Description and Introduction

CompactPCI Hot Swap Power Manager Industrial Temp IC that meets the PICMG Standard The TPS2345PW is a power distribution switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current per Channel:** 500mA  
- **Number of Channels:** 4  
- **On-Resistance (RDS(ON)):** 80mΩ (typical)  
- **Overcurrent Protection:** Adjustable (50mA to 500mA per channel)  
- **Thermal Shutdown Protection:** Yes  
- **Undervoltage Lockout (UVLO):** Yes  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin TSSOP (PW)  

### **Descriptions:**  
The TPS2345PW is a quad-channel power-distribution switch designed for applications requiring multiple power rails with individual control and protection. It integrates low on-resistance MOSFETs and provides adjustable current limiting, thermal shutdown, and undervoltage lockout for robust system protection.  

### **Features:**  
- **Adjustable Current Limit:** Configurable per channel (50mA to 500mA).  
- **Fast Overcurrent Response:** Protects downstream circuits.  
- **Low Standby Current:** Reduces power consumption.  
- **Independent Enable Control:** Each channel can be individually enabled/disabled.  
- **Fault Reporting:** Open-drain fault output for system monitoring.  
- **Soft-Start Control:** Reduces inrush current during turn-on.  

This device is commonly used in USB hubs, portable devices, and other power-management applications.
