Etamicro Service Commitments

As a primary distributor of HALO Microchip, Etamicro will provide customers with one-stop service from selection to mass production:

• Selection Support: Based on customer platforms (Qualcomm, MTK, NXP, TI, etc.), quickly recommend compatible part numbers and alternative solutions
• Sample Service: Quick bulk sample application, supporting reference designs and schematic reviews
• Technical Support: Working with the original manufacturer's FAE to provide application debugging, EMI optimization, and reliability testing guidance
• Stable Supply: Relying on Etamicro's supply chain resources to ensure long-term stable delivery and production capacity support

Advancing Domestic Substitution

Against the backdrop of accelerating automotive electrification and intelligence, demand for automotive-grade power management ICs continues to surge. Driven by both supply chain security and domestic substitution, domestic chip manufacturers with mature mass production experience and comprehensive quality systems are entering a broad market opportunity.

Etamicro will continue to deepen its strategic collaboration with HALO Microchip, fully leveraging its localized FAE service advantages to help customers rapidly complete domestic substitution solution verification and production introduction.
