MAX6332UR18D3+

Overview

The MAX6332UR18D3+ is a microprocessor supervisory circuit from the MAX6332/33/34 family, designed for 1.8V to 3.3V systems. It monitors a single voltage input and asserts an active-high push-pull RESET output when VCC drops below the 1.8V threshold. The device operates within a supply range up to 5.5V and features a reset timeout period of 100ms minimum. It functions across an extended temperature range of -40°C to +125°C in a compact SOT-23-3 package.

Feature Summary

Asserts active-high reset signal upon undervoltage detection
Push-pull output driver eliminates external pull-up components
Fixed 1.8V threshold ensures precise monitoring for low-voltage logic

Applications

Microprocessor power supply supervision
Digital system voltage monitoring
Battery-powered equipment protection

Procurement Notes

Verify the specific suffix D3 against the manufacturer datasheet to confirm the active-high output configuration, as other variants in this series utilize different output polarities. Ensure the ordering part number matches the required pinout and electrical characteristics exactly. Cross-reference with Analog Devices documentation to validate availability status and lead times for production quantities.

Selection Notes

Select this component when an active-high reset signal is required for downstream logic compatibility. The push-pull output simplifies PCB layout by removing the need for external pull-up resistors. Compare the fixed 1.8V threshold against system requirements to ensure it aligns with the target microprocessor's valid operating voltage window.

Part Context

This device belongs to the MAX6332/MAX6333/MAX6334 family of ultra-low-voltage supervisors. While the MAX6333 offers an active-low push-pull output and the MAX6334 provides an active-low open-drain output, the MAX6332 specifically delivers an active-high push-pull signal. All three share similar low-power consumption and compact packaging profiles.
