A Paper Battery… Not

Today’s note comes from the Department of Not What It Sounds Like. It’s about a company called Paper Battery, which doesn’t make batteries, and, what it does make isn’t made out of paper. The burdens of old names that stick…

What they do make is a supercapacitor. We’ve talked about supercaps before; there’s nothing revolutionary in concept. The story with PBC (much less confusing company name as an acronym… but don’t confuse it with PCB) is about their form factor: thin (0.3 mm) and flat. They can be, for instance, added as a “layer” over a battery to provide a combined battery/supercap “bundle” that has much more stable voltage.

The idea here is that such a flat component can be spread out in ways that use less space than explicit components that need their own plot of PCB. But the spatial efficiencies come with specific extra benefits, both electrical and thermal. As a layer or “wrap,” these supercaps can provide electromagnetic shielding; they can also act as head spreaders, helping wick away heat from hot spots that they might cover or underlie.

In the future, you could see multiple caps and voltages, paving the way for better DC/DC converters.

They say they have the technology sorted, but they’re optimizing for higher-volume manufacturing. In a few months they’ll make the decision to use either a contract manufacturer or to build a fab. If they roll their own, they say that it would be 12-16 months from now when they went live; they could get a contract guy going 3-4 months faster.

How to Harness the Massive Amounts of Design Data Generated with Every Project

Sponsored by Cadence Design Systems

Long gone are the days where engineers imported text-based reports into spreadsheets and sorted the columns to extract useful information. Introducing the Cadence Joint Enterprise Data and AI (JedAI) platform created from the ground up for EDA data such as waveforms, workflows, RTL netlists, and more. Using Cadence JedAI, engineering teams can visualize the data and trends and implement practical design strategies across the entire SoC design for improved productivity and quality of results.

Gate Driving Your Problems Away

Sponsored by Mouser Electronics and Infineon

Isolated gate drivers are a crucial design element that can protect our designs from over-voltage and short circuits. But how can we fine tune these isolated gate drivers to match the design requirements we need? In this episode of Chalk Talk, Amelia Dalton and Perry Rothenbaum from Infineon explore the programmable features included in the EiceDRIVER™ X3 single-channel highly flexible isolated gate drivers from Infineon. They also examine why their reliable and accurate protection, precise and fast on and off switching and DESAT protection can make them a great fit for your next design.
