The MAX1898 is a highly advanced and efficient charging solution for 1-cell lithium-ion (Li+) batteries, when coupled with an external PNP or PMOS transistor.
The MCP73831 devices are extremely sophisticated linear charge management controllers for use in situations with limited space and a tight budget. The MCP73831 devices are offered in a 5-Lead SOT-23 configuration.
Alpha and Omega Semiconductor Limited has announced the release of a 30V MOSFET AONS30300 that features a high Safe Operating Area (SOA) capability making it ideally suited for demanding applications such as hot swap and eFuse.
The use of solar power in hobby electronics is highly understated. Its use is not widespread (outside dedicated projects) since it has a reputation of being too low-power to be useful.
The TMP5000 module is a breakout board that contains the TP5000 single-cell LiPo battery charging IC and the associated peripheral components that set charge parameters.
The TP5100 is an integrated Lithium battery charger that has a switch mode buck topology. It has all the integrated functions to charge a single or dual cell Lithium battery, along with a few peripheral components.
