Description and Introduction

PowerPath Controller for Dual Battery Systems The LTC1479IG is a dual N-channel power MOSFET driver manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 15V  
- **Output Current (Peak):** 1A  
- **Propagation Delay:** 30ns (typical)  
- **Rise/Fall Time:** 15ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP  

### **Descriptions and Features:**  
- Designed for driving N-channel power MOSFETs in synchronous rectification applications.  
- Includes two independent drivers with separate inputs and outputs.  
- Low propagation delay ensures high-speed switching.  
- Under-voltage lockout (UVLO) protection prevents operation below 4V.  
- Logic-compatible inputs (TTL/CMOS).  
- Low quiescent current in shutdown mode.  
- Suitable for DC/DC converters, motor control, and power management systems.  

The LTC1479IG is optimized for efficiency and reliability in high-frequency switching applications.
