- **Operating Voltage:** 3.5V to 24V  
- **Output Type:** Open Drain  
- **Operating Temperature Range:** -40°C to +150°C  
- **Magnetic Sensitivity:** Typically 35 Gauss (Bop) and 25 Gauss (Brp)  
- **Switching Frequency:** Up to 100 kHz  
- **Package Options:** SOT-23, TO-92UA  

### **Descriptions:**  
- The **US1881** is a unipolar Hall-effect switch designed for digital applications.  
- It activates in the presence of a South pole magnetic field and deactivates when the field is removed.  
- Suitable for position sensing, speed detection, and proximity switching in automotive, industrial, and consumer applications.  

### **Features:**  
- **High Sensitivity:** Low magnetic switch points (Bop/Brp).  
- **Wide Voltage Range:** Operates from 3.5V to 24V.  
- **Robust Design:** High-temperature tolerance and reverse polarity protection.  
- **Open-Drain Output:** Allows easy interfacing with microcontrollers and logic circuits.  
- **AEC-Q100 Qualified:** Suitable for automotive applications.  

This sensor is commonly used in brushless DC motor control, gear tooth sensing, and flow meters.
