The integrated circuit, often referred to as an "IC" or "chip," is a tiny device used to power different types of systems and components. ACT2804QJ-T0435 is an integrated circuit which belongs to the power management integrated circuit (PMIC) – battery management family. This article outlines the application field and working principle of the ACT2804QJ-T0435.

The ACT2804QJ-T0435 is a Charge-Voltage Li-Ion battery management IC, specifically designed for low power applications where space is a critical factor. It provides a space saving, efficient and flexible solution for Li-Ion batteries. The main application fields for this IC are portable healthcare devices, toys, smart cards and automotive.

The ACT2804QJ-T0435 has an integrated circuit which offers an embedded, multi-function, Li-Ion protection system with 2x4-level adjustable charge voltage range and several protection functions. It also offers an I2C communications interface and two configurable signal inputs/outputs, allowing for battery voltage and temperature readouts or signal controls from a host processor.

The ACT2804QJ-T0435 is a low power integrated circuit which works on the principle of Timer / Event Detection Control. The Circuit is built with an integrated programmable timer and temperature monitor. The timer specified is used to control the charge and discharge characteristics of the Li-Ion battery, while the temperature monitor helps to optimise the charging process and provides protection against overcharging.

The programmed timers detect when the battery needs charging or discharging. It then controls the parameters such as voltage, current, temperature and state of charge, so that the battery can be charged or discharged in a safe and efficient manner. The IC also has two configurable input/output pins, which can be used to control the charge and cycle functions. These pins can be connected to a host processor, allowing for signal control.

Additionally, the IC offers an advanced safety protection system with Password Lock and Halt Mode, which prevents data corruption and unintentional changes to settings. This integrated circuit also provides protection against overcharging, over-discharging, over-temperature and short circuit, ensuring complete safety for Li-Ion batteries.

The ACT2804QJ-T0435 is an advanced integrated circuit which offers an efficient and reliable solution for low power Li-Ion battery management. Its integrated programmable timer and temperature monitor, combined with its advanced safety protection systems, makes it a versatile, space saving and reliable solution for any type of battery application.
