Pulse charger with overcurrent protection function
LTC4052 is a fully integrated pulse charger for single 4.2V lithium ion / lithium polymer batteries. When the input voltage is 5.25V and the 0.8A current is used for fast charging, the power consumption of LTC4052 is about 280mW, while the power consumption of the linear charger solution is as high as 1.8W. Unlike switch capacitors with high efficiency and low heat dissipation using inductors, the LTC4052 is designed with no inductor. The lithium ion / lithium polymer battery charger circuit designed by LTC4052 only accounts for the area of 70mm2 and the height is less than 1.7mm. The 700mA to 2A battery charger is designed. By reducing power to the lowest level, LTC4052 can relax the requirements of the terminal device for thermal design, allow smaller packages, smaller heat dissipation airflow and smaller PCB area, and eliminate hot spots, so that no heat sink or fan is needed.

The effect of overcharge on the performance of the battery
hen the battery is full of electricity, it will cause negative capacity to be higher than positive capacity when it continues charging. The gas produced by the positive electrode is combined with the cadmium produced by the negative electrode. In general, the internal pressure of the battery will not increase obviously

The effect of overcharge on the performance of the battery
When the battery is full of electricity, it will cause negative capacity to be higher than positive capacity when it continues charging. The gas produced by the positive electrode is combined with the cadmium produced by the negative electrode. In general, the internal pressure of the battery will not increase obviously, but if the charging current is too large or the charging time is too long, the oxygen produced is too late to be consumed, which may cause the rise of the internal pressure, the deformation of the battery, the leakage of liquid and so on. At the same time, its electrical performance will also be significantly reduced.
