Description and Introduction

1A Single-Slot CardBay PC Card Power Switch w/Parallel Interface 14-HTSSOP -40 to 85 The TPS2221PWPR is a power-distribution switch manufactured by Texas Instruments (TI). Here 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:** 1.5A (typical)  
- **On-Resistance (RDS(ON)):** 70mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** HTSSOP-20 (PowerPAD™)  
- **Fault Protection:** Overcurrent, thermal shutdown, reverse current blocking  
- **Control Interface:** Logic-level enable input  
- **Quiescent Current:** 1µA (typical in shutdown mode)  

### **Descriptions:**  
The TPS2221PWPR is a single-channel, load-switch IC designed for power distribution in portable and battery-powered applications. It provides controlled power switching with protection features to ensure safe operation.  

### **Features:**  
- **Integrated Power MOSFET:** Low RDS(ON) for minimal voltage drop.  
- **Adjustable Current Limit:** Protects against excessive load currents.  
- **Fast Turn-Off:** Prevents reverse current flow when disabled.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Small Footprint:** HTSSOP-20 package with PowerPAD™ for improved thermal performance.  
- **Low Standby Current:** Ideal for battery-powered applications.  

This information is strictly factual from the TI datasheet for the TPS2221PWPR.
