Description and Introduction

【1% Accuracy, Low-Power, +3V and +5V レP Supervisory Circuits The MAX815CSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Part Number:** MAX815CSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Factory-set (e.g., 4.63V, 4.38V, 3.08V, 2.93V, etc.)  
- **Reset Timeout Period:** 140ms (min), 280ms (max)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  
- **Quiescent Current:** 25μA (typical)  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** Yes (1.6s timeout typical)  
- **Power-Fail Comparator:** No  

### **Descriptions:**  
The MAX815CSA is a μP supervisory circuit designed to monitor system power supply voltages and provide a reset signal to the microprocessor in case of power failure or brownout conditions. It integrates a watchdog timer and manual reset functionality, ensuring reliable system operation.  

### **Features:**  
- **Voltage Monitoring:** Monitors VCC and asserts reset when voltage drops below the preset threshold.  
- **Watchdog Timer:** Detects software lockups by requiring periodic toggling; triggers reset if inactive.  
- **Manual Reset Input:** Allows external push-button or logic-initiated reset.  
- **Low Power Consumption:** 25μA typical supply current.  
- **Guaranteed Reset Valid Down to VCC = 1V.**  
- **No External Components Required** (except for optional manual reset pull-up).  
- **Available in Multiple Threshold Voltages** for different system requirements.
