Description and Introduction

Power-Supply Monitor with Reset The **MAX709SESA+** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or factory-set (e.g., 4.65V, 4.40V, 3.08V, etc.)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 35μA (typ)  

### **Descriptions:**
- Monitors system voltage and provides a reset signal to the μP during power-up, power-down, or brownout conditions.  
- Ensures reliable system operation by holding the μP in reset until the supply voltage stabilizes.  
- Available in fixed or adjustable threshold versions.  

### **Features:**
- **Precision Voltage Monitoring:** Ensures accurate reset triggering.  
- **Low Power Consumption:** 35μA typical supply current.  
- **Manual Reset Input:** Allows external pushbutton reset control.  
- **Guaranteed Reset Valid Down to VCC = 1V:** Ensures reliable operation even at low voltages.  
- **No External Components Required:** Simplifies circuit design.  
- **Space-Saving 8-Pin SO Package:** Suitable for compact designs.
