Introduction

The AAT3672IWO-4.2-1-T1 is a battery charger IC specifically designed for low-power applications. It incorporates a high output impedance and low operating voltage, allowing the AAT3672IWO-4.2-1-T1 to charge a wide range of batteries, including rechargeable lithium-ion, nickel-cadmium, and nickel metal-hydride chemistries. The low operating voltage also allows for a very tight regulation of the charging current, improving battery consistency and endurance.

Application Field

The AAT3672IWO-4.2-1-T1 is an ideal solution for powering low-power applications such as wearable devices, handheld instruments, portable game consoles, and cameras. Its low operating voltage makes it well-suited for hand-held portable applications, while its high output impedance ensures that the batteries are not overcharged.The AAT3672IWO-4.2-1-T1 can also be used in industrial applications such as battery packs, power-supply power management, and industrial energy storage systems. In these applications, it can be used to provide dynamic power management between supplies and battery packs and improve system performance.

Working Principle

The AAT3672IWO-4.2-1-T1 features a low operating voltage and high output impedance, allowing it to charge a wide range of batteries without requiring the user to monitor the battery voltage. The AAT3672IWO-4.2-1-T1 will provide a small amount of current to begin charging the battery, which is monitored by a feedback loop. When the battery voltage reaches the set point, the charger will reduce the current output and maintain the battery voltage. The AAT3672IWO-4.2-1-T1 also features over-voltage, over-current, and over-temperature protection, providing an additional layer of safety and reliability.

Conclusion

The AAT3672IWO-4.2-1-T1 is a charger IC specifically designed for low-power applications. It offers a low operating voltage and high output impedance to allow for a wide range of charging profiles. It is well-suited for battery packs, power-supply power management, and industrial energy storage applications, and offers over-voltage, over-current, and over-temperature protection for added safety and reliability.
