Description and Introduction

Low-cost, +2.7V to +5.5V micropower temperature switch. Output stage open-drain. Standard temperature threshold(C) +105. The MAX6501UKP105-T is a temperature switch manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX6501UKP105-T  
- **Type:** Temperature Switch  
- **Temperature Threshold:** +105°C (factory-set)  
- **Accuracy:** ±4.5°C (over full temperature range)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 30µA (typical)  
- **Output Type:** Open-Drain  
- **Hysteresis:** 10°C (fixed)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT23-5  

### **Descriptions:**
The MAX6501UKP105-T is a low-power, precision temperature switch designed to monitor system temperatures and trigger an alert when the temperature exceeds a preset threshold (+105°C). It features an open-drain output that activates when the temperature rises above the threshold and deactivates when it falls below the threshold minus hysteresis (10°C).  

### **Features:**
- **Factory-Programmed Threshold:** No external components required.  
- **Low Power Consumption:** 30µA typical supply current.  
- **Wide Supply Voltage Range:** Operates from 2.7V to 5.5V.  
- **Small Form Factor:** Available in a compact SOT23-5 package.  
- **Open-Drain Output:** Allows flexible interfacing with logic circuits.  
- **No External Components Needed:** Simplifies design and reduces BOM.  
- **Fixed Hysteresis:** Prevents output oscillation near the threshold.  

This device is commonly used in over-temperature protection for electronics, thermal management, and industrial applications.  

(Note: Always refer to the latest datasheet for updated specifications.)

Application Scenarios & Design Considerations

Low-cost, +2.7V to +5.5V micropower temperature switch. Output stage open-drain. Standard temperature threshold(C) +105.

Alternative Part Number

  • LM57CISD-10/NOPB --: Pin-compatible temperature switch with programmable trip point and analog output, similar SOT-23-5 footprint and function to the MAX6501.
  • ADT6501SRJZ-10RL7 --: Direct functional equivalent temperature switch with factory-set trip point in a small SOT-23 package, suitable drop-in replacement.
  • TC6501P105VCTTR --: Low-power temperature switch with comparable trip point and SOT-23-5 package, offering similar threshold accuracy and open-drain output.
  • ADT6501ARJZ-R2 --: Low-cost temperature switch with factory-set trip point in SOT-23-5, comparable supply range and logic output, good drop-in alternative.
