Description and Introduction

Current-Limited, Power-Distribution Switches 16-SOIC -40 to 85 The TPS2043BDRG4 is a power distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.7V to 5.5V  
- **Continuous Current Limit:** 0.5A (typical)  
- **On-Resistance (RDS(ON)):** 80mΩ (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  
- **Fault Protection:** Overcurrent, thermal shutdown, and reverse current blocking  

### **Descriptions:**
- The TPS2043BDRG4 is a single-channel, current-limited power distribution switch designed for applications requiring controlled power management.  
- It provides protection for systems against excessive current loads and short circuits.  
- The device features a controlled rise time to minimize inrush current during turn-on.  

### **Features:**
- **Adjustable Current Limit:** Ensures safe operation under fault conditions.  
- **Fast Overcurrent Response:** Quickly shuts down during fault events.  
- **Low Standby Current:** Minimizes power consumption when disabled.  
- **Thermal Shutdown Protection:** Prevents damage due to overheating.  
- **Reverse Current Blocking:** Protects the input supply from reverse current flow.  
- **Enable Pin (Active High):** Allows external control of the switch.  

This information is sourced directly from TI's datasheet for the TPS2043BDRG4.

Application Scenarios & Design Considerations

Current-Limited, Power-Distribution Switches 16-SOIC -40 to 85

Alternative Part Number

  • MIC2505-2YM --: Single high-side power switch with current limiting and thermal shutdown, functionally similar to the TPS2043B family for USB power distribution.
  • AP2191SG-13 --: Current-limited high-side power switch in SO-8, comparable voltage/current ratings and enable control, suitable drop-in for many TPS2043B applications.
  • LM3525MX-L --: TI single-channel USB power switch with current limit and fault reporting, similar topology and pin function though from a different TI series.
