The BQ20Z80DBTR-V101, manufactured by Texas Instruments, is a battery management integrated circuit for isolated, non-isolated, single-cell lithium-ion/polymer and lead acid battery systems. Designed specifically to provide protection and accurate monitoring of the battery cell, the BQ20Z80DBTR-V101 offers features which include cell balancing, system power-on reset, cell voltage monitoring, over-discharge protection and system power-led control. Furthermore, the integrated IC supports a variety of external devices including temperature sensors, current sense resistors and switching MOSFETs.The BQ20Z80DBTR-V101 is capable of managing isolated or non-isolated systems. In an isolated system, the integrated circuit acts as a smart battery charging device, while in a non-isolated system, the device is responsible for managing the power delivery from the system to the battery. The BQ20Z80DBTR-V101 is capable of monitoring all cell voltages within a single battery, which ensures accurate charge and discharge balance. Furthermore, it can monitor the battery health and detect abnormalities such as temperature misreadings, current surges, and over-charging. Additionally, the BQ20Z80DBTR-V101 incorporates an over-discharge prevention circuit which automatically cuts off the system power supply when the charge falls below optimal levels. The integrated IC is also capable of providing system power-on reset functionality, which gives the user control of the system power on conditions.Finally, the BQ20Z80DBTR-V101 includes a special LED Control circuit, which provides LED indication of system power-on, over-discharge, charging, and end-of-charge states. This feature allows for easy visual identification of the system\'s charge and discharge states.The BQ20Z80DBTR-V101 is ideal for isolated and non-isolated lithium-ion/polymer and lead acid battery systems and offers many benefits to the user. Its battery monitoring and over-discharge protection capabilities make it an ideal choice for applications where precise charge and discharge balancing and system power-on control is needed.
