Description and Introduction

0.345A, 2.7-5.5V Quad (2In/ 4Out) Hi-Side MOSFET, Fault Report, Act-Low Enable The TPS2048AD is a power distribution switch manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** SOIC-8  
- **Number of Channels:** 1  
- **Fault Protection:** Overcurrent, Thermal Shutdown  
- **Turn-On Time:** 1ms (typical)  
- **Turn-Off Time:** 1ms (typical)  

### **Description:**  
The TPS2048AD is a single-channel power-distribution switch designed for applications requiring precise current limiting and protection. It integrates a low on-resistance N-channel MOSFET and control circuitry to manage power distribution in USB and other low-voltage systems.  

### **Features:**  
- **Adjustable Current Limit:** Protects downstream circuits from overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Fast Turn-On/Turn-Off:** Ensures quick response in power switching.  
- **Low Standby Current:** Reduces power consumption when disabled.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  

This information is based solely on TI's official documentation for the TPS2048AD.

Application Scenarios & Design Considerations

0.345A, 2.7-5.5V Quad (2In/ 4Out) Hi-Side MOSFET, Fault Report, Act-Low Enable

Alternative Part Number

  • MIC2026-1YM --: Dual-channel high-side power switch with current limiting and thermal shutdown, functionally similar to the TPS2048A family and available in a comparable SOIC package.
  • AP2553W6-7 --: Single-channel current-limited high-side power switch with adjustable current limit and thermal protection, suitable as a drop-in functional replacement in many USB power-switch designs.
  • LM3526MX-L --: Dual-port USB power switch with overcurrent protection from the same vendor, offering similar enable and fault-reporting behavior for USB power distribution applications.
