Description and Introduction

POWER SUPPLY SUPERVISORY CIRCUIT The UC3544DW is a high-speed, dual-channel MOSFET driver manufactured by Unitrode (now part of Texas Instruments). Below are the factual specifications, descriptions, and features:  

### **Manufacturer:**  
- **Unitrode (now Texas Instruments)**  

### **Specifications:**  
- **Number of Channels:** 2 (Dual)  
- **Output Current (Peak):** ±4A  
- **Supply Voltage Range:** 4.5V to 18V  
- **Propagation Delay (Typical):** 25ns  
- **Rise/Fall Time (Typical):** 15ns (with 1nF load)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16 (DW)  

### **Descriptions:**  
- The UC3544DW is a high-speed, dual-channel MOSFET driver designed for driving power MOSFETs and IGBTs in switching applications.  
- It features independent inputs and outputs for each channel, allowing flexible control.  
- The device is optimized for fast switching with low propagation delays and high peak output current.  

### **Features:**  
- **High Peak Output Current:** ±4A for fast switching.  
- **Low Propagation Delay:** Ensures minimal switching losses.  
- **Wide Supply Voltage Range:** Supports 4.5V to 18V operation.  
- **Independent Inputs & Outputs:** Allows separate control of each channel.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **TTL/CMOS Compatible Inputs:** Works with standard logic levels.  
- **High Noise Immunity:** Robust performance in noisy environments.  

This information is based solely on the technical specifications and features of the UC3544DW.
