UMFT231XC USB to UART
Future Technology

UMFT231XC is a development module designed
primarily for evaluating the battery charging
feature of FTDI’s X-Chip range of USB-interface
bridging ICs. This module is suitable for charging
single cell lithium-ion batteries.
UMFT231XC utilises an FT231XS and a battery
charging IC. FT231XS is one of the devices from
FTDI’s range of USB interface bridging IC devices.
FT231X is a USB to UART interface with a battery
charger detection feature, which can allow
batteries to be charged with a higher current from
a dedicated charger port (without the FT231X
being enumerated).
The module includes a LTC4053EDD, which is a
lithium-ion battery charger with thermal
regulation. FTDI X-Chips are designed to operate
with battery charger chips, such as the
LTC4053EDD, to facilitate charging a battery of a
device via USB slave port, with either 1 Amp of
current from a dedicated charger port or with up to
500mA from a USB host without violating USB
compliance regulations. The X-Chip family are
designed to implement this feature without the
requirement of external MOSFET or controller chips
to regulate the current divider network of the
LTC4053 chip.
The on-chip MTP ROM of the FT231XS is
programmed by default to support this specific
battery charging application. The MTP ROM can be
reconfigured to allow for adjustments using
FT_Prog. FT_Prog is available for free download
from the FTDI website.
UMFT231XC is a USB to UART development module with battery charging support.
