MIC4555YML-TR

Translators, Level Shifters Overview

The MIC4555YML-TR is a bidirectional voltage level translator manufactured by Microchip Technology. It features one circuit with a single channel, housed in a 16-MLF® (3x3) package. The device supports VCCA voltages from 1.6 V to 5.5 V and VCCB voltages from 2.7 V to 5.5 V. It includes an integrated 50mA Low Dropout Regulator (LDO) specifically designed for SIM card interfaces. The component operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Translators, Level Shifters Feature Summary

• Integrates a 50mA LDO regulator tailored for SIM card interface power requirements
• Provides bidirectional translation between low-voltage logic domains (1.6V–5.5V) and higher voltage domains (2.7V–5.5V)
• Utilizes high-speed digital level shifting for efficient signal transmission

Translators, Level Shifters Applications

• SIM card interface circuits requiring voltage translation and local regulation
• System-on-module designs needing isolated power domains for smart card readers
• Embedded systems interfacing low-voltage processors with 3.3V or 5V peripheral devices

Translators, Level Shifters Procurement Notes

Verify the specific suffix YML against the manufacturer's current datasheet to confirm pinout and thermal pad configuration. Ensure the design accounts for the integrated LDO's current capability when powering SIM cards. Confirm RoHS3 compliance status matches project environmental requirements. Check for any recent Product Change Notifications regarding packaging or manufacturing location changes.

Translators, Level Shifters Selection Notes

Select this component when a compact solution is needed for SIM interfaces that requires both level shifting and local power regulation. The integrated LDO reduces external component count compared to discrete solutions. Verify that the target application voltage ranges fall within the specified VCCA and VCCB limits. Consider the 16-MLF package size constraints during PCB layout planning.

Translators, Level Shifters Part Context

This part belongs to the MIC4555 series of digital level shifters. Unlike standard translators, this series integrates a power management feature (LDO) to support specific interface standards like SIM cards. It serves as a bridge between different voltage domains in portable and embedded electronics, simplifying board space and design complexity.

Translators, Level Shifters Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering alternative vendors, as pinouts and internal LDO characteristics may differ significantly.
