STEVAL-ISA076V2: Li-Ion/Li-Pol, 1-Cell, 4 ~ 12V in

Summary

The STEVAL-ISA076V2 demonstration board is based on the L6924U which is a fully monolithic battery charger dedicated to single-cell Li-Ion/Polymer battery packs. It is the ideal solution for space-limited applications, such as PDAs, handheld equipment, cellular phones, and digital cameras.

When an external voltage regulated adapter or USB port is used, the L6924U works in linear mode, and charges the battery in a constant current/constant voltage (CC/CV) profile.

Moreover, when a current-limited adapter is used, the device can operate in Quasi-Pulse Mode, dramatically reducing the power dissipation.
