Description and Introduction

±1% Accuracy, Low-Power, +3V and +5V µP Supervisory Circuits The MAX814KCSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX814KCSA+  
- **Type:** Microprocessor Supervisory Circuit  
- **Package:** 8-Pin SOIC  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or Fixed (4.38V, 4.63V, or 4.88V)  
- **Reset Timeout Period:** 140ms (min), 280ms (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 12μA (typ)  

### **Descriptions:**
The MAX814KCSA+ monitors the power supply voltage of a microprocessor and provides a reset signal if the voltage drops below a preset threshold. It ensures proper system operation by holding the microprocessor in reset until the supply voltage stabilizes.  

### **Features:**
- Precision voltage monitoring for 3V, 3.3V, and 5V systems  
- Manual reset input  
- Guaranteed reset output valid down to VCC = 1V  
- Low quiescent current (12μA typical)  
- No external components required for fixed threshold versions  
- Power-fail comparator for early warning of power failure  
- Available in 8-pin SOIC package  

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