Maxim Integrated Products Inc. has rolled out five high-integration products for factory automation and automotive markets that the company said significantly improve operating efficiencies and reduce costs. Maxim has also collaborated with two firms to come up with a reference design for a highly integrated telehealth fitness ("Fit") shirt that monitors vital signs and lowers the cost of medical diagnosis, added the company.

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 ADC, and flexible and configurable sensor interfaces that allow for the measurement of current, voltage, speed, vibration, position and temperature. The ADC enables a less than 0.5 per cent energy calculation error compared to the five per cent of a standard microprocessor solution, detailed Maxim.

The MAX31865 claims to be the industry's first fully integrated RTD-to-digital converter, a single-chip solution that is said to lower costs 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.

The MAX17823 is 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 maximises 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.

The MAX9273/MAX9272 (22 bits) and MAX9271/MAX9272 (16 bits) serial-data chipsets transmit over coax cables and lower costs for automotive camera systems by up to 50 per cent, boasted Maxim. The chipsets reduce power use, process signals faster and improve electromagnetic emissions compared to standard solutions using Ethernet cables. The camera chipsets operate at very high data rates (1.5Gb/s), which is critical for today's fast video and megapixel image transmissions. Using coax cables, the chipsets do not need to compress data and thus process images immediately—a crucial requirement for safety applications like sign recognition, collision avoidance and night vision.

Maxim "Fit" shirt enables medical professionals to perform frequent and less costly fitness monitoring that will lead to more effective preventive medical care, described the company. The highly integrated shirt measures 3-lead ECG, body temperature and motion. All diagnostic tools are packaged in the that integrates dry ECG sensor technology, complex signal processing technology, a temperature sensor, motion sensor, an ultra-low-power microcontroller and wireless electronics.
