AAT3663IWO-4.2-2-T1 is a battery charging solution that incorporates a boost converter with a high-efficiency LED driver into a single-package device. The integrated circuit (IC) operates with an input voltage range of 4.2V to 6.0V and delivers plus or minus 4.2V to 6.0V output voltage using a 2A sink from the battery and an adjustable frequency of up to 1MHz. This enables the AAT3663IWO-4.2-2-T1 to be used in a wide range of applications, including mobile phones, tablets, and wearable devices.

The AAT3663IWO-4.2-2-T1 covers both charging and discharging of the battery with a unique, dual-mode control system. In discharge mode, the device provides up to 2A sink current from the battery. During charging, the boost regulator draws up to 2A source current out of the battery and boosts it to the set output voltage. This allows the battery to reach a maximum charge incrementally while limiting any overcharging.

The integrated, high-efficiency LED driver features a 100% duty cycle, making it suitable for applications inducing an enhanced-brightness display mode. The driver also incorporates an internal boost regulator that is adjustable from 0 to 6.0V, allowing it to provide independent control of the LED-supply voltage rail.

The AAT3663IWO-4.2-2-T1 also includes a programmable over-voltage protection (OVP) feature, which shuts down both the main boost regulator and LED driver in case of any unwanted increase in input voltage. This feature helps protect from any potential catastrophic events, such as a short circuit on the battery or the charger itself.

In addition, the AAT3663IWO-4.2-2-T1 includes a thermal protection feature that shuts down both the main boost regulator and LED driver when the IC temperature exceeds 165℃. This protects the device from potential thermal run-away or device damage due to excessive current.

The AAT3663IWO-4.2-2-T1 also features external shutdown logic, allowing the system to quickly shut down the device in case of any fault or emergency condition. In addition, the device’s under-voltage lockout (UVLO) circuit protects the IC from damaging current conditions by preventing it from operating below the set threshold voltage.

Overall, the AAT3663IWO-4.2-2-T1 is a highly efficient and reliable power management solution for battery charging and LED driver applications. With its wide input voltage range, adjustable output voltage, dual-mode control system, and various protection features, the AAT3663IWO-4.2-2-T1 provides the perfect solution for a variety of consumer and industrial applications.
