MAX6824YUK

Supervisors Overview

The MAX6824YUK is a single-supply voltage supervisor circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.8 V to 5.5 V and monitors a single input channel. The device features a fixed threshold voltage of 3.0 V, an active-low push-pull output, and a manual reset capability. It includes an integrated watchdog timer with a reset delay time of 320 ms. The component supports operation across a temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Provides manual reset functionality via dedicated pin
• Features low-power consumption suitable for battery applications

Supervisors Applications

• Portable electronic devices requiring power monitoring
• Microprocessor systems needing watchdog supervision
• Battery-operated equipment with low standby current requirements

Supervisors Procurement Notes

Verify the specific suffix 'YUK' against official datasheets to confirm the 3.0 V threshold and manual reset configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary. Ensure the SOT-23-5 footprint matches the design layout before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.0 V threshold is required alongside manual reset control. The integrated watchdog timer simplifies design compared to discrete solutions. Verify that the 320 ms reset delay meets system timing constraints. Consider the SOT-23-5 package size for space-constrained PCB layouts.

Supervisors Part Context

The MAX6824 belongs to the Maxim Integrated uPower Supervisor family, designed for low-voltage digital systems. This series typically combines voltage monitoring with watchdog functions in small packages. The MAX6824YUK variant specifically targets applications needing precise 3.0 V supervision with manual intervention capabilities.

Supervisors FAQ

Does the MAX6824YUK support manual reset?
