Partnumber Manufacturer Quantity Availability
UDN2987 30 In Stock

Description and Introduction

8-CHANNEL SOURCE DRIVER WITH OVER-CURRENT PROTECTION The UDN2987 is a high-current, high-voltage peripheral driver designed for use in applications requiring up to 500 mA of load current. It is manufactured by Allegro MicroSystems.  

### **Specifications:**  
- **Output Current:** Up to 500 mA per channel  
- **Output Voltage:** 50 V (max)  
- **Number of Channels:** 8 (octal)  
- **Input Compatibility:** TTL, CMOS, and PMOS logic levels  
- **Supply Voltage (VDD):** 4.5 V to 36 V  
- **Power Dissipation:** Internally limited  
- **Package Type:** 18-pin DIP (Dual In-line Package) or SOIC (Surface Mount)  

### **Descriptions and Features:**  
- **High-Voltage Outputs:** Capable of driving inductive loads such as relays, solenoids, and lamps.  
- **Built-in Clamp Diodes:** Includes integrated flyback diodes for inductive load protection.  
- **Thermal Shutdown:** Features internal thermal protection to prevent damage from overheating.  
- **Logic-Level Inputs:** Compatible with a wide range of control signals (TTL, CMOS).  
- **Open-Collector Outputs:** Allows flexible interfacing with different load types.  
- **Sink or Source Operation:** Can be configured to sink or source current depending on application needs.  

This driver is commonly used in industrial control systems, automotive applications, and general-purpose switching circuits.
