MAX6366HKA29+

Overview

The MAX6366HKA29+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.6 V to 5.5 V and features a fixed threshold voltage of 2.93 V for the monitored input. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It includes a battery backup switch and chip-enable gating functionality but lacks manual reset and watchdog timer capabilities. The component is housed in an SOT-23-8 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switching and chip-enable gating for system power management
• Provides active-low open-drain reset signal generation based on voltage thresholds
• Designed for ultra-low power consumption suitable for battery-operated applications

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Embedded controller power monitoring

Procurement Notes

Verify the specific suffix 'HKA' against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution channels may list limited stock or obsolete status for this specific part number variant.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage monitoring. Ensure the application does not require a manual reset button or watchdog timer, as these features are absent. Verify that the open-drain output type aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6366P series of low-power supervisory circuits. It shares functional similarities with other Maxim Integrated supervisor ICs but is distinguished by its specific threshold voltage and integrated battery backup/enable gating features. It serves as a dedicated power management solution for systems requiring reliable reset generation under varying supply conditions.
