Description and Introduction

Microprocessor supervisory circuit. Reset threshold 2.93V. Active-low reset. Watchdog input. Manual reset input. The MAX823SEUK is a microprocessor (µP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX823SEUK  
- **Type:** µP Supervisory Circuit  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or Fixed (1.6V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 5µA (typical)  

### **Descriptions:**
The MAX823SEUK monitors microprocessor power supply voltages and provides a reset signal to the µP during power-up, power-down, or brownout conditions. It ensures proper system operation by holding the µP in reset until the supply voltage stabilizes.  

### **Features:**
- **Low Power Consumption:** 5µA typical supply current  
- **Precision Voltage Monitoring:** Ensures reliable µP reset  
- **Manual Reset Input:** Allows external pushbutton reset  
- **Wide Operating Voltage Range:** 1.2V to 5.5V  
- **Small Package:** SOT-23-5 for space-constrained applications  
- **Guaranteed Reset Output Valid to VCC = 1V**  
- **No External Components Required** (for fixed threshold versions)  

This information is based solely on manufacturer-provided data.
