Description and Introduction

Precision Adjustable Current-Limited Power-Distribution Switches 8-SON -40 to 85 The TPS2556DRBR is a power-distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS2556DRBR  

### **Description:**  
The TPS2556DRBR is an adjustable current-limited power-distribution switch designed for applications requiring precise current limiting and protection. It is used in USB ports, hot-swap circuits, and other power-management systems.  

### **Key Features:**  
- **Adjustable Current Limit:** Ranges from 50mA to 1.5A (set via an external resistor).  
- **Low On-Resistance:** 70mΩ (typical) to minimize voltage drop.  
- **Wide Input Voltage Range:** 2.5V to 6.5V.  
- **Reverse Current Blocking:** Prevents backflow when the output voltage exceeds the input.  
- **Overcurrent Protection:** Fast response to short-circuit conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Fast Turn-On:** Controlled rise time to reduce inrush current.  
- **Small Package:** 8-pin SON (DRB) package for space-constrained designs.  

### **Applications:**  
- USB power management  
- Hot-swapable power supplies  
- Portable devices  
- Industrial and automotive systems
