Working Principle of ADP5350ACPZ-1-R7

In battery management systems, current sharing is essential in order to maximize the efficiency and life of the battery. The working principle of the ADP5350ACPZ-1-R7 is based on the principle of current sharing. By using a low-quiescent current low-dropout (LDO) regulator and high-side/low-side current sharing, the PMIC is able to achieve maximum efficiency in the battery stack.

The ADP5350ACPZ-1-R7 works by distributing the load current among the necessary cells in the battery stack. To determine the current distribution, the PMIC uses a loop compensation circuit that monitors the voltage of each individual cell. This is done by comparing the voltage of each cell against the target value. Based on this comparison, the PMIC can calculate the load current that needs to be shared between the cells, and can adjust the voltage accordingly.

The ADP5350ACPZ-1-R7 also provides system protection features to ensure the safety and reliability of the battery stack. It monitors the temperature of the battery stack, and will shut down the system when the temperature exceeds a certain limit. It also features a fast charge, discharge and pack disconnection system, which helps to avoid overcharging and deep discharge of the battery.
