-critical automotive and industrial lithium-ion battery and fuel cell applications. Offering a full suite of proprietary integrated ISO-26262 diagnostic features, the MAX17823 maximizes electric and hybrid electric vehicle driving range, while ensuring battery and fuel cell safety and reliability. Maxim also offers the MAX17830, a second-generation, high-voltage battery-management solution.
