Description and Introduction

20V, 5A, 33m? eFuse with PG 8-SO PowerPAD -40 to 125 The TPS2421-1DDA is a hot swap controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS2421-1DDA  
- **Package:** 8-Pin SOIC (DDA)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range:** 2.9V to 18V  
- **Current Limit Range:** Adjustable  
- **Fault Response:** Circuit breaker with auto-retry or latch-off options  
- **Power Good Output:** Yes  
- **On-Resistance (RDS(ON)):** Low (typically 50mΩ)  

### **Descriptions:**  
The TPS2421-1DDA is a hot swap controller designed to safely manage the insertion and removal of circuit boards in live backplanes. It provides inrush current control, overcurrent protection, and undervoltage lockout (UVLO) to prevent damage to sensitive components.  

### **Features:**  
- **Inrush Current Control:** Limits surge current during power-up.  
- **Adjustable Current Limit:** Allows customization for different load requirements.  
- **Programmable Fault Response:** Supports auto-retry or latch-off modes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Power Good Indicator:** Signals when output voltage is stable.  
- **Low On-Resistance MOSFET:** Minimizes power loss.  
- **Wide Operating Voltage Range:** Supports 2.9V to 18V applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.
