Description

The STEVAL-ISA076V1 demonstration board is

based on the L6924D battery charger system with

integrated power switch. The L6924D device is a

fully monolithic battery charger dedicated to

single-cell lithium-ion polymer (Li-Pol) battery

packs, and is the ideal solution for space-limited

applications such as PDAs, handheld equipment,

cellular phones, and digital cameras.

When an external voltage-regulated wall adapter

is used, the L6924D works in linear mode, and

charges the battery using a constant

current/constant voltage (CC/CV) profile.

When a current-limited adapter is used, the

device can operate in quasi-pulse mode,

dramatically reducing power dissipation.
