ICs For Industrial And Automotive Applications

Maxim has introduced five high-integration products for the factory automation and automotive markets to improve operating efficiencies and reduce costs.

For factory automation and process control, there are the MAX31865 RTD-to-digital converter and the MAX78638, a turnkey solution for 3-phase motor energy measurement and diagnostics.

The 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.
The MAX31865 is a single-chip solution for digitising a platinum RTD (such as a Pt100 or Pt1000) resistance.

Maxim also introduced three new products for the automotive market:
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 chip is designed to maximise 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%. The chipsets claim to reduce power use, process signals faster and improve electromagnetic emissions compared to standard solutions using Ethernet cables.

Maxim’s new camera chipsets operate at very high data rates (1,5 Gbps), 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.
