STG3220QTR

Overview

The STG3220QTR is a dual single-pole double-throw (SPDT) analog switch fabricated in silicon gate C2MOS technology. It operates within a supply voltage range of 1.65 V to 4.3 V and features an ultra-low quiescent current of 1 μA maximum at 85 °C. The device provides a typical on-resistance of 4.8 Ω at 4.3 V and supports a -3 dB bandwidth of 800 MHz. It includes integrated fail-safe functionality for over-voltage protection when powered off, dedicated port charging detection with interrupt signaling, and high ESD immunity exceeding 4000 V on data pins.

Feature Summary

Dual SPDT switching architecture with integrated fail-safe function for over-voltage tolerance during power-off states
Dedicated port charging detection circuit that signals the processor via an interrupt pin when USB D+/D- lines are high
High-speed signal switching compliant with USB 2.0 high-speed standards and featuring break-before-make delay
Robust electrostatic discharge protection exceeding JESD22 specifications across all pins

Applications

Mobile phones
USB 2.0 high-speed signal switching
Portable applications requiring low voltage operation

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt as the QFN10 form factor requires careful handling. Ensure storage conditions align with moisture sensitivity level requirements before reflow soldering processes.

Selection Notes

Select this component for designs requiring low voltage operation between 1.65 V and 4.3 V. Consider the 800 MHz bandwidth for high-frequency signal routing. Evaluate the interrupt feature if dedicated port charging detection is required for USB interfaces.

Part Context

The STG3220QTR belongs to the STG3220 family of low voltage high bandwidth switches. It utilizes a QFN10 package measuring 1.8 x 1.4 mm. The 'QTR' suffix indicates tape and reel packaging suitable for automated surface mount assembly.
