Datasheet Summary
SIM Card Level Shifter with 50mA LDO
General Description
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. The MIC4555 is available in a tiny, lead-free, 16-pin MLF® package (3mm x 3mm), and is specified to operate from
- 40°C to +125°C junction temperature.
