Introduction

The BD8664GW-E2 is an ultra-low power IC that can be used to charge and power lithium-ion batteries. It is a multi-functional IC, which combines low-power electronics and low-power components to create a comprehensive solution for battery-powered devices. This IC is ideal for use in mobile applications, including smartphones, tablets, and portable media players.

Application Field

The BD8664GW-E2 is a PMIC - Battery Chargers, which is ideal for use in mobile applications. It is designed to support a wide range of input sources and output currents, making it suitable for a number of different battery types, including lithium-ion, nickel-metal hydride and lead acid. It is also designed to provide accurate charging and temperature control, making it suitable for a range of environmental conditions.In addition to these features, it also features a low quiescent current and low fault detect level, which make it highly efficient and reliable. This makes it a great choice for any low power application, as it ensures a consistent output and can be used in a wide range of conditions.

Working Principle

The principle behind the BD8664GW-E2 is relatively straightforward. It begins by taking in a voltage from the power source that is applied to the input terminal. This voltage is then regulated by an internal control block and then regulated again by an internal switching block.This switching block then converts the regulated voltage into a constant current that is supplied to the battery. After the battery is charged, the voltage is then re-regulated and the power is turned off. The regulation is kept constant until the battery is fully charged or until the input voltage is no longer sufficient for charging.

Safety Features

The BD8664GW-E2 also has several safety features built in. It has an over-voltage protection circuit, which ensures that the voltage applied to the battery does not exceed the safe level. In addition, it has an over-current protection circuit, which limits the current supplied to the battery in the event of an over-current situation. These safety features ensure that the BD8664GW-E2 is safe to use and prevents damage to the battery and other components on the device.

Conclusion

The BD8664GW-E2 is an advanced PMIC - Battery Chargers that is ideal for use in low power devices. It is designed to provide efficient and reliable charging and has several safety features built in. In addition, it is designed to support a wide range of input sources, which makes it suitable for a number of applications. It is easy to install and use, making it a great choice for any low power device.
