MAX6388XS23D4-T

Supervisors Overview

The MAX6388XS23D4-T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two power-supply inputs within the +1.8V to +5.0V range, featuring an active-high push-pull reset output. The device operates with a maximum supply voltage of 5.5V and consumes only 7µA of quiescent current. It provides a fixed reset delay time of 280ms and maintains accuracy within 2.5%. The component supports an extended industrial temperature range from -40°C to +125°C and is housed in a compact SC-70-4 surface-mount package.

Supervisors Feature Summary

• Dual-input voltage monitoring for independent power rails
• Active-high push-pull reset output configuration
• Ultra-low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring low standby current
• Embedded systems with multiple voltage domains
• Industrial control units operating in extreme temperatures

Supervisors Procurement Notes

Verify the specific suffix D4 against official datasheets to confirm the exact reset timeout value, as variations exist within the series. Confirm RoHS compliance status (+T designation) and lead-free requirements prior to ordering. Check manufacturer lifecycle status for obsolescence warnings. Ensure the SC-70-4 footprint matches the target PCB layout constraints.

Supervisors Selection Notes

Select this component when dual-channel supervision with active-high logic is required. Compare the 280ms delay against system startup timing requirements. Evaluate the 7µA current draw against total system power budgets. Verify that the 5.5V absolute maximum rating exceeds the highest expected supply rail voltage under all transient conditions.

Supervisors Part Context

This part belongs to the MAX6388XS family of low-voltage, low-power reset circuits. It shares architectural similarities with single-channel variants like the MAX6388XS23D3+T but adds a second monitored input. The series is designed for applications where space and power efficiency are critical constraints.

Supervisors Replacement Considerations

Consider MAX6388XS23D3+T for single-channel applications. Verify pinout compatibility before substituting with other SC-70-4 supervisory ICs.
