Description and Introduction

Digital Temperature Sensors and Thermal Watchdog with Bus Lockup Protection The MAX7500MSA is a temperature sensor and fan-speed controller manufactured by Maxim Integrated. Here are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7500MSA  
- **Type:** Temperature Sensor with Fan-Speed Control  
- **Interface:** I²C/SMBus-Compatible  
- **Supply Voltage Range:** 3.0V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Accuracy:** ±1°C (from +60°C to +100°C)  
- **Resolution:** 9 to 12 bits (programmable)  
- **Fan Control:** PWM output for fan-speed regulation  
- **Package:** 8-pin SOIC  

### **Descriptions:**
The MAX7500MSA integrates a temperature sensor and fan-speed controller in a single chip. It communicates via an I²C/SMBus interface, allowing for digital temperature readings and programmable fan control. The device is designed for thermal management in systems requiring precise temperature monitoring and cooling adjustments.

### **Features:**
- **Digital Temperature Sensing:** Provides accurate temperature readings with programmable resolution.  
- **Programmable Fan Control:** Adjusts fan speed via PWM output based on temperature thresholds.  
- **Low Operating Voltage:** Works from 3.0V to 5.5V, suitable for low-power applications.  
- **Wide Temperature Range:** Operates from -55°C to +125°C.  
- **I²C/SMBus Interface:** Allows easy integration with microcontrollers and system management controllers.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Digital Temperature Sensors and Thermal Watchdog with Bus Lockup Protection

Alternative Part Number

  • LM75BIMM-3 --: Pin-compatible I2C temperature sensor with similar accuracy and supply range, widely available and often cheaper.
  • TMP102AIDRLR --: I2C digital temperature sensor with comparable resolution and accuracy, small SOT-23 package, good drop-in functional replacement.
  • STLM75M2F --: I2C temperature sensor with similar specifications and pinout, suitable alternative when MAX7500 is unavailable.
