Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 2.625V. Active-low reset. Watchdog input. Backup-battery switch. Power-fail threshold accuracy +-4%. Power-fail comparator. Reset window +-75mV The **MAX690RESA** is a microprocessor (μP) supervisory circuit manufactured by **Maxim Integrated** (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or fixed (e.g., 4.65V for 5V systems)  
- **Reset Timeout Period:** Typically 200ms (adjustable with external capacitor)  
- **Quiescent Current:** Low (typically 5μA)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The **MAX690RESA** is 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 specified threshold.  
- It includes a manual reset input for external system control.  
- The device is commonly used in embedded systems, industrial controls, and battery-powered applications.  

### **Features:**
- **Voltage Monitoring:** Provides reset signals when VCC falls below a preset threshold.  
- **Manual Reset Input:** Allows for external reset triggering.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Wide Operating Voltage Range:** Supports 1.2V to 5.5V systems.  
- **Adjustable Reset Timeout:** Can be modified using an external capacitor.  
- **Small Form Factor:** 8-pin SOIC package for space-constrained designs.

Description and Introduction

3.0V or 3.3V microprocessor supervisory circuit. Reset threshold 2.625V. Active-low reset. Watchdog input. Backup-battery switch. Power-fail threshold accuracy +-4%. Power-fail comparator. Reset window +-75mV The MAX690RESA is a microprocessor (µP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about the part:

### **Manufacturer:**  
- **MAXIM** (now part of Analog Devices)  

### **Specifications:**  
- **Part Number:** MAX690RESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 12µA (typical)  
- **Manual Reset Input:** Yes (active-low)  
- **Watchdog Timer:** Yes (1.6s timeout, typical)  
- **Battery Backup Switch:** Yes (for CMOS RAM or real-time clock backup)  

### **Descriptions:**  
The MAX690RESA is a low-power µP supervisory circuit designed to monitor power supply voltages in microprocessor-based systems. It provides reset signals during power-up, power-down, and brownout conditions to ensure proper system operation. The device includes a watchdog timer, manual reset input, and a backup battery switch for data retention.  

### **Features:**  
- **Power Supply Monitoring:** Ensures µP reset during voltage drops.  
- **Low Quiescent Current:** 12µA (typical) for power efficiency.  
- **Watchdog Timer:** Prevents system lockup by requiring periodic µP activity.  
- **Battery Backup Switching:** Automatically switches to backup power during main power failure.  
- **Manual Reset Input:** Allows external reset triggering.  
- **Wide Supply Voltage Range:** Operates from 1.2V to 5.5V.  
- **Industrial Temperature Range:** -40°C to +85°C.
