EvilmonkeyzDesignz | Fully Integrated Ballast Control IC #componentscloseup @EvilmonkeyzDesignz | Uploaded April 2024 | Updated October 2024, 12 hours ago.
Here is a fully integrated ballast control integrated circuit. Let's open it up to take a closer look at the silicon.
-
To get to the silicon in this part, I'll use hot air to weaken the black epoxy to the point where I can start to chip away at it. Once the silicon chip is removed, I'll use a #PCBcoin to move it over to the microscope for further viewing.

This chip is the IR2157 from International Rectifier and has a lot of interesting features, including some sections that are isolated from the rest of the circuits. This chip also has a Pac-man for the copyright symbol, and a ghost for the Maskworks M.
A few of the pins on this IC are rated for voltages up to 625V, which is why they require isolation.
If you want to learn more about this part, I would Highly recommend checking out the datasheet. It's well written and includes a nice block diagram of the internal components.
