Introduction

The MAX8600ETD+T device is a dedicated battery charger system which provides a complete solution to address the needs of a wide range of battery applications. It provides a small footprint and features an extremely low quiescent current to maximize battery life and minimize power consumption. The device includes a precision voltage regulator, a charge controller, and a constant-current/constant-voltage charging algorithm, eliminating the need for separate discrete components. It is available in both 3- and 4-cell configuration and can be configured up to 6A of output current in either pin-selectable or programmable version.

Application Field

The MAX8600ETD+T is ideal for applications that require mobile and portable power, such as camcorders, MP3 players, digital cameras, portable gaming devices, cellular phones, and other consumer electronics. Since the device is pin selectable, the output current can be easily configured to provide the desired output current for the application. In addition, the device provides power-on reset, over-temperature, current-limit, and voltage limit protection to maximize system safety and reliability.

The MAX8600ETD+T device is particularly useful for applications where space is limited, as it provides a very small form factor and offers high efficiency. The device can be used to charge non-rechargeable batteries, such as alkaline or non-rechargeable Li-ion batteries. The device also features a low dropout (LDO) voltage regulator, which can be used to provide a supply voltage for digital signals in the system.

Working Principle

The working principle of the MAX8600ETD+T device is based on a constant-current/constant-voltage (CC/CV) charging algorithm. The device first starts with a constant-current (CC) charging mode when the battery is connected, allowing the device to charge recent battery systems quickly and safely. The device then enters the constant-voltage (CV) mode when the battery voltage reaches the pre-programmed level, maintaining a constant output voltage for the battery system and preventing overcharging.

The device also features a number of protection features, such as over-temperature, current limit, and voltage limit. It includes a power-on reset function, which ensures that the device comes up into the correct operation state after power on. The device can be programmed to operate in either pin-selectable or programmable modes, allowing maximum flexibility for the user.

Conclusion

The MAX8600ETD+T device is designed to provide a complete solution for battery charging applications. It offers a small form factor, high efficiency, and maximum system safety and reliability. The device provides a constant-current/constant-voltage charging algorithm and a variety of protection features, allowing it to be used to charge non-rechargeable batteries as well as rechargeable ones. The device also provides a programmable option, which allows users to tailor the device to suit their specific needs.
