MAX6367PKA29+T

Overview

The MAX6367PKA29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed reset threshold voltage of 2.90 V. The device provides an active-high, open-drain reset output with a typical reset delay time of 280 ms. It includes a battery backup switch for seamless power transition and a chip-enable input for power management control. Packaged in an SOT-23-8 surface-mount case, it supports operation from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to maintain system state during power transitions
• Includes a chip-enable input for controlled power-down and standby modes
• Provides an active-high, open-drain reset output signal

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing backup power switching
• Microprocessor reset circuits in industrial environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for AEC-Q100 automotive qualification if required for specific applications. Review current lifecycle status as availability may be limited. Ensure proper handling procedures are followed for the SOT-23-8 package during assembly.

Selection Notes

Select this component when an active-high reset output is required rather than the more common active-low configuration. The integrated battery backup switch simplifies design for systems maintaining volatile memory. Verify that the 2.90 V threshold aligns with the monitored rail voltage. Consider the open-drain output requirement for pull-up resistor implementation in the target circuit design.

Part Context

This part belongs to the MAX6367P series of low-power supervisors. It shares functional similarities with other MAX6367 variants but differs in output polarity and threshold voltage. The 'P' suffix typically denotes specific pinout or feature configurations within the broader MAX6367 family designed for portable applications.

Replacement Considerations

Cross-reference with MAX6367HKA29+T for similar functionality but note the difference in reset output polarity (active-low vs. active-high). Verify compatibility with existing board layouts due to potential differences in internal circuitry despite identical packaging.
