Description and Introduction

0.7A, 2.7-5.5V Dual (1In/2Out) Hi-Side MOSFET, Fault Report, Act-Low Enable 8-SOIC -40 to 85 The TPS2042DRG4 is a power distribution switch manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS2042DRG4  
- **Package:** SOIC-8  
- **Type:** Dual-channel power distribution switch  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current per Channel:** 0.5A  
- **On-Resistance (RDS(ON)):** 100mΩ (typical)  
- **Overcurrent Protection Threshold:** 0.75A (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Fault Reporting:** Thermal shutdown and overcurrent flag  

### **Descriptions:**
The TPS2042DRG4 is a dual-channel power distribution switch designed for applications requiring multiple power rails. It provides controlled power switching with overcurrent and thermal protection. Each channel operates independently, making it suitable for USB hubs, portable devices, and other power management applications.

### **Features:**
- **Dual Independent Channels:** Allows control of two separate power rails.  
- **Low On-Resistance:** Minimizes voltage drop and power loss.  
- **Overcurrent Protection:** Limits current to prevent damage.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Fault Reporting:** Provides status flags for overcurrent and thermal events.  
- **Controlled Rise Time:** Reduces inrush current during turn-on.  
- **Wide Input Voltage Range:** Supports 2.7V to 5.5V operation.  
- **Small Footprint:** SOIC-8 package for space-constrained designs.  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

0.7A, 2.7-5.5V Dual (1In/2Out) Hi-Side MOSFET, Fault Report, Act-Low Enable 8-SOIC -40 to 85

Alternative Part Number

  • MIC2026-2YM --: Dual-channel high-side power switch with current limiting, functionally similar to the TPS2042 dual-channel switch and available in an SOIC package.
  • AP2151SG-13 --: Single-channel current-limited high-side power switch with enable and fault flag, suitable as a functional replacement where channel count is not critical.
  • LM3526MX-L --: Dual-port USB power switch with overcurrent protection from the same vendor, offering similar current-limit and fault-reporting behavior.
