Description and Introduction

Pin-Selectable Trip Point 1.4V-Capable Family of Temperature Switches 6-SOT -40 to 125 The TMP302BDRLR is a temperature switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Temperature Threshold Accuracy:** ±1.5°C (max)  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Supply Current:** 4.5µA (typical)  
- **Output Type:** Open-drain  
- **Hysteresis:** 5°C (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-563 (6-pin)  

### **Descriptions:**  
The TMP302BDRLR is an ultra-low-power, high-accuracy temperature switch that monitors system temperatures and provides an open-drain output when the temperature exceeds a factory-programmed threshold. It is designed for applications requiring minimal power consumption and reliable thermal protection.  

### **Features:**  
- **Factory-Programmed Trip Point:** Available in multiple threshold options (e.g., 50°C, 70°C, 90°C).  
- **Low Quiescent Current:** 4.5µA (typical) for battery-powered applications.  
- **Wide Supply Voltage Range:** Supports operation from 1.6V to 5.5V.  
- **Small Form Factor:** SOT-563 package (1.6mm x 1.6mm).  
- **No External Components Required:** Simplifies design integration.  
- **Hysteresis for Stable Switching:** Prevents output oscillation near the threshold.  

This device is commonly used in thermal management for consumer electronics, industrial systems, and battery-powered applications.
