VA7208 Advanced Linear Charger IC for Lithium-ion and Lithium-polymer Battery FEATURES 4.5V to 12V input voltage range „ Ideal for single (4.2V) Li-ion or Li-polymer battery packs „ „ „ „ „ „ „ „ „ combines high-accuracy current, voltage regulation, charge termination, and charge status indication in a single 8-pin IC. It is the best suitable device to be used in PDA, mobile phone, and other portable devices. VA7208 monitors the battery charging status by detecting the battery voltage. VA7208 charges the battery in three phases: conditioning, constant current and constant voltage. If the battery voltage (VBAT) is below the preconditioning voltage threshold (VMIN), VA7208 precharges the battery using a low current.
