We just published the video of our webinar on power management solutions for IoT and industrial applications, and anyone can just watch it after filling up a form. The presentation started with Jacob Wischmann, Senior Application Engineer, who touched on 5 V, 24 V, and 48 V solutions. Even for engineers with years of experience under their belt, power management solutions can still represent a challenge. These are complex systems, and a mistake can lead to catastrophic results. It was thus crucial for Jacob to start with an overview of the building blocks that often make up a power stage. He introduced the STEF0 E-Fuse, the L7987/L, and the L7983, an upcoming 60 V for lighter loads (typically 300 mA) with excellent quiescent current (10 µA) as well as an adjustable ultra-low-voltage lockout and dynamic low consumption. ST will officially release the L7983 in a few months.
Webinar on Power Management, the Lesser-Known Features of the STPMIC1
The webinar on power management then moved onto Noor Aizad, Technical Marketing Engineer, who delved on the STPMIC1. Noor started by exposing a feature that many may not know. Regardless of the version, all STPMIC1 variants are reprogrammable for greater flexibility. For instance, a team using the STPMIC1A, with its default voltage I/O of 3.3 V, can reprogram the device for a battery-powered system to get a voltage I/O of 1.8 V. In this particular instance, engineers don’t have to purchase the STPMIC1B, which offers a VIO of 1.8 V by default, but can repurpose the STPMIC1As they already have in stock. The presentation provided other valuable information on the power management IC, such as its ranks power up and power down sequence, or that one can assign any of the LDOs and buck converters to any of the ranks for the ultimate customization.
Webinar on Power Management, the Underrated Importance of ESD Protections
Noor then concluded the presentation with ESD protection, which is crucial when using USB ports, network interfaces, or audio jacks, among many other connectors. Additionally, to make the subject matter more pragmatic, the presentation took an STM32MP1 evaluation board and looked at the various ESD protections it embarks. Not only did it help viewers understand the importance of each protection measure, but it also showed how we implement them, thus giving engineers a leg up on their designs. The video also included a little less than 20 minutes of questions and answers from the audience, thus bringing additional technical information about the various products presented.
