MAX6336US23D3-T

Overview

The MAX6336US23D3-T is an ultra-low voltage, low-power microprocessor reset circuit manufactured by Analog Devices (Maxim Integrated). It operates within a supply voltage range of 1.0V to 5.5V and features a fixed 2.3V threshold for the reset output. The device provides a push-pull or open-drain reset signal with a typical timeout period of 140ms. It includes manual reset functionality via an external pin and offers high immunity to power-supply noise. The component is housed in a compact 4-pin SOT-143 package.

Feature Summary

• Ultra-low voltage operation supporting systems down to 1.0V
• Integrated manual reset input for system control
• High noise immunity against power-supply transients
• Compact 4-pin SOT-143 surface-mount packaging

Applications

• Portable battery-powered electronic devices
• Microprocessor and microcontroller supervisory circuits
• Low-voltage digital logic systems
• Handheld instrumentation and consumer electronics

Procurement Notes

Verify the specific suffix 'D3' indicates the tape-and-reel packaging configuration when ordering. Confirm the 'T' designation aligns with the required reel quantity from the manufacturer's current documentation. Ensure the part number matches the exact 2.3V threshold variant required for the design. Cross-reference the datasheet revision date to confirm compatibility with existing board designs.

Selection Notes

Select this component when a fixed 2.3V reset threshold is required for ultra-low voltage applications. It is suitable for designs needing manual reset capability alongside automatic power-on reset. Consider the SOT-143 package size constraints and the need for push-pull output drive. Evaluate the 140ms timeout duration against the target processor's startup requirements.

Part Context

This part belongs to the MAX6336 family of microprocessor supervisory circuits designed for low-power applications. The series offers various fixed voltage thresholds and packaging options. The US23 variant specifically targets the 2.3V monitoring requirement. It complements other Maxim integrated circuits for complete power management solutions in portable devices.

Replacement Considerations

Check for direct cross-reference part numbers from Analog Devices or third-party manufacturers offering identical 2.3V thresholds and SOT-143 packages. Verify pinout compatibility before substitution. Ensure equivalent electrical characteristics such as timeout duration and quiescent current are met.
