Description and Introduction

Power-Supply Monitor with Reset The MAX709TCSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX709TCSA  
- **Package:** SOIC-8  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 35μA (typ)  

### **Descriptions:**  
The MAX709TCSA monitors microprocessor power supplies to ensure proper system operation. It asserts a reset signal when the supply voltage drops below a preset threshold, preventing erratic behavior during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures reliable reset generation.  
- **Manual Reset Input:** Allows external reset control.  
- **Low Quiescent Current:** 35μA (typ) for power efficiency.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Guaranteed Reset Assertion:** Valid down to VCC = 1V.  
- **No External Components Required:** Simplifies design.  

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

Application Scenarios & Design Considerations
