NVT4555UK SIM card interface level translator and supply voltage LDO
The NVT4555 device is built for interfacing a SIM card with a single low-voltage host side interface. The NVT4555 contains an LDO that can deliver two different voltages, 1.8 V or 2.95 V from typical mobile phone battery voltages up to 5.25 V and three level translators to convert the data, RSTn and CLKn signals between a SIM card and a host microcontroller.
The NVT4555 contains one voltage select pin (CTRL) to select either 1.8 V or 2.95 V for SIM card power supply and one active HIGH enable pin (EN) to enable normal operation. The NVT4555 is compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart card interface requirements
