MAX6336US23D3

Overview

The MAX6336US23D3 is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed as an ultra-low-voltage, low-power microprocessor reset circuit. It operates within a supply voltage range of 1.0V to 5.5V and features a fixed threshold voltage of 2.3V for monitoring power rails. The device provides a manual reset input capability and utilizes a push-pull/totem pole output configuration with active-low assertion. Packaged in a compact SOT-143-4 surface-mount format, it supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Ultra-low-voltage operation suitable for battery-powered systems
• Manual reset input functionality for system control
• Active-low push-pull output driver
• Compact SOT-143-4 surface-mount packaging

Applications

• Portable electronic devices requiring low standby current
• Battery-operated instrumentation systems
• Microprocessor reset circuits in embedded controllers
• Power management supervision in handheld equipment

Procurement Notes

Verify the exact suffix against official Maxim Integrated documentation, as variations such as D2 or D3 indicate specific threshold voltages. Confirm RoHS compliance status and lead times through authorized distributors, noting that availability may vary due to product lifecycle stages. Ensure the package type matches design requirements before ordering.

Selection Notes

Select this component when a fixed 2.3V threshold is required for power monitoring in low-voltage applications. Consider the manual reset feature if external user intervention is needed for system recovery. Evaluate the SOT-143-4 footprint constraints against available board space. Compare power consumption metrics with alternative supervisors if extended battery life is critical.

Part Context

This part belongs to the MAX6336 family of ultra-low-voltage reset circuits. It shares functional similarities with other members like the MAX6337 but differs in output configuration and specific threshold options. The series is designed for applications demanding minimal quiescent current and reliable reset generation under varying supply conditions.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX633x series with adjusted thresholds. Verify equivalent performance in terms of reset timeout and accuracy. Consult manufacturer cross-reference guides for validated alternatives.
