PMIC - Battery Management:BQ7693006DBTR Application Field and Working Principle

PMIC (Power Management Integrated Circuit) is a semiconductor device that combines multiple power control functions into one chip and works on the system. PMIC products are widely used in all kinds of portable electronic products, ranging from smart phones, computers and peripherals, medical devices, security devices to energy-saving lighting and e-transportation. With the popularity and development of various kinds of portable electronic products, PMIC products have become an important part of the industry.

The BQ7693006DBTR is a battery management and protection device from PMIC. It is especially designed for the tight power control and battery management needs of wearable applications. It is well suited for wearable applications such as smart watches, fitness watches and other designs.

Application Field

The BQ7693006DBTR integrates all the essential functions including battery monitoring, charging and protection on a single-chip to make battery management easier. It is a perfect solution for wearable applications because of its small package IC which can monitor different types of cells like Li-ion, Li-IV, Li-polymer and other cells.

The integrated charger can charge a connected battery from USB or existing power sources even at low current or low voltages. This can make the wearable device \'s battery last longer. The device also features an auto power-down function to cutoff battery drain-down when not in use. All the features of BQ7693006DBTR make it an ideal choice for wearable applications.

Working Principle

The working principle of the BQ7693006DBTR is based on the charging and discharge monitoring of the battery. When the power supply is connected, the device\'s built-in charger allows it to be charged. When the battery is charged, the IC monitors the charge and discharge current of the battery. The device continuously monitors the battery cells current and temperature. The protection mechanism protects both the device and the battery. In case of over voltage, over temperature or over current, the device will take appropriate control measures to protect the safety of the system.

The BQ7693006DBTR also includes a wide range of low-power features like, differential voltage output and low-quiescent current sensing cellular, that help improve device performance and power efficiency of the system. The device features can be further optimized with the aid of DTM (Direct Test Mode) which enables a range of parameters to be programmed for the best performance in different conditions.

Conclusion

PMIC is a critical component that combines multiple power control functions into one chip to meet the needs of different applications. The BQ7693006DBTR is a battery management device designed for wearable applications. It integrates all the essential functions such as battery monitoring, charging and protection on one chip. The device also features an auto power-down function to cut off battery drains and a wide range of low-power features to improve power efficiency. The protection mechanism is also included to ensure the safety of the system. All these features make the BQ7693006DBTR an ideal choice for wearable applications.
