Introduction
A single lithium-ion cell is often the battery of choice for portable equipment because of its high energy density. The 3V to 4.1V provided by a lithium-ion cell is also a good match for modern low voltage circuits, often simplifying the power supply. Despite these advantages, designers are often frustrated when attempting to design precision charging circuitry that meets battery manufacturers’ specifications. Figure 215.2 is a simple, cost-effective linear charger that satisfies these precision ...
