App note: Consideration of power MOSFETs in fast charger design

App note from Fairchild Semiconductors on power MOSFETs selection including thermal design and usage on fast chargers. Link here (PDF) The demand for battery capacitance up to 10,000mAh in mobile devices is steadily increasing as devices consume more power and offering more functionality. Large battery capacity provides longer battery run-time, but needs more time to […]

Partlist Wednesday: Lithium-polymer battery charger chips

Lithium-polymer batteriesĀ are an excellent choice for portable projects. They are relatively cheap, hold a significant charge, and last for a long time. The drawback with these batteries is that they require rather complicated charging protocols. You have to watch out for overcharging, undercharging, overheating, etc… We are looking for a standard part to use in […]
