MAX801MCSA+

Supervisors Overview

The MAX801MCSA+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin SOIC surface-mount package. It monitors a single input with a threshold voltage of 4.425 V and offers a reset accuracy of 1.5%. The device supports active high, active low, and push-pull output configurations without manual reset functionality. Key features include an integrated watchdog timer and battery backup switch. It operates within a supply voltage range up to 5.5 V, consumes 68 uA of quiescent current, and provides a reset delay time of 200 ms. The component functions reliably across a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault detection
• Includes a battery backup switch for power loss monitoring
• Provides configurable active high, active low, or push-pull outputs

Supervisors Applications

• Microprocessor reset circuits
• Power supply monitoring systems
• Battery backup switching applications

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through authorized channels. Check current availability as distribution may be limited. Ensure the selected package variant matches the intended PCB layout requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when precise voltage supervision with integrated watchdog capabilities is required. The 1.5% reset accuracy suits applications demanding stable threshold detection. Consider the SOIC-8 package for space-constrained designs. Evaluate the 68 uA quiescent current against total system power budgets. Verify that the absence of a manual reset input aligns with the system control architecture.

Supervisors Part Context

This part belongs to the MAX801M series of microprocessor supervisory circuits from Analog Devices/Maxim Integrated. These devices are designed to monitor power supplies and ensure reliable system operation. The MAX801 variant specifically combines voltage supervision with watchdog and backup functionalities in a compact form factor suitable for embedded electronics.
