MAX6368LKA29+T

Overview

The MAX6368LKA29+T is a low-power microprocessor 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 fixed threshold voltage of 2.93 V for the monitored input. The device provides an active-low, push-pull reset output with a typical reset delay time of 280 ms. It includes battery backup switching and chip-enable gating capabilities while lacking manual reset or watchdog timer functions. The component is housed in an SOT-23-8 package and supports surface-mount installation.

Feature Summary

• Integrates battery backup switching functionality to maintain system state during power transitions.
• Includes chip-enable gating to control circuit operation based on enable signals.
• Delivers a push-pull active-low reset output for reliable logic interfacing.

Applications

• Microprocessor power supply monitoring
• Battery backup systems
• Portable electronic devices

Procurement Notes

Verify the specific suffix 'LKA29' against official datasheets to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list limited stock or obsolete status. Ensure the active-low push-pull output configuration matches the target design requirements before procurement.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage supervision. The push-pull output type offers stronger drive capability compared to open-drain alternatives. Verify that the absence of a manual reset pin and watchdog timer aligns with the system's safety architecture. Ensure the operating temperature range of -40 C to +85 C meets environmental specifications.

Part Context

This part belongs to the MAX6368 series of low-power uP supervisory ICs. The 'L' suffix typically denotes specific electrical characteristics or package variations within the Maxim Integrated portfolio. It is designed for applications requiring minimal quiescent current and compact footprint solutions in portable electronics.

Replacement Considerations

Cross-reference with MAX6368LKA29+ for identical specifications without tape-and-reel packaging. Consider MAX6367HKA29+T if open-drain output is acceptable instead of push-pull. Verify functional compatibility with MAX6365LKA29+T regarding battery backup and chip-enable features.
