MAX6336US24D1-T

Overview

The MAX6336US24D1-T is a 4-pin, ultra-low-voltage, low-power microprocessor reset circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage input with a fixed threshold of 2.4V and provides an active-low, push-pull/totem-pole output. The device features a manual reset input and operates within a supply voltage range up to 5.5V. It offers a typical reset timeout of 1ms and consumes minimal quiescent current. The component is designed for surface-mount installation in the SOT-143-4 package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates a manual reset button input for user-initiated system control alongside automatic power-supply monitoring.
• Delivers a robust push-pull/totem-pole output stage capable of driving downstream logic directly without external pull-up resistors.
• Optimized for ultra-low-voltage applications with fixed threshold detection suitable for modern low-power embedded systems.

Applications

• Embedded systems requiring reliable power supervision for microprocessors and memory devices.
• Portable electronic equipment utilizing battery supplies where low quiescent current is critical.
• Industrial control units operating in extended temperature environments.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices or Maxim Integrated, as both entities are associated with this product line. Ensure the part number matches the exact threshold voltage variant required for your design. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a fixed 2.4V threshold is appropriate for the monitored rail. The inclusion of a manual reset pin distinguishes it from simpler reset ICs lacking user intervention capabilities. Consider the SOT-143-4 footprint for space-constrained PCB layouts. Evaluate the push-pull output drive strength against the capacitive load of the target reset line to ensure signal integrity during transitions.

Part Context

This part belongs to the MAX6336 family of ultra-low-voltage reset circuits. The series is characterized by its ability to operate at very low supply voltages while maintaining precise threshold accuracy. The US24D1 designation specifically denotes the 2.4V threshold variant in the SOT-143-4 package with manual reset functionality.

FAQ
