MAX816CSA+T

Supervisors Overview

The MAX816CSA+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOIC-8 surface-mount package. It features adjustable threshold voltages for monitoring power rails and supports active high, active low, and push-pull output configurations. The device includes manual reset functionality and detects power failures without a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V, with a reset delay of 200 ms and accuracy of 1%. Operating temperatures span from -40°C to +85°C, consuming 85 uA of quiescent current.

Supervisors Feature Summary

• Provides precise voltage supervision with adjustable thresholds for flexible system monitoring.
• Offers versatile output options including active high, active low, and push-pull modes.
• Integrates manual reset capability for controlled system recovery.
• Detects power failure events to ensure data integrity during voltage anomalies.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered systems requiring low quiescent current
• Industrial control units needing wide temperature operation
• Portable electronic devices with strict power constraints

Supervisors Procurement Notes

Verify the specific suffix CSA+T against official datasheets to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors. Ensure the operating temperature range matches your environmental requirements. Cross-reference the part number with the latest Analog Devices documentation to avoid obsolete variants.

Supervisors Selection Notes

Select this component when adjustable voltage thresholds are required alongside low power consumption. The SOIC-8 package suits space-constrained printed circuit board designs. Consider the 1% accuracy and 200 ms reset delay for timing-sensitive applications. Evaluate the manual reset feature if external user intervention is needed for system recovery.

Supervisors Part Context

This part belongs to the MAX816 series of microprocessor supervisory circuits designed for low-power applications. It complements other Maxim Integrated voltage monitors by offering adjustable thresholds rather than fixed values. The series targets embedded systems requiring reliable power management without complex external components.
