Description and Introduction

3.3V LDO + Dual Switch For USB Peripherals, Active-Low Enables 8-MSOP-PowerPAD -40 to 85 The TPS2148IDGNG4 is a power-distribution switch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS2148IDGNG4  
- **Type:** Power Distribution Switch  
- **Output Configuration:** High Side  
- **Operating Voltage:** 2.7V to 5.5V  
- **Continuous Current:** 1.5A  
- **On-Resistance (RDS(ON)):** 80mΩ (typical)  
- **Quiescent Current:** 35µA (typical)  
- **Shutdown Current:** 1µA (typical)  
- **Overcurrent Protection:** Adjustable (1A to 2A)  
- **Fault Protection:** Thermal Shutdown, Reverse Current Blocking  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin HVSSOP (DGNG)  

### **Descriptions:**
The TPS2148IDGNG4 is a single-channel, load switch designed for power distribution in portable and battery-powered applications. It provides controlled power switching with adjustable current limiting, thermal shutdown, and reverse current blocking to protect downstream circuits.  

### **Features:**
- **Adjustable Current Limit:** Programmable from 1A to 2A via an external resistor.  
- **Fast Overcurrent Response:** Limits inrush current during startup.  
- **Low On-Resistance:** 80mΩ (typical) minimizes voltage drop.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Reverse Current Blocking:** Prevents backflow when disabled.  
- **Controlled Turn-On:** Reduces inrush current with slew-rate control.  
- **Low Quiescent Current:** 35µA (typical) for power efficiency.  
- **Small Package:** 8-pin HVSSOP (DGNG) for space-constrained designs.
