Description and Introduction

High efficiency synchronous step-down switching regulators The LTC1159IS is a high-side micropower MOSFET driver manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LTC1159IS  
- **Type:** High-Side MOSFET Driver  
- **Supply Voltage Range:** 4V to 18V  
- **Quiescent Current:** 50µA (typical)  
- **Output Current:** Up to 250mA (peak)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
The LTC1159IS is designed to drive N-channel MOSFETs in high-side applications. It features micropower operation, making it suitable for battery-powered systems. The device includes an internal charge pump to provide gate drive voltage above the supply rail, ensuring proper MOSFET turn-on.  

### **Features:**  
- High-side N-channel MOSFET driver  
- Internal charge pump for gate drive  
- Low quiescent current (50µA typical)  
- Wide supply voltage range (4V to 18V)  
- Fast rise and fall times for efficient switching  
- Thermal shutdown protection  
- Under-voltage lockout (UVLO) protection  

This information is based solely on the manufacturer's datasheet and specifications.

Description and Introduction

High efficiency synchronous step-down switching regulators The LTC1159IS is a high-speed, dual MOSFET driver manufactured by Linear Technology (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
- Linear Technology (LT)  

### **Part Number:**  
- LTC1159IS  

### **Description:**  
- The LTC1159IS is a dual high-speed MOSFET driver designed to drive both N-channel and P-channel power MOSFETs in synchronous rectification applications.  

### **Key Features:**  
1. **Dual Independent Drivers:**  
   - Two separate drivers for high-side and low-side MOSFETs.  

2. **High-Speed Operation:**  
   - Fast rise and fall times (typically 30ns).  

3. **Wide Supply Voltage Range:**  
   - Operates from 4.5V to 18V.  

4. **Low Quiescent Current:**  
   - Typically 200µA when disabled.  

5. **Adjustable Dead Time:**  
   - External resistor allows dead-time control between high-side and low-side drivers.  

6. **Logic-Level Inputs:**  
   - Compatible with TTL and CMOS logic levels.  

7. **Thermal Shutdown Protection:**  
   - Prevents damage from excessive heat.  

8. **Under-Voltage Lockout (UVLO):**  
   - Ensures proper operation by disabling outputs when supply voltage is too low.  

### **Applications:**  
- Synchronous buck converters  
- DC/DC converters  
- Motor drives  
- Power supply circuits  

### **Package:**  
- 16-Lead SOIC (Small Outline Integrated Circuit)  

### **Operating Temperature Range:**  
- Industrial grade: -40°C to +85°C  

This information is based on the manufacturer's datasheet and specifications. For detailed electrical characteristics and application circuits, refer to the official documentation.
