Supercapacitors are increasingly being used in a number of applications in electric vehicles, transportation equipment, industrial machinery and utility grids. In the MAXREFDES1215, a supercapacitor-based energy harvester is demonstrated using the MAX17220. The circuit uses a supercapacitor to provide backup energy. The first stage of the circuit charges a supercapacitor, and the second stage of the circuit regulates the voltage from the supercapacitor to supply various sensors with a steady output voltage. In this system, the MAX17220 is used for regulating the output voltage from the supercapacitor.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) through power-sourcing equipment (PSE) or midspan, and has many advantages over traditional methods of delivering power.

Onboard sensors can be employed to allow predictive maintenance, shorten technical troubleshooting time, and reduce overall energy consumption. Long battery life allows the smart damper to run for many years without the need to spend time and money on battery replacement.
This document describes a circuit that uses three MAX17541G buck converters and one MAX17504 step-down DC-DC converter. The circuit is arranged so that each buck converter uses the same input with four separate outputs. Each output has a different power specification. The MAX17541G regulator and features are given first, followed by the MAX17504 features.
The FDC2214 proximity and capacitive sensing design demonstrates how to use TI's capacitive sensing technology to sense and detect the presence of various objects. This design is a complete hardware and firmware solution. The firmware processes data from a proximity sensor and two capacitive touch buttons via the FDC2214 to determine whether an object is within the target sensing area. A dedicated colored LED lights up whenever the device detects an object in close proximity to the board or detects a button press. This design is powered by one AA battery.

In battery-powered water meters, battery life over several years is key. One of the challenges is to continuously measure water flow information while using as little power as possible. The Scan I/F sensing peripheral integrated on the ultra-low power MSP430 microcontroller solves this problem. In the water meter design, the scan interface coupled to the LC rotation detection sensor continuously detects the rotation of the thruster while the rest of the microcontroller is in a low-power sleep mode. This reference design demonstrates how to use the scan interface to achieve ultra-low power consumption (versus the same detection method using external circuitry).
