RN5T568Z-E4

Power Management - Specialized Overview

The RN5T568Z-E4 is a multi-channel Power Management IC (PMIC) manufactured by Ricoh, housed in a QFN0707-48 package. It operates within an input voltage range of 1.7 V to 5.5 V and supports output voltages from 600 mV to 3.5 V. The device delivers up to 3 A output current with a quiescent supply current of 45 µA. It functions reliably across a temperature range of -40°C to +85°C.

Power Management - Specialized Feature Summary

• Integrates multiple power management channels into a single compact surface-mount device.
• Supports wide input voltage ranges for flexible system power architectures.
• Optimized for low standby power consumption to extend battery life.

Power Management - Specialized Applications

• Power supply systems
• General purpose PMIC applications

Power Management - Specialized Procurement Notes

Verify the manufacturer designation carefully, as the RN5T568 series is also produced by Nisshinbo Micro Devices under similar part numbers. Confirm that the specific suffix matches the required Ricoh variant. Ensure compatibility with the 48-pin VFQFN exposed pad footprint during PCB layout. Check humidity sensitivity level requirements for storage and reflow soldering processes.

Power Management - Specialized Selection Notes

Select this component when a high-current, multi-channel solution is required in a small form factor. The 3 A capability suits loads demanding significant power density. Consider the 45 µA quiescent current for efficiency-critical designs. Verify that the 1.7 V minimum input voltage aligns with the source supply characteristics.

Power Management - Specialized Part Context

This part belongs to the RN5T568 series of specialized power management integrated circuits. While Ricoh produces the Z-E4 variant, Nisshinbo manufactures related versions such as the AD-E4 and AZ-E4. These devices share core specifications but may differ in minor electrical characteristics or packaging details depending on the specific manufacturer suffix.

Power Management - Specialized Replacement Considerations

The RN5T568AD-E4 and RN5T568AZ-E4 are documented variants within the same series. Cross-referencing these parts requires verifying pinout compatibility and specific electrical tolerances between Ricoh and Nisshinbo manufacturing sources.
