Description and Introduction

SOT-23, ±3°C Accurate, Factory Preset Thermostat The LM26CIM5-XPA is a precision temperature switch manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Temperature Threshold Accuracy:** ±0.5°C (typical)  
- **Hysteresis:** 5°C (typical)  
- **Output Type:** Open-drain  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The LM26CIM5-XPA is a highly accurate temperature switch designed for system monitoring and protection.  
- It features a factory-programmed temperature threshold with a built-in hysteresis to prevent output oscillation near the trip point.  
- The open-drain output can be pulled up to a voltage higher than VDD (up to 5.5V).  

### **Features:**  
- Precision temperature sensing (±0.5°C typical accuracy)  
- Low supply current (10µA typical)  
- Wide operating voltage range (2.7V to 5.5V)  
- Open-drain output for flexible interfacing  
- Small SOT-23-5 package for space-constrained applications  
- Factory-programmed temperature threshold  

This device is commonly used in power management, thermal protection, and system monitoring applications.

Application Scenarios & Design Considerations

SOT-23, ±3°C Accurate, Factory Preset Thermostat

Alternative Part Number

  • MAX6501UKP105+T --: Pin-compatible temperature switch with similar SOT23-5 package and active-low open-drain output, functionally equivalent to the LM26 thermostat function.
  • ADT6501ARJZ-R2 --: SOT23-5 temperature switch with comparable trip point and open-drain output, suitable drop-in replacement for thermal monitoring applications.
  • TC6501P105VCTTR --: Low-power SOT23-5 temperature switch offering similar threshold and output behavior, a viable alternative when the original is unavailable.
