Description and Introduction

Remote and Local Temperature Sensor with N-Factor and Series-R Correction in WCSP 8-SOT-23 -40 to 125 The TMP421AIDCNT is a temperature sensor manufactured by Texas Instruments. Below are the factual details from Ic-phoenix technical data files:  

### **Manufacturer:**  
Texas Instruments (TI)  

### **IR Specifications:**  
- **Accuracy:** ±1°C (typical) from -40°C to +125°C  
- **Remote Diode Sensor Accuracy:** ±1°C (typical) for +60°C to +100°C  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Resolution:** 0.0625°C  
- **Interface:** I²C/SMBus compatible  

### **Descriptions:**  
The TMP421AIDCNT is a high-precision, low-power digital temperature sensor with a built-in local temperature sensor and remote diode temperature sensing capability. It is designed for monitoring processor temperatures and other thermal management applications.  

### **Features:**  
- **Local and Remote Temperature Sensing:** Measures its own temperature and an external diode-connected transistor (e.g., CPU diode).  
- **Programmable Alert Function:** Supports overtemperature and undertemperature alerts.  
- **Low Power Consumption:** Typically 45µA (active mode).  
- **Small Package:** 6-pin SOT-23 (DCN) package.  
- **Series Resistance Cancellation:** Compensates for PCB trace resistance in remote sensing.  
- **Beta Compensation:** Corrects errors due to process variations in remote transistors.  

This information is strictly based on the manufacturer's specifications.
