MAX6725KAYHD3

Supervisors Overview

The MAX6725KAYHD3+T is a triple ultra-low-power voltage supervisor in an SOT-23-8 package. It monitors three independent input voltages with thresholds ranging from 900 mV to 5 V. The device features a manual reset input, a watchdog timer, and active high/low or open-drain outputs. Operating supply current is 15 µA. Maximum supply voltage is 5.5 V. Reset delay times vary by variant, including 280 ms and 1.12 s. Overvoltage thresholds are adjustable or fixed at specific levels such as 1.71 V, 1.14 V, 3.15 V, or 2.25 V. Power dissipation is rated at 714 mW. Operating temperature range is -40°C to +125°C.

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance and REACH restrictions before integration. Check datasheet revision history for parameter updates. Ensure thermal management meets the 714 mW dissipation limit. Validate pinout compatibility with existing PCB layouts.

Supervisors Selection Notes

Evaluate threshold voltage ranges against target supply rails. Compare reset delay times with system startup requirements. Consider output drive capabilities for load interfacing. Assess thermal performance within the specified operating temperature range. Verify package footprint alignment with manufacturing constraints.

Supervisors Part Context

Part of the MAX6725 series offering multi-channel supervision. Shares family features like low power and compact packaging. Differs from MAX6735 in specific threshold configurations and reset timing characteristics. Designed for applications requiring reliable power monitoring in space-constrained environments.

Supervisors Replacement Considerations

MAX6725AKAYHD3+T serves as a direct functional substitute within the same series. Both share identical package dimensions and core supervisory functions. Verify specific overvoltage threshold values match application requirements. Confirm reset delay specifications align with system timing needs.
