Description and Introduction

Low Power Microprocessor Supervisory with Battery Switch-Over The part **SP691ACT** is manufactured by **SP** (Silicon Precision). Below are the specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Manufacturer:** SP (Silicon Precision)  
- **Type:** Voltage Monitor / Reset IC  
- **Operating Voltage Range:** Typically 1.8V to 5.5V  
- **Reset Threshold Accuracy:** High precision (exact value depends on variant)  
- **Output Type:** Active-low or active-high reset (depends on variant)  
- **Package Type:** SOT-23, SC-70, or similar small form factor  
- **Operating Temperature Range:** Typically -40°C to +85°C  

### **Descriptions:**  
- The SP691ACT is a voltage monitoring IC designed to provide a reset signal to microcontrollers or other digital systems when the supply voltage falls below a specified threshold.  
- It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Manual Reset Capability:** Some variants include a manual reset input.  
- **Wide Operating Voltage Range:** Supports various logic levels.  
- **Small Package Options:** Ideal for space-constrained designs.  

For exact threshold voltages, timing characteristics, and pin configurations, refer to the official **SP691ACT datasheet** from Silicon Precision (SP).

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 direct replacement.
  • ADM691AN --: Equivalent supervisory IC offering reset generation, watchdog timer, and backup battery switching in a compatible DIP package.
  • DS1232 --: Alternative microprocessor supervisor providing reset and watchdog functions; verify pinout and threshold before substitution.
  • ICL691CPE --: Same-function supervisory circuit from a different series, offering comparable reset and watchdog features for drop-in substitution.
