What is a lithium ion linear Charger?

Li-Ion linear charger... Battery management ICs play an important role in ensuring the safety of users, while making sure they get the most out of their battery-powered devices. Battery management solutions require accurate voltage, current, and temperature measurements to determine the exact state of charge of batteries and battery packs.

What is a lithium ion battery IC?

These devices offer charge currents from as little as 200 mA to 1.2 A and are ideal for any rechargeable lithium-ion battery. The ICs provide high measurement accuracy (voltage, current, and temperature) and cell balancing functions with low power consumption.

What is Infineon battery protection?

For that, Infineon ofers a wide range of battery protection solutions that, under stressful conditions, increase lifetime and eficiency of lithium batteries. The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating.

What is the charge voltage & current limitation?

The charge voltage is fixed at 4.2 V, and current limitation can be programmed using a single resistor connected between PROG pin and GND. The charge cycle is automatically terminated when the current, which flows to the battery, is 1/10 of the programmed value.

Why does a load pre-charge circuit limit inrush current?

Inrush currents arise during the turn on, mainly when the battery is first connected to the load. The inrush currents can get high enough to either destroy the protection circuit or to blow of the protection fuse. A load pre-charge circuit would limit the inrush current during the turn on phase and protect both the battery and the load.

What does a battery protection circuit do?

The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
