Description and Introduction

Dual In/Single Out Autoswitching Power MUX, Auto Sw, Adj. Cur Limit, Adj. Vol Threshold, Sw Status 8-TSSOP -40 to 85 The TPS2112PWRG4 is a power multiplexer manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Power Management IC (PMIC) - Power Multiplexers  
- **Package:** TSSOP-8 (PWR)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range (VIN1, VIN2):** 2.7V to 5.5V  
- **Output Current:** Up to 1.5A  
- **On-Resistance (RDS(ON)):** 70mΩ (typical)  
- **Switching Type:** Automatic or Manual (controlled via SEL pin)  
- **Quiescent Current:** 1µA (typical) in standby mode  
- **Features:** Overcurrent protection, reverse current blocking  

### **Descriptions:**
The TPS2112PWRG4 is a dual-input, single-output power multiplexer designed for seamless power source switching between two power supplies. It is commonly used in battery-powered applications, portable devices, and systems requiring redundancy or backup power. The device supports automatic or manual switching based on the SEL pin configuration.

### **Features:**
1. **Dual-Input Power MUX:** Allows selection between two power sources (VIN1 and VIN2).  
2. **Low On-Resistance:** 70mΩ (typical) minimizes power loss.  
3. **Wide Input Voltage Range:** 2.7V to 5.5V for compatibility with various power sources.  
4. **Automatic or Manual Switching:** Controlled via the SEL pin.  
5. **Low Quiescent Current:** 1µA (typical) in standby mode for power efficiency.  
6. **Overcurrent Protection:** Safeguards against excessive current draw.  
7. **Reverse Current Blocking:** Prevents backflow between inputs.  
8. **Small Form Factor:** TSSOP-8 package for space-constrained applications.  

This information is strictly based on the manufacturer's datasheet and knowledge base.
