The BQ2084DBTRG4 is a battery management IC (PMIC) designed for applications that require accurate monitoring and management of single cell Lithium-Ion (Li-Ion) and/or Lithium Polymer (Li-Po) batteries. It is a highly advanced, single cell linear charger IC that has been optimized for small, low power devices.

Applications:

The BQ2084DBTRG4 is used in a wide range of applications, including those demanding the highest level of accuracy and reliability. These include portable devices such as mobile phones, digital cameras, digital audio players and other electronic gadgets. The BQ2084DBTRG4 is also used in automotive and industrial applications where accurate battery monitoring is important.

Working Principle:

The BQ2084DBTRG4 is a monitoring and control system. It intelligently monitors and controls the flow of energy between the battery, power source and load. The BQ2084DBTRG4 accurately monitors the charge/discharge rates, voltage, temperature, remaining capacity and other parameters of a single cell Li-Ion/Li-Po battery through a programmable register interface. It is designed to protect the battery from overcharge, over discharge and other threats.

The BQ2084DBTRG4 is based on a Reset Voltage Regulation (RVR) architecture, where the IC sets the battery voltage to a pre-defined value by controlling the charge current. The RVR architecture is capable of delivering very accurate voltage regulation over a wide range of battery types and load conditions. The BQ2084DBTRG4 also features a Battery Low Voltage Disconnect (BLVD) circuit to ensure safe operation of the battery.

The BQ2084DBTRG4 features a programmable register interface for monitoring and control. The user can program the device for charging and discharge characteristics, safety limits, and other criteria. The IC is designed for easy integration into existing systems as well as standalone operation.

The BQ2084DBTRG4 is a highly accurate, low power battery management IC ideal for applications that require reliable, low-cost monitoring and control of single cell Li-Ion/Li-Po batteries.
