MAX6333UR23D2-T

Overview

The MAX6333UR23D2-T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.3 V. The device provides an active low, push-pull output with a reset delay time of 40 ms. It consumes a typical operating supply current of 3.3 uA and has an overvoltage threshold of 2.44 V. Power dissipation is rated at 320 mW. The component supports surface mount installation in an SOT-23-3 package and functions reliably across a temperature range from -40°C to +125°C.

Feature Summary

• Provides simple reset or power-on reset functionality for monitored systems
• Features ultra-low power consumption suitable for battery-operated applications
• Delivers active low push-pull output signal for direct interface compatibility

Applications

• Microprocessor supervision in embedded systems
• Battery-powered portable electronic devices
• Industrial control system monitoring

Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations like D2 versus D3 indicate specific threshold voltages. Confirm RoHS compliance status through certified datasheets. Check current lifecycle status, as this part may be discontinued or subject to limited availability. Ensure the ordering code matches the required pinout and electrical specifications precisely before procurement.

Selection Notes

Select this component when a fixed 2.3 V threshold is required for single-input voltage monitoring. The push-pull output eliminates the need for external pull-up resistors compared to open-drain alternatives. Consider the 40 ms reset delay duration relative to system startup requirements. Evaluate the 3.3 uA quiescent current impact on overall battery life constraints for the target application design.

Part Context

This part belongs to the MAX6333 series of microprocessor supervisors designed for low-power applications. It serves as a dedicated voltage monitoring solution within the broader portfolio of Maxim Integrated power management ICs. The series focuses on providing reliable reset signals in compact packages for space-constrained electronic designs requiring precise voltage supervision.

Replacement Considerations

MAX6333UR23D3+T offers similar functionality but with a different reset timeout characteristic.
