5-channel (3 +V and 2 -V) hot-swap reference design

This article presents a five-channel hot-swap circuit that handles both positive and negative input voltages with sequential turn-on. The unique configuration allows two negative-voltage channels not protected by circuit breakers, in addition to three positive-voltage channels, to be controlled by a single MAX5927A positive-voltage hot-swap controller. The included test data verifies that the circuit meets the described load and power-sequencing requirements of the five channels.

High-performance MCU reference design for EV/HEV battery management systems

System example of an active cell balancing battery management system. The TMS570LS0432 microcontroller commands the EMB1402 EVM to monitor the battery cells and perform charge/discharge from one battery cell to an external 12V power supply. Users can view battery status and control battery balancing through a GUI running on the host PC.

Open source plankton monitoring and analysis equipment PlanktoScope

Plankton help remediate 30-50% of the world's carbon dioxide and provide the foundation for the global food chain, making up the world's largest daily movement of biomass as it travels across the ocean. The shapes, colors, and movements of these billions of creatures are as vast as the oceans that sustain them. Understanding plankton is crucial to understanding the world around us and our impact on it.

One obstacle to this type of research is the sheer size of the area to be explored, as well as limited resources for research fleets and specialized equipment. By developing a method to scale up high-quality visual exploration and documentation, we can greatly increase our understanding of the complex web of life around us, and how we in turn influence it.
