NEX10000UBZ

Overview

The NEX10000UBZ is a power supply IC providing programmable positive and negative output voltages for TFT-LCD panels. It integrates an LDO regulator, boost converter, and negative charge pump. The device operates from a single lithium-ion, Ni-Li, or Li-Po battery with an input voltage range of 2.7V to 5V. Key electrical parameters include a maximum output current of 80 mA, an output voltage range of 4 V to 6.5 V with ±1% accuracy, and a typical input capacitance of 4.7µF. It features ESD, UVLO, and OTSD protection, excellent transient response, and integrated active output discharge.

Feature Summary

• Provides programmable positive and negative output voltages specifically designed for TFT-LCD panel biasing
• Integrates an LDO regulator, boost converter, and negative charge pump within a single compact package
• Features integrated active output discharge functionality for rapid power-down sequences
• Includes comprehensive protection mechanisms such as ESD, Under-Voltage Lockout (UVLO), and Over-Temperature Shutdown (OTSD)

Applications

• Smartphone TFT-LCD panels
• Tablet TFT-LCD panels

Procurement Notes

Verify the specific suffix (e.g., Z) against official Nexperia documentation to confirm packaging details and RoHS compliance status. Confirm availability as some distributors may list this part as discontinued or end-of-life. Ensure the ordering code matches the required tape and reel specifications for your manufacturing process.

Selection Notes

Select this component when designing portable devices requiring a single-cell battery solution for LCD bias generation. It is suitable for applications needing both positive and negative rails with high precision. Consider the 1.16mm x 1.96mm WLCSP package constraints for tight PCB layouts. Verify that the 80mA output current meets the display driver requirements.

Part Context

This part belongs to the NEX10000 series of power management ICs from Nexperia. The series is engineered for mobile consumer electronics, specifically targeting the power needs of thin-film transistor liquid crystal displays. It replaces discrete solutions by integrating multiple conversion stages into a small form factor.

Replacement Considerations

Check for NEX10000AUB or NEX100001UB variants if different packaging or slight parameter variations are acceptable. Verify pin compatibility before substitution.
