Description and Introduction

Low-Cost, 2.7V to 5.5V, Micropower Temperature Switches in SOT23 and TO-220 The MAX6502UKP045 is a temperature switch manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **MAXIM** (now part of Analog Devices)  

### **Part Number:**  
- **MAX6502UKP045**  

### **Description:**  
The MAX6502UKP045 is a precision, low-power temperature switch that monitors temperature and provides a digital output when the temperature exceeds a predefined threshold. It is designed for applications requiring thermal management, such as in consumer electronics, industrial systems, and automotive environments.  

### **Key Features:**  
1. **Temperature Threshold:**  
   - Factory-set trip temperature: **+45°C**  

2. **Accuracy:**  
   - **±0.5°C** (typical) near the trip point  

3. **Output Type:**  
   - Open-drain active-low output  

4. **Supply Voltage Range:**  
   - **2.7V to 5.5V**  

5. **Low Power Consumption:**  
   - **30µA** (typical) supply current  

6. **Hysteresis:**  
   - **5°C** (prevents output oscillation near the threshold)  

7. **Package:**  
   - **SOT23-5** (small form factor)  

8. **Operating Temperature Range:**  
   - **-40°C to +125°C**  

9. **Applications:**  
   - Overheating protection  
   - Thermal shutdown circuits  
   - System monitoring  

### **Additional Notes:**  
- The trip temperature is factory-programmed and not user-adjustable.  
- The open-drain output requires a pull-up resistor for proper operation.  

This information is based on the manufacturer's datasheet and technical specifications. For detailed electrical characteristics and application circuits, refer to the official documentation.

Application Scenarios & Design Considerations

Low-Cost, 2.7V to 5.5V, Micropower Temperature Switches in SOT23 and TO-220

Alternative Part Number

  • LM26CIM5-TPA --: Pin-compatible SOT-23 temperature switch with factory-set trip point, similar open-drain output and supply range, widely available alternative to the MAX6502 family.
  • ADT6501ARJZ-R2 --: SOT-23 temperature switch with programmable trip point and active-low output, functionally similar to MAX6502 and suitable as a drop-in replacement in most thermal monitoring designs.
  • STLM20W87F --: Low-power analog temperature sensor in SOT-23 package with comparable accuracy and supply voltage, usable where the MAX6502 threshold switch function can be implemented with external comparator.
