Description and Introduction

5.5V, 0.2A, 500m?, 100mA Current Limit Active-Low Load Switch 5-SC70 -40 to 85 The TPS22942DCKR is a load switch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range (VIN):** 1.2V to 5.5V  
- **Continuous Current Rating:** 2A  
- **On-Resistance (RON):** 35mΩ (typical at 5V VIN)  
- **Quiescent Current (IQ):** 0.5µA (typical)  
- **Shutdown Current (ISD):** 0.1µA (typical)  
- **Control Logic:** Active-high enable (ON pin)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SC-70 (DCK), 5-pin  

### **Descriptions:**  
- The TPS22942DCKR is a small, ultra-low leakage load switch designed for power distribution in portable and battery-powered applications.  
- It integrates a low RON N-channel MOSFET for efficient power switching.  
- Features controlled turn-on to reduce inrush current.  

### **Features:**  
- **Low On-Resistance:** Minimizes voltage drop and power loss.  
- **Ultra-Low Quiescent Current:** Extends battery life in portable devices.  
- **Fast Turn-On:** Adjustable slew rate for controlled power-up.  
- **Reverse Current Blocking:** Prevents current flow from output to input when disabled.  
- **Small Package:** SC-70 (5-pin) for space-constrained designs.
