MAX804TCPA+

Supervisors Overview

The MAX804TCPA+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin PDIP package. It monitors a single voltage input with a threshold of 3.06 V and features a manual reset capability. The device operates within a supply voltage range of 1 V to 5.5 V and includes a watchdog timer and battery backup switch. It provides active high, active low, and push-pull outputs with a reset delay time of 200 ms. The component functions at temperatures between 0°C and +70°C with a quiescent current of 75 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a battery backup switch function for power continuity
• Provides manual reset capability for user-initiated control
• Supports multiple output configurations including push-pull

Supervisors Applications

• Microprocessor system supervision

Supervisors Procurement Notes

Verify availability status as this part may be discontinued or subject to limited supply constraints. Confirm package type and pinout compatibility during integration. Check RoHS compliance documentation for regulatory adherence. Ensure operating temperature range meets application requirements. Validate datasheet specifications against current design needs before procurement.

Supervisors Selection Notes

Select this component when manual reset and watchdog timer are required alongside voltage supervision. Consider the 3.06 V threshold for specific logic level monitoring. Evaluate the 75 µA quiescent current for power-sensitive designs. Compare with other MAX804 variants if different packages or thresholds are needed. Verify output drive capabilities match load requirements.

Supervisors Part Context

This part belongs to the MAX804 series of microprocessor supervisory circuits from Analog Devices/Maxim Integrated. It shares functional similarities with other parts in the family but differs in package style and specific electrical parameters. The TCPA suffix indicates a through-hole PDIP-8 package variant. It is designed for reliable operation in embedded environments requiring robust power monitoring.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX804 family. Verify equivalent threshold voltages and output types. Confirm package dimensions match existing PCB footprints. Review updated datasheets for any parameter changes in newer revisions.
