NCP362BMUTBG

Power Supply Controllers, Monitors Overview

The NCP362BMUTBG is a power supply controller designed for overvoltage protection in USB applications. It integrates an overcurrent protection controller, TVS diodes for VBUS lines, and low capacitance ESD diodes within a single package. The device operates with a voltage supply range of 1.2V to 20V. It is housed in a 10-UDFN (2.5x2) package, providing a compact solution for protecting USB ports from electrical faults while maintaining signal integrity through integrated transient suppression components.

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'MUTBG' against the manufacturer's official datasheet to confirm pinout and thermal pad configuration. Ensure the ordering part number matches the exact package outline dimensions specified in the documentation. Cross-reference the component marking code with the official identification guide to prevent counterfeit substitution during procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when a unified solution for USB power protection is required. It combines active control logic with passive protection elements, reducing board space compared to discrete designs. Consider the 1.2V to 20V operating range to ensure compatibility with the target system's power rails. Verify that the 10-UDFN package fits the available footprint constraints.

Power Supply Controllers, Monitors Part Context

This component belongs to onsemi's power management IC portfolio, specifically targeting USB interface protection. It serves as an integrated alternative to separate OVP, OCP, and ESD devices. The integration simplifies design complexity by consolidating multiple protection functions into a single small-footprint package suitable for portable electronics.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct substitutes within the NCP362 family, such as NCP362CMUTBG, verifying functional equivalence and pin compatibility. Confirm that any replacement maintains the same 10-UDFN package and electrical specifications for VBUS protection.
