UMFT231XC-01

UMFT231XC Datasheet Version 1.0 Document Reference No.: FT 000521 Clearance No.: FTDI 273 Future Technology Devices International Ltd Datasheet UMFT231XC USB to UART with Battery Charger Support UMFT231XC is a USB to UART development module with battery charging support. 1.1 Features 1 Introduction UMFT231XC is a development module designed The UMFT231XC is fitted with a FT231XS. For a primarily for evaluating the battery charging full list of the FT231Xs features please see the feature of FTDIs X-Chip range of USB-interface FT231X datasheet which can be found at the FTDI bridging ICs. This module is suitable for charging website. single cell lithium-ion batteries. In addition to the features listed in the FT231X datasheet, the UMFT231XC has the following UMFT231XC utilises an FT231XS and a battery features: charging IC. FT231XS is one of the devices from FTDIs range of USB interface bridging IC devices. Configured with a LTC4053EDD lithium-ion FT231X is a USB to UART interface with a battery battery charger charger detection feature, which can allow 3 way 3.5mm screw terminal for connecting a batteries to be charged with a higher current from battery to the module a dedicated charger port (without the FT231X being enumerated). Thermal regulation safety feature The module includes a LTC4053EDD, which is a 10 pin 0.1 female header used for UART lithium-ion battery charger with thermal signals, 12 pin 0.1 female header for Power regulation. FTDI X-Chips are designed to operate and control with battery charger chips, such as the Status LEDs LTC4053EDD, to facilitate charging a battery of a device via USB slave port, with either 1 Amp of Mini USB-B connector current from a dedicated charger port or with up to Power MOSFET for suspending power supplied 500mA from a USB host without violating USB to an external circuit from USB bus when in compliance regulations. The X-Chip family are USB suspend mode designed to implement this feature without the requirement of external MOSFET or controller chips to regulate the current divider network of the LTC4053 chip. Applications include The on-chip MTP ROM of the FT231XS is Prototyping and evaluating battery charging of programmed by default to support this specific a device via a USB port battery charging application. The MTP ROM can be USB to UART communications reconfigured to allow for adjustments using FT Prog. FT Prog is available for free download from the FTDI website. Use of FTDI devices in life support and/or safety applications is entirely at the users risk, and the user agrees to defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting from such use.
