Description and Introduction

Low Power Microprocessor Supervisory with Battery Switch-Over The SP691ACT is a microprocessor (μP) supervisory circuit manufactured by SIPEX. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** SIPEX  
- **Type:** Microprocessor (μP) supervisory circuit  
- **Voltage Monitoring:** Monitors 5V, 3.3V, or 3V power supplies  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable via external capacitor (default 200ms)  
- **Operating Voltage Range:** 1V to 5.5V  
- **Quiescent Current:** 35μA (typical)  
- **Package Options:** 8-pin SOIC, 8-pin PDIP  

### **Descriptions:**  
- The SP691ACT 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 falls below a preset threshold.  
- The reset signal remains active for a fixed delay after the voltage returns to a valid level.  

### **Features:**  
- Precision voltage monitoring for 5V, 3.3V, or 3V systems  
- Low power consumption (35μA typical)  
- Adjustable reset timeout via external capacitor  
- Manual reset input for external system control  
- Guaranteed reset output valid down to VCC = 1V  
- Available in industrial temperature range (-40°C to +85°C)  

This information is based solely on the manufacturer's datasheet and technical documentation.

- **Package Type:** 5-Pin SOT-23  

### **Descriptions:**  
- The SP691ACT monitors microprocessor power supplies and provides a reset signal if the voltage drops below a preset threshold.  
- It is designed for low-power applications and ensures proper system operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Low Quiescent Current:** Typically 6µA  
- **Manual Reset Input:** Allows for external reset control  
- **Power-On Reset (POR) Generator:** Ensures a valid reset signal at power-up  
- **Wide Operating Voltage Range:** Compatible with 1.8V to 5.5V systems  
- **Small Form Factor:** Available in a compact SOT-23 package
