Description and Introduction

±1% Accuracy, Low-Power, +3V and +5V µP Supervisory Circuits The MAX814TCSA+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated.  

### **Specifications:**  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** 2.63V, 2.93V, 3.08V, 4.38V, 4.63V  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Manual Reset Input:** Active-low (MR)  
- **Power-On Reset (POR) Delay:** Guaranteed after VCC reaches 1V  
- **Low Quiescent Current:** 40μA (typical)  

### **Descriptions:**  
The MAX814TCSA+ 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 initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- Precision voltage monitoring for μP and digital systems  
- Active-low reset output (RESET)  
- Manual reset input (MR) for external control  
- No external components required  
- Guaranteed reset valid down to VCC = 1V  
- Low power consumption  

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