Description and Introduction

High-Accuracy / Low-Dropout Linear Regulators The MAX689CSA is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX689CSA  
- **Package:** 8-pin SOIC  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.575V, 2.32V, 2.93V, 4.38V)  
- **Reset Timeout Period:** 140ms (min)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Quiescent Current:** 5μA (typical)  
- **Manual Reset Input:** Active-low (MR)  
- **Watchdog Timer:** 1.6s (typical)  

### **Description:**  
The MAX689CSA is a low-power μP supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It ensures proper system operation by generating a reset signal if the supply voltage drops below a preset threshold. It includes a watchdog timer, manual reset input, and an adjustable or fixed reset threshold.

### **Features:**  
- **Low Power Consumption:** 5μA typical quiescent current.  
- **Adjustable or Fixed Reset Threshold:** Supports multiple voltage options.  
- **Watchdog Timer:** Monitors system activity; resets if software fails.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Wide Supply Voltage Range:** Operates from 1.2V to 5.5V.  
- **140ms Min Reset Timeout:** Ensures stable power-up.  
- **Space-Saving 8-Pin SOIC Package:** Suitable for compact designs.  

This information is strictly based on the manufacturer's datasheet and specifications.
