LP8727TME-B/NOPB

Specialized Overview

The LP8727TME-B/NOPB is a specialized power management integrated circuit designed for Micro and Mini USB interfaces. It integrates a high-voltage charger capable of handling up to 28V input, alongside a complete USB transceiver. The device supports USB On-The-Go (OTG) functionality, allowing the system to act as either a host or a peripheral. Key electrical parameters include an operating voltage range of 2.6V to 5.5V for the core logic and a maximum input voltage of 28V for the charging section. It features a 25-pin WFBGA package with dimensions suitable for portable applications.

Specialized Feature Summary

• Integrates a robust 28V charger stage for direct connection to high-voltage USB sources
• Includes a full-speed USB 2.0 transceiver with built-in overvoltage protection
• Supports USB On-The-Go dual-role operation for flexible host and device connectivity

Specialized Applications

• MP3 players and portable media devices
• Portable navigation systems
• Smartphones and mobile phones requiring OTG support

Specialized Procurement Notes

Verify the specific suffix 'TME' against the manufacturer's current datasheet to confirm pinout and thermal characteristics. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with official Texas Instruments documentation to avoid confusion with similar LP8727 variants that may have different packaging or feature sets.

Specialized Selection Notes

Select this component when designing systems that require direct integration of USB charging and data communication in a single IC. It is appropriate for space-constrained portable electronics where board real estate is limited. Consider the 28V input tolerance if the design environment involves potential voltage spikes from external USB hosts or chargers.

Specialized Part Context

This part belongs to the LP8727 family of USB interface controllers. It is distinct from general-purpose PMICs like the LP8720 or LP8725, which focus on multi-rail voltage regulation rather than USB-specific signaling and charging protocols. The LP8727 series is tailored specifically for multimedia and mobile applications needing unified USB connectivity solutions.

Specialized Replacement Considerations

Direct replacements are limited due to the specific integration of the 28V charger and USB transceiver. Check for LP8727TLE-B/NOPB or other suffix variations within the same family for minor packaging or temperature grade differences. No generic cross-model substitutes exist; alternative designs typically require separate charger and PHY components.
