Overview
The MAX6332UR24D1-T is a 3-pin, ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5.5V and features an active-high push-pull RESET output. The device monitors the VCC supply voltage and asserts the reset signal when the voltage declines below a preset threshold of 2.4V. It maintains this assertion for a timeout period of 1ms after VCC rises above the threshold. The circuit consumes only 3.3µA of quiescent current and functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Provides reliable power-supply supervision with an active-high push-pull output for direct interface compatibility.
Applications
- Monitoring power supplies in 1.8V to 3.3V microprocessor systems
- Digital system voltage supervision
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your project requirements. Ensure the SOT-23-3 package dimensions match your PCB footprint design before finalizing procurement decisions.
Selection Notes
Select this component when an active-high reset signal is required for microprocessor supervision. It is suitable for applications needing a short 1ms timeout period and low quiescent current consumption. Consider alternative models like MAX6333 if an active-low output is preferred instead.
Part Context
This part belongs to the MAX6332/MAX6333/MAX6334 family of 3-pin, ultra-low-voltage, low-power µP reset circuits. These devices eliminate external components and adjustments by integrating fixed threshold voltages and timeout periods into a single compact package.
Replacement Considerations
MAX6332UR24D1+T serves as a lead-free variant of this component. Other family members include MAX6333 (active-low) and MAX6334 (open-drain), which share similar electrical characteristics but differ in output configuration.
