Introduction

The AUR9801CGD is an advanced universal regulating device that supports a wide variety of battery chargers. The device contains a universal digital logic and analog circuits to facilitate the regulation of battery charging. This device was developed to support applications that either require fast charge rates, or those that have to constantly adjust the output voltage to extend the battery life or support different batteries or operating conditions.

PMIC - Battery Chargers

PMIC - Battery Chargers are used to recharge a wide range of batteries and protect them from damage during the charge cycle. The AUR9801CGD is an advanced universal regulating device that supports a wide variety of battery chargers. This device is designed to improve battery performance by reducing the charge time, increasing the battery life, charging different types of batteries, and allowing for the adjustment of output voltage in order to support various operating conditions.

AUR9801CGD Features and Specifications

The AUR9801CGD is a 3-terminal integrated circuit with a wide range of features, some of which include: • Support for low-Voltage and high-Voltage systems• High-Impedance (High-Z) input stage• Zero Power Start up• Digital Logic level monitoring• Internal power stage • Charge current setting up to 4 A• Low voltage drop ability• Soft start function• Thermal protection• Protected soft-start mode• Protection against over-charge and over-voltage• Extended temperature range of -40C to +85C

Working Principle

The AUR9801CGD supports three modes of operation: high-voltage, low-voltage, and soft-start. In high-voltage mode, when the input voltage is greater than the set voltage, the charge is automatically activated. In low-voltage mode, the device will automatically turn off if the input voltage is lower than the set voltage. In soft-start mode, the device gradually increases the output voltage until the set voltage is reached. The AUR9801CGD uses its internal digital logic to monitor the charge level, output voltage, and temperature. The device will automatically shut down if the temperature rises above a certain threshold, or if the charge level exceeds the maximum set voltage. The device is also capable of automatically recharging the battery after it senses a drop in the output voltage.

Conclusion

The AUR9801CGD is an advanced universal regulating device that supports a wide variety of applications. The device is designed to improve battery performance by reducing the charge time, increasing the battery life, charging different types of batteries, and allowing for the adjustment of output voltage in order to support various operating conditions. The AUR9801CGD supports three modes of operation, has a wide range of features, and uses digital logic to monitor the charge level, output voltage, and temperature.
