Description and Introduction

?0.75?C Remote and Local Temperature Sensor with SMBus Interface 8-VSSOP 0 to 125 The LM89CIMM/NOPB is a temperature sensor and fan controller manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Supply Voltage Range:** 3.0V to 3.6V  
- **Temperature Measurement Range:** -40°C to +125°C  
- **Accuracy:** ±3°C (max) from +60°C to +100°C  
- **Resolution:** 11-bit ADC for temperature sensing  
- **Interface:** SMBus/I²C compatible  
- **Package:** 10-pin VSSOP (MSOP)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Fan Control:** PWM output with programmable settings  

### **Descriptions:**  
The LM89CIMM/NOPB is a high-accuracy digital temperature sensor with an integrated fan controller. It monitors the temperature of a remote diode (e.g., CPU) and its own internal temperature. It provides programmable fan control via PWM output to optimize cooling performance while minimizing noise.  

### **Features:**  
- Remote diode temperature sensing  
- Internal temperature sensor  
- Programmable fan speed control  
- SMBus/I²C interface with alert function  
- Low power consumption  
- Small form factor (10-pin VSSOP)  
- RoHS compliant  

This device is commonly used in PCs, servers, and other systems requiring thermal management.
