Description and Introduction

Micropower Precision Triple Supply Monitors in 8-Lead MSOP and 5-Lead SOT-23 Packages The LTC1728ES5-3.3#PBF is a microprocessor supervisory circuit manufactured by Linear Technology (now part of Analog Devices). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Supply Current:** 6µA (typical)  
- **Operating Voltage Range:** 1.5V to 5V  
- **Reset Timeout Period:** 140ms (minimum)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**
- The LTC1728ES5-3.3#PBF monitors 3.3V microprocessor power supplies and generates a reset signal when the supply voltage falls below a preset threshold.  
- It ensures proper system operation by holding the microprocessor in reset during power-up, power-down, and brownout conditions.  
- The device features a manual reset input for additional control.  

### **Features:**
- **Low Power Consumption:** Only 6µA typical supply current.  
- **Precision Monitoring:** ±1.5% reset threshold accuracy.  
- **Guaranteed Reset Assertion:** Down to VCC = 1V.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Small Form Factor:** SOT-23-5 package for space-constrained applications.  
- **No External Components Required:** Simplifies design.  

This device is commonly used in embedded systems, industrial controls, and battery-powered applications requiring reliable power monitoring.
