Description and Introduction

High Efficiency Synchronous Step-Down Switching Regulators The LTC1159IS#PBF is a high-side micropower MOSFET driver manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** LINEAR (Linear Technology/Analog Devices)  
- **Part Number:** LTC1159IS#PBF  
- **Package:** 16-SOIC (Narrow)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage Range:** 4V to 18V  
- **Quiescent Current:** 40µA (typical)  
- **Output Current:** Up to 250mA (peak)  
- **Propagation Delay:** 1µs (typical)  
- **Logic Input Compatibility:** TTL/CMOS  
- **Features:** Charge pump for high-side N-channel MOSFET drive  

### **Descriptions:**
The LTC1159IS#PBF is a high-side MOSFET driver designed to control N-channel MOSFETs in applications requiring efficient power switching. It includes an integrated charge pump to provide sufficient gate drive voltage for high-side configurations. The device operates with low quiescent current, making it suitable for battery-powered and energy-efficient systems.

### **Features:**
- **Micropower Operation:** Only 40µA typical quiescent current.  
- **Wide Supply Range:** Operates from 4V to 18V.  
- **High-Side Drive:** Integrated charge pump eliminates the need for an external bootstrap capacitor.  
- **Fast Switching:** 1µs typical propagation delay for quick response.  
- **TTL/CMOS Compatible Inputs:** Works with standard logic levels.  
- **Short-Circuit Protection:** Includes thermal shutdown for reliability.  
- **Low Dropout Operation:** Efficiently drives MOSFETs even at low supply voltages.  

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