Description and Introduction

Precision Adjustable Current-Limited Power-Distribution Switches 8-SON -40 to 85 The TPS2557DRBR is a power-distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

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

### **Part Number:**  
TPS2557DRBR  

### **Description:**  
The TPS2557DRBR is an adjustable current-limited power-distribution switch designed for applications requiring precise current limiting, such as USB ports, hubs, and other power-management systems. It provides protection against overcurrent and thermal shutdown conditions.

### **Key Features:**  
1. **Adjustable Current Limit:**  
   - Programmable current limit from **75mA to 1.7A** via an external resistor.  

2. **Low On-Resistance:**  
   - **36mΩ (typical)** RDS(ON) for minimal voltage drop.  

3. **Wide Input Voltage Range:**  
   - Operates from **2.5V to 6.5V**.  

4. **Fast Overcurrent Response:**  
   - Responds quickly (µs range) to short-circuit conditions.  

5. **Reverse Current Blocking:**  
   - Prevents reverse current flow when disabled.  

6. **Thermal Shutdown Protection:**  
   - Automatically disables the switch if excessive temperature is detected.  

7. **Controlled Rise Time:**  
   - Reduces inrush current during turn-on.  

8. **Small Package:**  
   - **8-pin SON (DRB) package** for space-constrained designs.  

9. **Enable Pin (Active High):**  
   - Allows external control of the switch.  

10. **Fault Indication:**  
   - Open-drain **FAULT** pin signals overcurrent or thermal shutdown conditions.  

### **Applications:**  
- USB ports (host/peripheral)  
- Power distribution in portable devices  
- Hot-swap and power-rail protection  
- Hubs and docking stations  

This information is based solely on TI's datasheet for the TPS2557DRBR.
