MAX690SCSA+T

Supervisors Overview

The MAX690SCSA+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-SOIC surface-mount package. It features a fixed threshold voltage of 2.925V and provides an active-low push-pull reset output with a minimum reset timeout of 140ms. The device monitors a single input channel and includes power-fail detection capabilities without manual reset functionality. It operates within a temperature range of 0°C to +70°C and supports battery backup switching for system reliability.

Supervisors Feature Summary

• Integrated watchdog timer for automated system recovery
• Battery backup switching capability for data retention
• Power-fail warning detection mechanism

Supervisors Applications

• Microprocessor system supervision
• CMOS RAM backup switching
• Low-power logic monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the SOIC-8 package matches design specifications. Validate that the 2.925V threshold aligns with target supply voltage levels before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.925V threshold is required for precise low-voltage monitoring. Consider the 140ms reset delay for timing-sensitive applications. The industrial-grade temperature range suitability should be evaluated against environmental conditions. Verify compatibility with active-low reset logic interfaces.

Supervisors Part Context

This part belongs to the MAX690 series of microprocessor supervisory circuits designed to enhance system reliability. It integrates multiple functions typically requiring discrete components into a single IC. The series is engineered to reduce complexity while providing essential protection against brownout conditions and power failures.

Supervisors Replacement Considerations

MAX690SCSA+ is confirmed as a compatible alternative with identical electrical characteristics but in a tube package instead of tape and reel.
