SP692AEP-L

Supervisors Overview

The SP692AEP-L is a low-power microprocessor supervisory circuit manufactured by Sipex, housed in an 8-pin PDIP package. It features two channels with adjustable thresholds and includes a watchdog timer with a 1.6-second timeout. The device provides a precision voltage monitor set at 4.40V for the SP692A variant, ensuring reliable system reset generation. It supports battery backup switchover to maintain data integrity during power transitions. Operating temperatures range from -40°C to +85°C, making it suitable for industrial applications.

Supervisors Feature Summary

• Integrates a watchdog timer with a fixed 1.6-second timeout period for system reliability.
• Provides automatic battery switchover capability to preserve external memory data.
• Includes a precision voltage monitor calibrated at 4.40V for accurate supervision.
• Offers a reset time delay of 200ms to ensure stable power-up sequencing.

Supervisors Applications

• Microprocessor supervisory circuits requiring precise voltage monitoring
• Systems utilizing external LPSRAM with battery backup requirements
• Industrial control units operating within extended temperature ranges

Supervisors Procurement Notes

Verify the manufacturer source carefully, as this component is frequently distributed by secondary suppliers like Rochester Electronics rather than direct original equipment manufacturing lines. Confirm that the specific orderable part number matches the exact package style and lead-free status required for your assembly process. Ensure compatibility with existing board layouts designed for standard DIP-8 footprints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a dedicated supervisory solution with integrated watchdog functionality is required without additional discrete components. The 4.40V threshold makes it appropriate for systems where the main supply operates near this level or requires specific trip points. Consider the PDIP package constraints if surface-mount alternatives are preferred for high-volume automated assembly processes.

Supervisors Part Context

This device belongs to the Sipex SP690/692/802/805 series of low-power microprocessor supervisors. These parts are designed to provide essential system management functions including reset generation, voltage monitoring, and watchdog timing in a compact form factor. The series is widely used in embedded systems requiring robust power management and fault detection capabilities.

Supervisors Replacement Considerations

The SP692ACN is a documented alternative within the same family offering similar supervisory functions. Verify pinout compatibility and electrical specifications against the SP692AEP-L datasheet before substitution to ensure functional equivalence in the target application.
