Description and Introduction

Dual-Slot Cardbus Power-Interface Switches for Serial PCMCIA Controllers The TPS2226A is a power-distribution switch designed for applications requiring multiple power switches. Below are the factual details about its manufacturer, specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Specifications:**  
- **Input Voltage Range (VIN):** 2.7V to 5.5V  
- **Continuous Current per Channel:** 1.5A (max)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical) at 5V  
- **Number of Channels:** 2  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-Pin SOIC (D)  

### **Descriptions:**  
The TPS2226A is a dual-channel power-distribution switch with integrated protection features. It is designed for hot-swap and power-rail management in portable and embedded systems. Each switch is controlled independently, allowing flexible power sequencing.  

### **Features:**  
- **Integrated FETs:** Low RDS(ON) for efficient power delivery.  
- **Current Limiting:** Protects against excessive load currents.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Fast Short-Circuit Response:** Quickly disables output in fault conditions.  
- **Controlled Slew Rate:** Reduces inrush current during turn-on.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  

This information is sourced from the official Texas Instruments datasheet for the TPS2226A.
