LIN motor driver improves EV AC applications
As precise control of cabin airflow and temperature becomes more critical in vehicles to enhance passenger comfort as well as to support advanced thermal management systems, Melexis introduces the MLX81350 LIN motor driver for air conditioning…
Dual-range motion sensor simplifies IIoT system designs
STMicroelectronics debuts the tiny ISM6HG256X three-in-one motion sensor in a 2.5 × 3-mm package for data-hungry industrial IoT (IIoT) systems, while also supporting edge AI applications. The IMU sensor combines simultaneous low-g (±16 g)…
A current mirror reduces Early effect
It’s just a fact of life. A BJT wired in common emitter, even after compensating for the effects of device and temperature variations, still isn’t a perfect current source.

Designing a thermometer with a 3-digit 7-segment indicator
Transforming a simple 10-kΩ NTC thermistor into a precise digital thermometer is a great example of mixed-signal design in action. Using a mixed-signal IC—AnalogPAK SLG47011—this design measures temperatures from 0.1°C to 99.9°C with…
The shift from Industry 4.0 to 5.0
The future of the global industry will be defined by the integration of AI with robotics and IoT technologies. AI-enabled industrial automation will transform manufacturing and logistics across automotive, semiconductors, batteries, and beyond.…
Back EMF and electric motors: From fundamentals to real-world applications
Let us begin this session by revisiting a nostalgic motor control IC—the AN6651—designed for rotating speed control of compact DC motors used in tape recorders, record players, and similar devices.
The figure below shows the AN6651’s block…
A precision, voltage-compliant current source
A simple current source
It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on the right side of Figure…
Beyond the current smart grid management systems
Modernizing the electric grid involves more than upgrading control systems with sophisticated software—it requires embedding sensors and automated controls across the entire system. It’s not only the digital brains that manage the network…
A tutorial on instrumentation amplifier boundary plots—Part 1
In today’s information-driven society, there’s an ever-increasing preference to measure phenomena such as temperature, pressure, light, force, voltage and current. These measurements can be used in a plethora of products and systems, including…
Board-to-board connectors reduce EMI
Molex LLC develops a quad-row shield connector, claiming the industry’s first space-saving, four-row signal pin layout with a metal electromagnetic interference (EMI) shield. The quad-row board-to-board connector achieves up to a 25-dB reduction…
