Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 2.625V. Active-high reset. Watchdog input. Backup-battery switch. Power-fail threshold accuracy +-4%. Power-fail comparator. Reset window +-75mV The MAX805RCSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** SOIC-8  
- **Type:** μP Supervisory Circuit  
- **Operating Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 3.08V, 4.38V, etc.)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  

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

### **Features:**  
- Low quiescent current (6μA typical)  
- Manual reset input  
- Guaranteed reset output valid down to VCC = 1V  
- Power-on reset generation  
- No external components required for fixed threshold versions  
- Space-saving 8-pin SOIC package  

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