MIC4555YML-TR Description

Short technical summary and product information.

The MIC4555YML-TR from Microchip Technology is a versatile digital level shifter featuring a 50mA Low Dropout Regulator (LDO) specifically designed for SIM card interfaces. It provides three high-speed level shifters for SIM card signal translation, supporting clock rates greater than 5MHz.

 

The device integrates a 50mA LDO to power the SIM card, simplifying design by eliminating the need for a separate power device. It offers flexible voltage options, powering 1.8V or 3V SIM cards up to 50mA. The input voltage range is 2.7V to 5.5V, and the controller voltage range is 1.6V to 5.5V.

 

With 8kV ESD protection on SIM contact pins, the MIC4555YML-TR ensures robust performance. It is specified to operate within a junction temperature range of -40°C to +125°C. The component is housed in a compact, 16-pin MLF® package measuring 3mm x 3mm, suitable for surface mounting.

 

Applications for this level shifter include SIM card interfaces for 3G/4G systems, wireless PC cards, and smart card readers. Its design simplifies the overall SIM card interface circuitry.
