The U211B is a specialized integrated circuit (IC) primarily used as a phase-control circuit for motor driver applications and industrial automation. As a legacy component originally developed by Telefunken/Atmel (now under Microchip), its market profile is characterized by its obsolete status, which significantly influences its pricing and availability.

Market Pricing & Availability

* Wholesale Pricing: On B2B platforms like Alibaba, the U211B (typically the U211B-MY variant) is priced between $0.25 and $0.50 for bulk orders (MOQ 5–100 pieces) Alibaba Alibaba.

* Retail/Specialist Pricing: In the secondary electronics market, unit prices range from $1.05 to $2.65 depending on the distributor and stock age Digipart Utsource.

* Stock Status: The part is officially Obsolete/End-of-Life (EOL). While "New Original" stock exists in Shenzhen and among global brokers, availability is finite. Buyers are advised to verify Date Codes (DC) to ensure component reliability Ovaga.

Product Specifications & Trends

* Technical Role: It is a bipolar IC designed for AC induction motor control, featuring an internal frequency-to-voltage converter and triac pre-driver.

* Key Features: Integrated soft-start, overload protection (fold-back characteristic), and tachometer monitoring for short/open loops Rxelectronics Ovaga.

* Packaging: Most commonly found in DIP-18 (Through-Hole) for legacy industrial boards and SOP-16 for surface-mount applications.

* Market Insight: Demand is currently driven by MRO (Maintenance, Repair, and Operations) for older industrial HVAC systems, automotive ECUs, and power tools. In new designs, it is increasingly replaced by newer series like the U2010B or digital PWM controllers Censtry Ovaga.
