The FAN1589MX is a Single Cell Li-Ion Battery Charger IC, which requires an internal boost converter to support two sleep modes with extremely low quiescent current. This device is designed to be used as a voltage regulator, specifically for special purpose applications such as portable device charging and power management.

The FAN1589MX features an adjustable output voltage range of 1.8V up to 6V, with a standard switching frequency of 1 MHz. Additionally, the device includes an internal soft-start feature that eliminates large input currents during startup, and a programmable charge current limit of 1.3A. This device has a wide input voltage range from 4.3V up to 24V, making it suitable for wide range of applications. It also has a built-in over voltage protection, over current protection, over temperature protection, and an adjustable current limit, allowing for superior protection against damage to the device.

The FAN1589MX utilizes an on-chip power FET and a charge control circuit, which are used to provide the necessary power conversion and voltage regulation. When the device is connected to a battery source, the charge control circuit begins to charge the battery while the power FET generates the output voltage needed by the device. The charge control circuit then steps down the voltage from the power FET to match the voltage output of the device. This regulation is performed through a feedback loop that reads both the reference voltage and the output voltage and adjusts the power FET\'s output accordingly.

The FAN1589MX also has two sleep modes, which enable the device to maintain extremely low quiescent current. These sleep modes are activated when the device is not actively charging a battery. In the Sleep Mode 1, the charge control circuit is turned off and the device enters a standby state in order to conserve power. In Sleep Mode 2, the power FET is turned off, thereby reducing the amount of power used. The FAN1589MX can wake up from the sleep states when it is triggered internally or externally through the WAKEUP pin.

In addition, the device also contains advanced protection features, such as over current protection and over temperature protection, which provide protection against damage caused by short circuits or excessive temperatures. The FAN1589MX also has an internal temperature monitor that can be employed to ensure safe device operation.
