Introduction

The LTC4162IUFD-L40M#TRPBF is a power management IC (PMIC) designed to monitor and manage Li-ion/polymer battery packs. By integrating high-performance analog, mixed-signal, power conversion, and load switches, the LTC4162IUFD-L40M#TRPBF provides an embedded battery-management solution for protecting and balancing individual cells, as well as for charging and discharging the pack.

Application Field

The power management IC (PMIC) is suitable for applications including cellular phones, cordless phones, tablet PCs, notebook PCs, digital cameras, and other portable electronic devices. It provides excellent power system management for wide variety of portable applications, ranging from simple 2 cell configurations to multi-cell Li-ion/polymer batteries comprising up to 10 cells.By monitoring the charge and discharge cycles, the LTC4162IUFD-L40M#TRPBF can automatically detect the battery pack state and select the appropriate charge or discharge mode accordingly. In addition, it can monitor the pack voltage, temperature, and current during each stage of the charge/discharge process.

Working Principle

The LTC4162IUFD-L40M#TRPBF acts as a power controller between the battery pack and the load. It utilizes a high-resolution analog-to-digital converter (ADC) to measure the battery pack voltage, temperature, and current. It then fetches the necessary data from its internal memory and compares them with the actual values from the ADC measurement. By doing so, it can determine the battery pack state and will adjust the current and voltage accordingly to optimize the performance of the system.Moreover, the PMIC also contains a voltage regulator which maintains the output voltage within the required range by providing the exact voltage supply for the system. Aside from that, the PMIC also has a current regulator which helps to protect the system from high and low current levels.
