FAN5401x series lithium-ion battery charging switch has been released
According to foreign media reports, Fairchild (Fairchild Semiconductor) today announced, together with customers to develop a comprehensive USB On-The-Go (USB OTG) support FAN5401x series of USB-compatible switch to lithium-ion battery charger.
The product FAN5400 series of switch-mode topology based on the first component FAN54013 can provide up to 1.45A maximum charging current, and greater power boost USB OTG, can support at 5V 500mA current.
As portable devices become more and more demand for electricity, was forced to increase the capacity of the battery to extend the use of time. This gives designers a series of challenges, including how to reduce these larger battery charge time, to minimize heat dissipation during charging, and support for USB-OTG host functions such as enhanced features. Fairchild’s new FAN54013 basis using switch-mode topology, through the USB port or AC / DC adapter for the single or two lithium-ion (Li-Ion) battery, the charging time can be shortened, and simultaneously solve the current line with the issues related to the heat of the charger.
In addition to providing the highest efficiency of 94% of the charge beyond, FAN54013 with a set of protection features, including integration with 20V nominal input voltage, over-temperature protection, reverse current blocking, watchdog timer, and USB-compliant + / -5 % of the input current limit accuracy. Operation to obtain an integrated USB OTG boost regulator 5V 300mA to provide support, but also share the same inductive charger, thus reducing the number of external components.
FAN54013 charging device parameters and operation mode can operate at frequencies up to 3.4Mbps via an I2C interface of the program designed to increase flexibility. FAN5401x series with 1.96 x 1.87mm, 20 joints, 0.4mm pitch CSP package, the smallest on the market while providing charger and 500mA USB-OTG 5V boost switch-mode solutions.
The new products for a variety of typical applications, including mobile phones, smart phones, tablet PCs, wireless broadband focus, digital cameras and portable media / game players and other portable products in single or two lithium-ion batteries.
Fairchild with USB expertise and wide range of portable power solutions product that allows designers to design innovative and differentiated mobile products.
