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.

Application Scenarios & Design Considerations

Low Power Microprocessor Supervisory with Battery Switch-Over

Alternative Part Number

  • MAX691ACPE --: Pin-compatible microprocessor supervisory circuit with the same functions (reset, watchdog, battery switchover) and widely available as a drop-in replacement.
  • ADM691AN --: Equivalent supervisory IC from a different series with matching pinout and electrical characteristics, suitable for direct substitution.
  • ICL691CPE --: Alternative supervisory circuit in the same family class with comparable reset threshold and watchdog timing, usable with minor verification.
  • DS1232 --: Microprocessor supervisor with reset and watchdog capability that can serve similar system monitoring roles when pin mapping is adapted.
