Description and Introduction

HIGH SIDE DRIVER Part L9820 is a monolithic integrated circuit designed for automotive applications, specifically for driving solenoids and relays. Below are the manufacturer specifications, descriptions, and features:  

### **Manufacturer Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Type:** Octal Low-Side Driver  
- **Operating Voltage:** 5V to 28V  
- **Output Current:** Up to 0.5A per channel (8 channels total)  
- **Output Protection:** Overcurrent, thermal shutdown, and inductive load clamping  
- **Logic Inputs:** CMOS/TTL compatible  
- **Package:** PowerSO-36  

### **Description:**  
The L9820 is an 8-channel low-side driver IC intended for automotive solenoid and relay control. It integrates protection features such as overcurrent detection, thermal shutdown, and inductive load clamping, making it suitable for harsh automotive environments.  

### **Features:**  
- Eight independent low-side drivers  
- Output current capability: 0.5A per channel  
- Built-in diagnostics (open-load detection, short-to-ground, and overtemperature)  
- CMOS/TTL compatible inputs  
- Low standby current consumption  
- Protection against reverse battery conditions  
- Designed for automotive applications (AEC-Q100 qualified)  

This information is based on the manufacturer's datasheet and technical documentation.
