Description and Introduction

Single, Current-Limited, Power-Distribution Switch 5-SOT-23 -40 to 85 The TPS2051BDBVRG4 is a power distribution switch manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A  
- **On-Resistance (RDS(ON)):** 95mΩ (typical) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  
- **Output Discharge:** Active low enable with output discharge  
- **Fault Protection:** Thermal shutdown and overcurrent protection  

### **Descriptions:**
- The TPS2051BDBVRG4 is a single-channel power-distribution switch designed for applications requiring precise current limiting and thermal protection.  
- It integrates a low on-resistance MOSFET with controlled rise and fall times to minimize inrush current.  
- Suitable for USB ports, hot-swap applications, and power management in portable devices.  

### **Features:**
- **Adjustable Current Limit:** Protects downstream circuits from overcurrent conditions.  
- **Fast Overcurrent Response:** Responds quickly to short-circuit events.  
- **Thermal Shutdown:** Prevents damage due to excessive heat.  
- **Low Quiescent Current:** Consumes minimal power when disabled.  
- **Controlled Slew Rate:** Reduces EMI and voltage transients during switching.  
- **Reverse Current Blocking:** Prevents backflow when the switch is off.
