Description and Introduction

SOT-23, ±3°C Accurate, Factory Preset Thermostat The LM26CIM5-SHA is a precision temperature switch manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Precision Temperature Switch  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Temperature Threshold Accuracy:** ±0.5°C (typical)  
- **Hysteresis:** Programmable (factory-set or adjustable)  
- **Output Type:** Open-drain or push-pull (depending on variant)  
- **Package:** SOT-23-5  
- **Operating Temperature Range:** -40°C to +125°C  
- **Quiescent Current:** Low (typically in µA range)  

### **Descriptions:**  
The LM26CIM5-SHA is a high-accuracy, low-power temperature switch designed for system monitoring and thermal protection. It provides a digital output that toggles when the sensed temperature crosses a predefined threshold. The device is factory-programmed for specific trip points but may support user-adjustable settings in some variants.  

### **Features:**  
- **Precision Temperature Sensing:** ±0.5°C accuracy ensures reliable thermal monitoring.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Wide Supply Range:** Operates from 2.7V to 5.5V.  
- **Small Form Factor:** SOT-23-5 package saves board space.  
- **Programmable Hysteresis:** Prevents output oscillation near the threshold.  
- **Open-Drain Output:** Allows flexible interfacing with other logic levels.  
- **Robust Performance:** Operates across industrial temperature ranges (-40°C to +125°C).  

This information is strictly based on available data for the LM26CIM5-SHA from NSC. For exact application details, refer to the official datasheet.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • MAX6501UKP105+T --: Pin-compatible SOT-23 temperature switch with factory-set trip point, functionally similar to the LM26 thermostat family and available from a different vendor.
  • TC6501P105VCTTR --: SOT-23 temperature switch with preset threshold and open-drain output, a direct functional substitute for LM26CIM5-SHA in thermal shutdown circuits.
  • ADT6501SRJZP105RL7 --: SOT-23 temperature switch with fixed setpoint and active-low output, offering comparable accuracy and a different series name for easy distinction.
  • MAX6501UKP095 --: Pin-compatible SOT-23 temperature switch with similar trip-point and open-drain output, widely used as a direct substitute for LM26 thermostat functions.
  • ADT6501SRJZP095RL7 --: SOT-23 temperature switch offering comparable threshold accuracy and active-low output, suitable drop-in replacement in thermal protection circuits.
  • TC6501P095VCTTR --: Low-power SOT-23 temperature switch with similar trip point and logic output, an economical alternative for LM26-based designs.
