MAX806SCSA+

Supervisors Overview

The MAX806SCSA+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 2.935 V. The device provides an active low, push-pull output with a reset delay time of 200 ms. It supports manual reset functionality and includes a battery backup switch for power failure detection. The component consumes 50 uA of operating current and maintains an accuracy of 2%. It is housed in an SOIC-Narrow-8 package and functions reliably across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a 2% accuracy threshold for reliable system supervision
• Integrates manual reset capability allowing user-initiated system recovery
• Includes battery backup switch functionality to detect power failures during main supply loss

Supervisors Applications

• Microprocessor power supply monitoring
• Portable battery-powered equipment supervision
• Multi-output power supply management

Supervisors Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm the exact threshold voltage variant, as suffixes often denote specific trip points within the MAX806 family. Confirm RoHS compliance status through manufacturer documentation. Check current availability status as distribution channels may list limited stock or obsolete status for this specific part number.

Supervisors Selection Notes

Select this component when a fixed 2.935 V threshold is required for systems operating between 1.2 V and 5.5 V. The integrated manual reset feature distinguishes it from variants lacking this input. Ensure the SOIC-Narrow-8 package fits the PCB layout constraints. Verify that the 200 ms reset delay meets the timing requirements of the target microprocessor or logic circuit.

Supervisors Part Context

The MAX806 series consists of micropower voltage supervisors designed for monitoring power supplies in portable and industrial applications. The MAX806SCSA+ represents a specific variant within this family, characterized by its narrow SOIC-8 packaging and specific threshold settings. It belongs to the broader category of PMIC supervisory circuits used to ensure system stability during power transitions.

Supervisors Replacement Considerations

Cross-reference with MAX806MCSA+ or MAX806LCSA+ if different threshold voltages are acceptable. Verify pin compatibility with MAX804SCSA+ but note differences in watchdog timer presence and output polarity.
