USB to RS232 Converter with 5V power output on 9th pin

US232P

FTDI chip
5V output on RS232 pin 9

OverviewSpecificationsOrdering InformationInquiryResources

This USB to RS232 converter with 5V output is ideal for POS applications and other applications as many POS devices and other RS232 devices can be powered using the 5V input via their RS232 pin 9. RS232 devices that can be powered via RS232 pin 9 do not require an external power supply by using this USB to RS232 converter with 5V output.

This USB-to-RS232 serial port converter is the ideal accessory for laptop and desktop computers that do not have a COM or DB9 serial port. Supporting Windows, Mac, Linux, and Android for rapid performance, it is a convenient connectivity solution for industrial automation systems, scientific instruments, point of sale systems, and other specialized industrial and consumer applications.

US232P can supply 5V power to the RS232 device via 9th pin

The 5V power output of pin 9 of US232P comes from the USB interface. The US232P chipset itself draws about 90mA of power. Assuming that the USB port provides 500mA power to US232P, theoretically the 5V power output of pin 9 of US232P is 410mA (500mA minus the 90mA consumed by the US232P chipset itself).

Therefore, the maximum rated current of US232P is the power supply current provided by the USB interface deducting 90mA.

Furthermore, if the connected RS232 device is running with more than 500mA, the US232P short circuit protection will activate and stop working for a few seconds.

Customization for more than 500mA of 5V power output on the 9th pin, please contact us.
