... P-Channel logic level MOSFET switch. NOTE: This function is driven by an open-drain to ground with no internal pull-up, this is specially designed to aid battery charging applications. UMFT240XA connects an on-boardl 47K pull-up to each CBUS and DBUS pin. Transmit data LED drive – open drain pulses low when transmitting data via USB. Receive data LED drive – ...

... Solder Link Modifications 5.2 The UMFT240XA has two solder links fixed to the top side of the PCB. These solder link can be adjusted by removing the solder linking the two PADs to produce an open or by placing a solder bridge to produce a short. By default the UMFT240XA has both solder links shorting their pads. To allow for enhanced flexibility of this module remove both solder links and wire the header pins according to the power setup required ...

... TTL Mode Solder Link JP1 - Closed Figure 5.1 – Bus Powered Configuration A bus powered configuration draws its power from the USB host/hub. The UMFT240XA is configured by default bus powered mode. Figure 5.1illustrates the UMFT240XA module in a typical USB bus powered design configuration. By default solder bridge connections link VCCIO to 3V3OUT, and VCC to VBUS ...

... Driving a level to the RESET# pin of the UMFT240XA will override the effect of this voltage divider. When the FT240X is in reset the USB DP signal pull-up resistor connected to the data lines is disconnected and no current can flow down the USB lines. An example of interfacing the FT240X with a Microcontroller‟ ...
