MAX6336US18D3+T

Overview

The MAX6336US18D3+T is a 4-pin, ultra-low-voltage, low-power microprocessor reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended temperature range of -40°C to +125°C and features a fixed overvoltage threshold of 1.83V. The device draws an operating supply current of 3.3µA and supports a power dissipation of 320mW. It provides a minimum reset timeout of 100ms and utilizes a surface-mount SOT-143 package.

Feature Summary

• Monitors power supply voltage and asserts a reset signal when the supply declines below a preset threshold
• Maintains the reset assertion for a preset timeout period after the supply voltage rises above the threshold
• Features a push-pull/totem pole active-low RESET output channel

Applications

• Microprocessor (µP) supervisory circuits
• Digital systems requiring power supply monitoring
• Ultra-low-voltage applications

Procurement Notes

Verify the specific suffix 'D3' and '+T' designation against official Analog Devices documentation to confirm the exact pinout, lead finish, and tape-and-reel packaging configuration. Ensure the component matches the required 1.83V threshold and SOT-143 package dimensions for your design integration.

Selection Notes

Select this component for designs requiring a fixed 1.83V reset threshold with a push-pull output stage. It is suitable for space-constrained applications due to its compact SOT-143 footprint and low power consumption profile. Confirm compatibility with the system's voltage levels and thermal requirements before implementation.

Part Context

This part belongs to the MAX6336 family of microprocessor supervisory circuits. These devices are designed to increase circuit reliability and reduce cost by eliminating external components and adjustments typically needed for power supply monitoring in digital systems.

Replacement Considerations

Check for MAX6336 variants with different thresholds or output types (e.g., open-drain) if electrical characteristics do not match. Verify pin-to-pin compatibility with other SOT-143 supervisors from the same manufacturer.
