MAX6864UK23D3S+T

Supervisors Overview

The MAX6864UK23D3S+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a factory-trimmed reset threshold voltage of 2.3 V. The device utilizes an active-low, push-pull output configuration and includes a manual reset input alongside a watchdog timer function. It provides a fixed reset delay time of 225 ms and consumes a typical operating supply current of 7 uA. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring, watchdog timer, and manual reset capabilities into a single five-pin package
• Features an active-low push-pull output for direct interface with microprocessor reset pins
• Includes a dedicated manual reset input allowing external assertion of the reset signal
• Maintains ultra-low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor system power supervision
• Battery-operated electronic devices requiring low standby current
• Embedded systems with watchdog timer requirements
• Portable equipment power management circuits

Supervisors Procurement Notes

Verify the specific suffix D3S to confirm the 225 ms timeout period and push-pull output type, as variations exist within the MAX6864 family. Confirm RoHS compliance status via the manufacturer datasheet. Check current availability as distribution channels may list limited stock or end-of-life status for this specific part number variant.

Supervisors Selection Notes

Select this component when a fixed 2.3 V threshold is required for single-supply monitoring. Ensure the application benefits from the push-pull output drive capability rather than open-drain configurations found in other series variants. Verify that the 225 ms reset delay aligns with the system startup timing requirements before finalizing the design.

Supervisors Part Context

This part belongs to the MAX6854 through MAX6869 series of nanopower microprocessor supervisory circuits. These devices are designed to provide essential power management functions in minimal footprint packages. The MAX6864 specifically denotes the variant with a push-pull output and manual reset input, distinguishing it from open-drain alternatives in the same family.

Supervisors Replacement Considerations

Consider MAX6864UK23D2S+T if a shorter 60 ms reset delay is acceptable. Verify compatibility with MAX6864UK23D3L+T regarding lead-free status and packaging specifications.
