Description and Introduction

Dual, Current-Limited, Power-Distribution Switches The TPS2042BDR is a power distribution switch manufactured by Texas Instruments (TI) and Burr-Brown (BB). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Burr-Brown (BB)  
- **Part Number:** TPS2042BDR  
- **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:** Adjustable (default ~1.5A)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Fault Reporting:** Thermal shutdown and overcurrent flag  

### **Descriptions:**  
The TPS2042BDR is a dual-channel power switch designed for applications requiring controlled power distribution. It provides protection against overcurrent and thermal overload while minimizing voltage drops due to low on-resistance. The device is commonly used in USB hubs, hot-swap circuits, and other power management systems.  

### **Features:**  
- **Dual Independent Power Switches** – Allows control of two separate loads.  
- **Low On-Resistance (100mΩ typical)** – Reduces power loss.  
- **Adjustable Current Limit** – Protects downstream circuits.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Fast Overcurrent Response** – Quickly disconnects faulty loads.  
- **Undervoltage Lockout (UVLO)** – Ensures proper operation within voltage range.  
- **Logic-Level Enable Inputs** – Compatible with 3.3V/5V logic.  

This information is strictly based on manufacturer-provided data.
