STEVAL-ISA076V1：Battery charger demonstration board with integrated power switch for Li-ION/Li-POLYMER based on the L6924D
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.
