F75204
1 General Description
The F75204 is the combination of Hi-Speed USB data switches and a USB Dedicated Charger
identification circuit. The F75204 support most of the USB Battery Charging Specification worldwide,
including BC 1.2, Apple® charging spec (for i-Pad & i-Phones) and specs for Samsung Galaxy Tab. The
F75204 also equipped with a control output to control peripheral power components.
A digital input CB is able to control the mode configuration of F75204. In transmission mode, the
F75204 acts like a USB bridge which connects the route between the USB Host and the USB Device,
and allows device using CDP mode to charge the handheld devices; in the charger mode the F75204
can automatic detect the device and provide correct acknowledge signal to the device that is going to be
charged, even if the computer system has been shut down.
By setting the USB Data pins (D+/D-) to the required voltage levels, the charging device recognize
the voltage levels, and starts to draw the current to charge. The F75204 are equipped with a control
output (CEN or CEN#) allows users to control the peripheral power management device which controls
the charging current.
The F75204 Series enhanced ESD protection up to ±8kV on the DP and DM. The F75204 is
available in a MSOP-8 Package and is allow working over the 0°C to +70°C temperature range.
