MAX807LCPE+

Supervisors Overview

The MAX807LCPE+ is a full-featured supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a reset threshold voltage of 4.425 V with an overvoltage threshold of 4.5 V. The device provides active high and active low outputs, manual reset capability, and includes a watchdog timer and battery backup switch. It has a reset delay time of 280 ms and consumes 70 uA of operating current. The component is housed in a TSSOP-16 package for surface mount installation and functions within a temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Integrates manual reset input for user-initiated system control
• Includes built-in watchdog timer for automated fault recovery
• Supports battery backup switching for continuous monitoring during power transitions

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Industrial control system reset circuits

Supervisors Procurement Notes

Verify the specific suffix 'L' indicates the 4.425 V threshold variant against the official datasheet. Confirm the '+T' or standard tape/reel packaging requirements if applicable, as availability may vary. Ensure the TSSOP-16 footprint matches the design layout. Check for RoHS compliance documentation. Validate that the 0°C to +70°C commercial temperature range meets the operational environment specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with both active high and low outputs is required. The integrated manual reset and watchdog features reduce external component count compared to basic supervisors. Verify that the 70 uA quiescent current aligns with power budget constraints. Ensure the 280 ms reset delay is compatible with the target microprocessor startup timing requirements.

Supervisors Part Context

This part belongs to the MAX807M series of full-featured supervisory circuits. It shares functional similarities with other Maxim Integrated supervisors but is distinguished by its specific threshold voltages and output configurations. The series is designed for reliable operation in embedded systems requiring robust power management and fault detection capabilities.

Supervisors Replacement Considerations

Direct substitutes include the MAX807MCUE+T and MAX807MEUE+, which share similar feature sets. Verify pin compatibility and threshold voltage accuracy before substitution. Cross-reference datasheets to ensure equivalent reset delay and current consumption characteristics.
