Description and Introduction

Low Power Microprocessor Supervisory with Battery Switch-Over The part **SP691ACP** is manufactured by **SP** (Signal Processing). Here are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Voltage Supervisor IC  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Operating Voltage Range:** 1.2V to 5.5V  
- **Reset Threshold Accuracy:** ±1.5%  
- **Reset Timeout Period:** Adjustable or fixed (depending on variant)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The SP691ACP is a microprocessor (μP) supervisory circuit designed to monitor power supply voltages.  
- It provides a reset signal to the system when the voltage drops below a specified threshold, ensuring proper initialization.  
- Suitable for applications requiring reliable power monitoring, such as embedded systems, industrial controls, and computing devices.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows for external system reset control.  
- **Wide Voltage Range:** Supports monitoring from 1.2V to 5.5V.  
- **High Accuracy:** Tight reset threshold tolerance (±1.5%).  
- **Industrial Temperature Range:** Operates reliably in harsh environments.  

This information is strictly based on the available technical data for the SP691ACP.

Description and Introduction

Low Power Microprocessor Supervisory with Battery Switch-Over The SIPEX part SP691ACP is a microprocessor (μP) supervisory circuit designed to monitor power supplies in μP and digital systems.  

**Specifications:**  
- **Supply Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Available in fixed and adjustable versions  
- **Reset Timeout Period:** 200ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-pin PDIP (Plastic Dual In-line Package)  

**Descriptions:**  
- Monitors system power supply and generates a reset signal if the voltage falls below a preset threshold.  
- Ensures proper system initialization during power-up, power-down, and brownout conditions.  

**Features:**  
- Low quiescent current (typically 5μA)  
- Manual reset input  
- Power-on reset (POR) generator  
- Guaranteed reset output valid down to VCC = 1V  
- No external components required for fixed threshold versions
