MAX6328UR22+T

Supervisors Overview

The MAX6328UR22+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for power supply support. It features an open-drain or open-collector output with a low-active reset signal. The device monitors a single voltage channel with a fixed threshold of 2.2V and provides a minimum reset timeout of 100ms. It operates within a temperature range of -40°C to 85°C and is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for monitored voltage channels
• Features an open-drain or open-collector output configuration
• Delivers a guaranteed minimum reset timeout duration

Supervisors Applications

• Embedded system power management
• Microcontroller reset supervision
• Portable electronic device power monitoring

Supervisors Procurement Notes

Verify the specific suffix UR22 to confirm the 2.2V threshold setting, as variations exist within the MAX6328 family. Ensure compatibility with the target operating temperature range of -40°C to 85°C. Confirm that the open-drain output architecture aligns with the pull-up requirements of the connected logic interface. Check RoHS compliance status for environmental regulations.

Supervisors Selection Notes

Select this component when a fixed 2.2V threshold is required for single-channel voltage monitoring. The open-drain output necessitates an external pull-up resistor, which allows flexibility in interfacing with various logic voltage levels. Consider the SOT-23-3 package size for space-constrained designs requiring surface-mount assembly.

Supervisors Part Context

This part belongs to the MAX6328 series of ultra-low-power reset circuits from Maxim Integrated. The series offers various fixed voltage thresholds to accommodate different supply rails. The UR22 variant specifically targets applications requiring a 2.2V detection level, distinguishing it from other threshold options in the same product line.

Supervisors Replacement Considerations

Cross-reference with other MAX6328 variants such as MAX6328UR28+T or MAX6328UR30+T if different voltage thresholds are acceptable. Verify pinout compatibility before substitution.
