Description and Introduction

HIGH-VOLTAGE/ HIGH-CURRENT DARLINGTON ARRAYS The ULN2001 is a high-voltage, high-current Darlington transistor array manufactured by STMicroelectronics (STM). Below are the specifications, descriptions, and features based on the factual information available:

### **Specifications:**  
- **Configuration:** Monolithic Darlington transistor array (1 channel).  
- **Output Current (per channel):** 500 mA (max).  
- **Output Voltage (max):** 50 V.  
- **Input Voltage (max):** 30 V.  
- **Input Current (max):** 1.5 mA.  
- **Saturation Voltage (Vce(sat)):** 1.6 V (max) at 350 mA.  
- **Power Dissipation (Pd):** 1 W (per package).  
- **Operating Temperature Range:** -20°C to +85°C.  
- **Package Type:** PDIP-8, SO-8.  

### **Descriptions:**  
- The ULN2001 is a single-channel Darlington transistor array designed for interfacing between low-level logic circuits and high-power loads.  
- It is part of the ULN200x series, which includes multiple configurations (ULN2002, ULN2003, etc.).  
- The device features open-collector outputs with integral clamp diodes for inductive load protection.  
- It is commonly used in relay drivers, motor controllers, LED displays, and other switching applications.  

### **Features:**  
- **High-Voltage and High-Current Capability:** Suitable for driving inductive loads.  
- **Integrated Suppression Diodes:** Protects against back EMF from inductive loads.  
- **TTL/CMOS Compatible Inputs:** Works with 5V logic levels.  
- **Single-Channel Configuration:** Ideal for simple switching applications.  
- **Reliable and Robust Design:** Ensures stable performance in industrial environments.  

For detailed electrical characteristics and application notes, refer to the official STMicroelectronics datasheet.
