interface

temperature monitoring and protection

Description

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.
