MAX6336US25D3+

Overview

The MAX6336US25D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage channel with a fixed threshold of 2.5V. The device features an active-low, push-pull/totem pole output and provides a minimum reset timeout of 20ms. It operates within a supply voltage range up to 5.5V and supports surface mount installation in a SOT-143-4 package. The component functions across a temperature range of -40°C to +125°C.

Feature Summary

• Monitors power supply voltage against a preset threshold to ensure system reliability
• Provides debounced manual-reset input functionality for user-initiated control
• Delivers active-low reset signal via push-pull output stage

Applications

• Microprocessor (µP) systems requiring voltage supervision
• Digital systems operating within the 1.8V to 3.3V range
• Applications necessitating manual reset capability

Procurement Notes

Verify the specific suffix D3 regarding reset timeout characteristics against official datasheets, as variations exist within the MAX6336 family. Confirm RoHS compliance status (+ suffix) and package type (SOT-143-4). Check current availability as distribution channels may list this part as discontinued or limited stock. Ensure the selected variant matches the required 2.5V threshold and active-low output configuration for the target design.

Selection Notes

Select this component when a fixed 2.5V threshold is required for ultra-low-voltage monitoring. The SOT-143-4 package suits space-constrained surface-mount designs. Consider the active-low push-pull output for direct interfacing with logic inputs. Verify that the 20ms minimum reset timeout aligns with the system's power-up sequence requirements. Compare against other MAX633x variants if different thresholds or manual reset features are needed.

Part Context

The MAX6336 belongs to the Maxim Integrated µP Reset Circuit family, designed to monitor power supplies in low-voltage digital systems. These circuits eliminate external components by integrating threshold detection and reset generation. The MAX6336 specifically offers a manual reset input, enhancing flexibility for system control compared to basic power-on-reset-only devices.

Replacement Considerations

Cross-reference with MAX6336US25D2+T for alternative reset timeout specifications within the same package and threshold. Verify functional compatibility with MAX6337 series if open-drain outputs are preferred over push-pull.
