MAX804SCSA+

Supervisors Overview

The MAX804SCSA+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for microprocessor supervision. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.935 V with an overvoltage threshold of 3.02 V. The device provides active high, active low, and open drain outputs with a reset delay time of 200 ms. It includes a watchdog timer and battery backup switch functionality. Operating current is 50 uA, and power dissipation is 471 mW. The component is housed in an SOIC-Narrow-8 package and functions within a temperature range of 0 C to +70 C.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch capability for data retention during power loss
• Multiple output configurations including active high, active low, and open drain

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance details via official documentation. Check regional availability restrictions as Mouser indicates non-sale in certain areas. Ensure package integrity matches SOIC-Narrow-8 specifications upon receipt.

Supervisors Selection Notes

Select this component when a fixed 2.935 V threshold is required for 3V or 3.3V MPU supervision. Consider the integrated watchdog and battery backup features if system resilience against brownouts is critical. Verify that the SOIC-Narrow-8 package fits the PCB layout constraints. Compare operating current and reset delay times against alternative supervisory ICs to ensure compatibility with target microprocessor timing requirements.

Supervisors Part Context

This part belongs to the MAX804S series of supervisory circuits from Maxim Integrated, now part of Analog Devices. These devices are specialized for monitoring power rails in embedded systems. The SCSA suffix denotes the specific package type and temperature range. This series is distinct from other MAX80x variants which may offer different thresholds or additional features like manual resets.
