BQ27500DRZR-V100 is a battery management integrated circuit developed by Texas Instruments specifically designed for single-cell li-ion/li-polymer battery applications from 1.6V to 5.5V. It is an ideal choice for use in a wide range of portable, and other applications that require application specific and analog circuits to manage battery resources such as chargers and power supplies and adjust applications such as gauge and other sensing systems. The integrated circuit includes an analog and digital life-calculation monitoring of the battery, an integrated FETS system to control power distribution and an embedded processor to interpret all of the inputs.

The BQ27500DRZR-V100 is packaged in an 8-pin WSON package and integrates a dedicated fuel gauge and battery monitoring dashboard, as well as embedded safety features such as overcurrent shutdown and battery capacity estimation.

The integrated fuel gauge on the BQ27500DRZR-V100 is capable of accurately tracking the battery capacity and voltage, with a reported accuracy of 1.4%. The integrated battery gauge is capable of accurately predicting the remaining battery capacity with a reported accuracy of 3.7%. It will also provide an accurate prediction of the temperature, current and voltage parameters as well as an estimate on the remaining charge time to empty or full state.

The integrated digital processor will interpret all of the inputs from the battery, charger and the FETS system to process and prioritize the full power distribution needs of the connected devices. It is also responsible for embedding safety measures such as controlling the voltage and current output to avoid any unexpected power surges and overcurrent scenarios that could damage the circuitry or cause safety hazards. At the same time it will track the battery usage and temperature, sending notifications of any potential abnormal conditions or temperature changes.

The integrated FETS system on the BQ27500DRZR-V100 will provide the power distribution control across the connected devices, allowing the user to assign priority to connected devices and maintain the power draw of the connected devices in the most efficient way possible. For example, the FETS system can be used to prioritize the charging of the handset first, followed by the charging of an accessory and lastly the charging of a power bank. This not only ensures seamless power delivery to all of the connected devices, but also ensures that the safety features will be triggered when required.

The BQ27500DRZR-V100 is ideal as a solution for a wide range of embedded devices, such as: smartphones, tablets, wearables, handheld gaming devices, smart meters and more. The platform allows for the integration of the power distribution needs of the connected devices and a value addition of having the systems monitored and safely shut off in case of a power spike or an issue with one of the power sources on the device. It provides an accurate estimation of battery capacity, and allows adjustments and prioritization of the power distribution needs of the system in an effective and efficient manner.

In conclusion, the BQ27500DRZR-V100 is a powerful integrated solution for battery management, providing an efficient and safe power distribution system. It offers an enhanced battery life-calculation monitoring of the battery, an integrated FETS system to control power distribution and an embedded processor to interpret all of the inputs. The integrated FETS system allows for the integrated and prioritized power delivery for the connected devices, and the integrated digital processor monitors the battery and power output and reports any potential issues. The wide application range makes the BQ27500DRZR-V100 an ideal solution for many embedded and portable applications.
