More than Memory

I don’t know about you, but when I hear “Spansion,” I hear memory. But there’s more going on there these days than FLASH. I talked with them last November when they were exhibiting at the IDTechEx show, which is partly about energy harvesting.

In particular, they acquired Fujitsu Microelectronics a year or so prior to broaden their product line. What they got were microcontrollers, with lots of digital and analog connectivity, and analog – primarily power management ICs (PMICs).

With this, they’re gunning for the internet of things (IoT). Surprise! Bet you didn’t see that coming… But they think that batteries are slowing adoption of IoT technology due to their need for low voltages and currents.

So their contribution to this situation is a couple of PMICs for energy harvesting – one is buck (drops in the incoming voltage); the other is boost (although it can drop voltage too if both needed).

The MB39C811 is targeted at regulating the voltages generated by solar (dye-sensitized cell and amorphous silicon) and vibrations (through piezoelectric or electret harvesters). The MB39C831 targets all solar as well as thermal harvesting.

They’re targeting industrial applications with these, so they’re pretty full-featured. They’re also working on slimmed-down versions for wearables.

They also have a simulator they call EasyDesign for configuring the energy harvesting module. Based on the needs of the node being powered, it can help determine, for example, how big a solar array is needed, and what the follow-on circuits should look like.

Common Design Pitfalls When Designing With Hall 2D Sensors And How To Avoid Them

Sponsored by Texas Instruments

This article discusses three widespread application issues in industrial and automotive end equipment – rotary encoding, in-plane magnetic sensing, and safety-critical – that can be solved more efficiently using devices with new features and higher performance. We will discuss in which end products these applications can be found and also provide a comparison with our traditional digital Hall-effect sensors showing how the new releases complement our existing portfolio.

High-Performance Motor Control Solutions Through Integration

Sponsored by Mouser Electronics and Qorvo

Brushless motors have taken over the market for a huge number of applications these days. But, it’s easy to blow up your BOM cost with all the motor control and power management components required. In this episode of Chalk Talk, Amelia Dalton chats with Marc Sousa of Qorvo about the Power Application Controller (PAC) that can lower your BOM, trim down your component list, and give you several other benefits as well.
