The MIC4555 is a digital level shifter with a 50mA LDO for SIM card interfaces. There are three high-speed level shifters for SIM card signal translation. The level shifters are designed to support high-speed clocking up to 5MHz. The 50mA LDO provides power for the SIM card to eliminate the need for a separate power device. This simplifies the design of the SIM card interface.
Additional Features
Powers 1.8V or 3.0V SIM up to 50mA
Input voltage range: 2.7V to 5.5V
Controller voltage range: 1.6V to 5.5V
Supports clock rates up to 5MHz
8kV ESD protection on SIM contact pins
