Description and Introduction

0.3A, 2.7 to 5.5V Dual (2 Input/ 2 Output) High-Side MOSFET Switch IC, Fault Reporting, 2 Act-Hi En The TPS2090DR is a power distribution switch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 1A (typical)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8 (DR)  
- **Fault Protection:** Overcurrent, thermal shutdown  
- **Enable Logic:** Active-high (EN pin)  
- **Quiescent Current:** 1µA (typical when disabled)  

### **Descriptions:**  
The TPS2090DR is a single-channel power-distribution switch designed for applications requiring controlled power delivery. It provides protection against overcurrent and thermal overload conditions. The device features low on-resistance and fast turn-on response, making it suitable for USB ports, hot-swap applications, and power management in portable electronics.  

### **Features:**  
- Adjustable current limit (1A typical)  
- Fast overcurrent response (<5µs)  
- Thermal shutdown protection  
- Reverse current blocking  
- Low standby current (1µA typical)  
- Under-voltage lockout (UVLO) protection  
- Active-high enable control  

This information is strictly factual and sourced from TI's official documentation.

Application Scenarios & Design Considerations

0.3A, 2.7 to 5.5V Dual (2 Input/ 2 Output) High-Side MOSFET Switch IC, Fault Reporting, 2 Act-Hi En

Alternative Part Number

  • MIC2026-1YM --: Dual high-side power switch with current limiting and thermal shutdown, functionally similar to the TPS2090 dual-channel switch and available in SOIC-8.
  • LM3526MX-L --: Dual-channel USB power switch with overcurrent protection and enable control, a close functional match in the same vendor family but a different series.
  • AP2191SG-13 --: Single-channel current-limited power switch with thermal protection; usable where channel count is flexible and offers a lower-cost alternative.
