MSOP is a power supply monitor in a laptop who manages DPAK, a powerful regulator chip. It's a hot day "doing homework," but will the mean old CPU give the microchips a break to cool off?

Appendix pages explain the science behind the adorable story, and how thermal engineering applies physics to make our everyday electronic devices reliable.

The perfect picture book for our littlest electrical engineers and technologists to be, as well as the teachers and parents who are looking for more resources to help them.
