Description

FAN5404UCX Overview
I found it in the Tape & Reel (TR) package, which comes with everything you need.For convenience, it is included in the 20-UFBGA, WLCSP package.It appears that the device's mounting type is Surface Mount.The best way to adjust the temperature is to set it to -30°C~85°C TA.Analog IC ANALOG CIRCUIT is responsible for implementing the device.Charge the device by supplying it with Constant - Programmable current.Based on the base part number FAN5404, it is possible to find related parts for this device.There are 20 terminations in it.Hence, the battery pack is at 4.5V Max when it comes to voltage.The unit is equipped with a number of programmable features, including Current, Timer, Voltage.To operate the product, it is necessary that 20 pins be inserted into the device.The battery would need to have a voltage of 5V for the device to work.It is capable of withstanding a 6V supply voltage.Ideally, when the output voltage of the device is set to 1.8V, you will be able to achieve the highest degree of efficiency.As far as this device is concerned, it belongs to the subcategory Power Management Circuits.A supply voltage of 4V is suitable for it, because it can operate with a low supply voltage.In order to mount it, it has to align itself with Surface Mount.0.09mA is set for Vsup (maximum supply voltage).5V is the power supply setting for the part.This device can accept up to 20V volts of input voltage.As a maximum output supply voltage for this operation, the voltage must be set to 4.4V.To meet operation conditions, the maximum output current is reduced to 1.25A.

The FAN5404 combines a highly integrated switched-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery. The charging parameters and operating modes are programmable through an I2C Interface that operates up to 3.4Mbps. The charger and boost regulator circuits switch at 3MHz to minimize the size of external passive components. The FAN5404 provides battery charging in three phases: conditioning, constant current, and constant voltage. To ensure USB compliance and minimize charging time, the input current is limited to the value set through the I2C host. Charge termination is determined by a programmable minimum current level. A safety timer with reset control provides a safety backup for the I2C host. The integrated circuit (IC) automatically restarts the charge cycle when the battery falls below an internal threshold. If the input source is removed, the IC enters a high-impedance mode with leakage from the battery to the input prevented. Charge status is reported back to the host through the I2C port. Charge current is reduced when the die temperature reaches 120°C. The FAN5404 can operate as a boost regulator on command from the system. The boost regulator includes a soft-start that limits inrush current from the battery. The FAN5404 is available in a 1.96 x 1.87mm, 20-bump, 0.4mm pitch WLCSP package.
