Description and Introduction

High Voltage 1A Peak Half Bridge Gate Driver 8-SOIC -40 to 125 The LM5109BMA is a high-voltage gate driver manufactured by Texas Instruments (NS). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (NS)  
- **Type:** High-Voltage Half-Bridge Gate Driver  
- **Operating Voltage (VDD):** 8V to 14V  
- **Maximum Bootstrap Voltage (VBST):** 118V  
- **Peak Output Current (Source/Sink):** 1.5A / 2.5A  
- **Propagation Delay (Typical):** 50ns  
- **Rise/Fall Time (10V, 1000pF Load):** 15ns / 10ns  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
The LM5109BMA is designed to drive both high-side and low-side N-channel MOSFETs in a half-bridge configuration. It features a high-voltage bootstrap diode and can operate with a floating high-side driver up to 118V. The device is optimized for high-frequency switching applications, such as motor drives, power supplies, and DC-DC converters.

### **Features:**  
- **High-Voltage Operation:** Supports up to 100V DC rail  
- **Integrated Bootstrap Diode:** Eliminates the need for an external diode  
- **Robust Gate Drive:** 1.5A source / 2.5A sink current capability  
- **UVLO Protection:** Under-voltage lockout for both VDD and VBS  
- **Matched Propagation Delays:** Ensures minimal dead time  
- **Wide Temperature Range:** Suitable for industrial applications  
- **Small Footprint:** 8-Pin SOIC package for space-constrained designs  

This information is strictly based on the manufacturer's datasheet.
