The lithium battery management chips and switches are important components of battery application systems. Fig. 2 depicts a typical application circuit of a lithium battery management chip from Ref. [14].It mainly comprises a lithium battery, filter resistor R1, filter capacitor C1, discharging FET NM1, and charging FET NM2.
Li-ion battery charging ICs play a vital role in managing the charging process, ensuring safe and efficient power delivery to the battery. Here are some essential considerations when evaluating these ICs: Maximum charge current: The Maximum charge current determines how quickly the battery can be charged without damaging it.
This application note shows how to take advantage of Microchip’s fully integrated simple Li-Ion battery charge management controllers with common directional control to build a system and battery load sharing circuitry. The solutions are ideal for use in cost-sensi-tive applications that can also accelerate the product time-to-market rate.
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.
When charging the battery, switch off the load, and when loading the battery, switch off the charger. Alternatively use a PMOSFET, a resistor and a Schottky diode (See page 2 on how to do this). Lithium batteries can not absorb overcharge - the current must be cut off after charging. If not there could be thermal runaway.
Most Li-Ion battery chargers are based on Constant Current and Constant Voltage (CC-CV) modes. The termina-tion is based on the ratio of charge current and preset constant current (Fast Charge). If the system draws current from the battery, the charge current will never meet the termination value.
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.

It is important to efficiently charge Li-ion batteries for maximum use. First, let''s analyze the Li-ion battery charging process. The charging process can be divided into four different stages: trickle charge, pre-charge, constant-current charge, and constant-voltage charge. Figure 1 shows the charging curve of a typical lithium-ion battery.
Each method has its associated advantages and disadvantages, with the particular application (and its individual requirements) determining the best method to use. This application note focuses on the fundamentals of charging Lithium-Ion/Lithium-Polymer batteries.
