Description and Introduction

Resistor-Programmable SOT Temperature Switches The MAX6509CAUK+T is a temperature sensor and voltage monitor manufactured by Maxim Integrated (now part of Analog Devices). Here are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX6509CAUK+T  
- **Type:** Temperature Sensor with Voltage Monitor  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** **0°C to +70°C** (Commercial grade)  
- **Supply Voltage Range:** **2.7V to 5.5V**  
- **Accuracy:** **±1.5°C** (from +60°C to +100°C)  
- **Output Type:** Open-Drain Active-Low Alarm  
- **Threshold Options:** Factory-programmed (multiple variants available)  
- **Quiescent Current:** **30µA** (typical)  

### **Descriptions:**  
The MAX6509CAUK+T is a low-power, precision temperature sensor with an integrated voltage monitor. It provides an open-drain output that asserts low when the temperature exceeds a factory-set threshold. It is designed for applications requiring temperature monitoring and system protection, such as in consumer electronics, industrial systems, and computing devices.  

### **Features:**  
- **Integrated Temperature Sensor and Voltage Monitor**  
- **Factory-Programmed Temperature Threshold** (specific to variant)  
- **Open-Drain Active-Low Alarm Output**  
- **Low Power Consumption (30µA typical)**  
- **Wide Supply Voltage Range (2.7V to 5.5V)**  
- **Small SOT-23-5 Package**  
- **No External Components Required**  
- **Suitable for Over-Temperature Protection**  

For exact threshold values and variant-specific details, refer to the official datasheet from Analog Devices (formerly Maxim Integrated).

Application Scenarios & Design Considerations

Resistor-Programmable SOT Temperature Switches

Alternative Part Number

  • LM57CISD-10/NOPB --: Pin-compatible temperature switch with analog and comparator outputs in SOT-23-5, similar function to the MAX6509.
  • ADT6501ARJZ-R2 --: Low-cost temperature switch with programmable trip point in SOT-23-5, a direct functional alternative.
  • TC6501P065VCTTR --: Temperature switch with open-drain output in SOT-23-5, suitable replacement for the MAX6509 in thermal monitoring.
  • LTC1840CMS8#PBF --: Pin-compatible temperature switch/comparator in SOT-23/MSOP family with similar open-drain output and threshold behavior, widely available and functionally close.
  • LM26CIM5-TPA --: Integrated temperature switch with factory-set trip point and open-drain output, suitable drop-in for many MAX6509 applications with comparable supply range.
