MAX6332UR20D3

Overview

The MAX6332UR20D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed threshold voltage of 2.0V. The device provides an active-low, push-pull reset output with a typical reset delay time of 200ms. It consumes a maximum quiescent current of 4.0µA and functions reliably across an industrial temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount format, it lacks manual reset, watchdog timer, or battery backup switching capabilities.

Feature Summary

• Provides precise voltage monitoring with a fixed 2.0V threshold for system supervision
• Delivers a robust active-low push-pull reset signal for direct logic interfacing
• Optimized for low-power applications with ultra-low quiescent current consumption
• Operates effectively across extended industrial temperature ranges

Applications

• Microprocessor power supply monitoring
• Battery-powered portable equipment supervision
• Handheld instrumentation voltage tracking
• Consumer electronics power management

Procurement Notes

Verify the specific suffix D3 indicates the 2.0V threshold variant during sourcing. Confirm RoHS compliance status as required by project specifications. Check manufacturer lifecycle status for long-term availability assurance. Validate package integrity upon receipt to ensure pin alignment matches SOT-23-3 standards.

Selection Notes

Select this component when a fixed 2.0V threshold is required for system supervision. Choose the push-pull output configuration if driving logic inputs directly without external pull-ups. Consider the 200ms delay duration against system startup requirements. Evaluate the SOT-23-3 footprint constraints against available PCB real estate.

Part Context

This part belongs to the MAX6332 series of uPower Reset Circuits designed for critical voltage monitoring. It complements other variants in the family offering different thresholds and output configurations. The series targets applications requiring reliable power supervision in space-constrained designs.

Replacement Considerations

Cross-reference with MAX6332UR20D2+T for identical electrical performance but potential packaging differences. Verify compatibility with MAX6332UR20D3+TR regarding reel specifications. Ensure substitute parts maintain the same 2.0V threshold and push-pull output characteristics.
