UM8601

Overview

The UM8601 is an integrated EMI filter and transient voltage suppressor designed for color LCD interfaces. It incorporates eight independent LC filter lines combined with TVS protection to mitigate electromagnetic interference and electrostatic discharge events. The component is housed in a compact package suitable for space-constrained mobile devices, ensuring signal integrity while providing robust protection against environmental electrical stress.

Feature Summary

• Integrates multi-line LC filtering with TVS protection for comprehensive signal line defense
• Specifically engineered for high-speed color LCD interface applications
• Provides simultaneous EMI suppression and ESD/TVS clamping capabilities

Applications

• Color LCD module input protection
• Mobile phone display interface circuits
• Portable electronic device signal line filtering

Procurement Notes

Verify the manufacturer marking and part number alignment on the physical component against official Union Semiconductor documentation. Confirm RoHS compliance status through the specific datasheet revision. Ensure the supplier provides traceable origin documents to guarantee authenticity and prevent counterfeit components from entering the supply chain.

Selection Notes

Select this component when designing circuits requiring combined EMI filtering and ESD protection for multiple parallel data lines. It is appropriate for applications where board space is limited and discrete LC filters plus separate TVS diodes would exceed area constraints. Evaluate the capacitance and breakdown voltage specifications against the specific LCD controller requirements.
