Description and Introduction

Single Universal Serial Bus Port Transient Suppressor The SN65220DBVT is a USB port power switch and overvoltage protection device manufactured by Texas Instruments (TI).  

**Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Load Current:** 500mA  
- **Overvoltage Protection Threshold:** Adjustable (default: 6.1V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

**Descriptions:**  
The SN65220DBVT is designed to protect USB ports from overvoltage conditions while providing controlled power switching. It integrates a low-resistance P-channel MOSFET for power distribution and includes an adjustable overvoltage lockout feature.  

**Features:**  
- Adjustable overvoltage lockout (OVLO)  
- Reverse current blocking  
- Low quiescent current (20µA typical)  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO)  
- Short-circuit protection  

This device is commonly used in USB hubs, docking stations, and other portable electronics requiring power management and protection.

Application Scenarios & Design Considerations

Single Universal Serial Bus Port Transient Suppressor

Alternative Part Number

  • USBLC6-2SC6 --: Dual-line USB ESD protection device in SOT-23-6, functionally similar to the SN65220 dual ESD protection array and widely available as a drop-in style alternative.
  • TPD2E001DRLR --: Two-channel ESD protection diode array from TI with comparable clamping performance, same vendor family support, and a different series naming for easy distinction.
  • SRV05-4.TCT --: Multi-line ESD/transient protection array suitable for USB and data-line clamping, offering similar protection levels in a small package as a cross-vendor alternative.
