Add a Secure Element to Build Edge-to-Cloud Security into an IoT Design

Cybersecurity remains a universal problem in the design and deployment of any system connected to the public Internet. In the Internet of Things (IoT), security problems are particularly acute as users begin to question the ability of connected devices to securely support applications in smart homes, smart factories, or smart cities. Yet, in facing tighter delivery schedules, IoT device developers …


Use High-Current IGBT Drivers with Built-In Protection for Reliable Industrial Motor Control

Use High-Current IGBT Drivers with Built-In Protection for Reliable Industrial Motor Control

In an ongoing effort to reduce costs and lower energy consumption in industrial control applications, designers are turning to high-frequency, high-current brushless direct current (BLDC) motors. These increasingly rely upon faster insulated-gate bipolar transistors (IGBTs) instead of metal-oxide-semiconductor field-effect transistors (MOSFETs) for faster switching in order to boost power density. However, to operate efficiently and safely, designers need to include …


How to Design Low-Power Always-On Wearables: Part 1 – Optimize the Microcontroller

How to Design Low-Power Always-On Wearables: Part 1 – Optimize the Microcontroller

Editor’s note: This is Part 1 of a three-part series on designing battery-powered always-on wearable electronics, focusing on three areas in which to optimize for power. Here, Part 1 describes how to configure the microcontroller to extend battery life and reduce recharges. Part 2 looks at how to properly maintain the battery to extend time between recharges. Part 3 examines …
