Description and Introduction

Low Power, Dual Output, Current Mode PWM Controller The UCC2806 is a high-speed, dual-channel MOSFET driver manufactured by Texas Instruments (formerly Unitrode). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VDD):** 10V to 20V  
- **Output Current (Peak):** ±2A  
- **Propagation Delay (Typical):** 30ns  
- **Rise/Fall Time (Typical):** 20ns  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Options:** 8-Pin PDIP, SOIC  

### **Descriptions:**
- The UCC2806 is a dual MOSFET driver designed for high-speed switching applications.  
- It provides independent high-current drive for two N-channel MOSFETs.  
- The device is optimized for use in push-pull, half-bridge, and full-bridge power converters.  

### **Features:**
- **Dual Independent Drivers:** Each channel can drive a MOSFET independently.  
- **High Peak Output Current:** ±2A for fast switching.  
- **Low Propagation Delay:** Ensures precise timing in high-frequency applications.  
- **Under-Voltage Lockout (UVLO):** Protects against insufficient supply voltage.  
- **Cross-Conduction Prevention:** Prevents shoot-through in bridge configurations.  
- **TTL/CMOS Compatible Inputs:** Works with logic-level control signals.
