Supervisors Procurement Notes

Verify the specific suffix 'MUK47AY' confirms the 4.7V threshold and SOT-23-5 package configuration. Confirm RoHS compliance status as '+T' indicates tape and reel packaging. Check for obsolescence notices or lifecycle status changes from Analog Devices. Ensure compatibility with existing PCB footprint designs for SOT-23-5 components. Validate that the active low push-pull output meets the interface requirements of the target microcontroller.

Supervisors Selection Notes

Select this component when a fixed 4.7V reset threshold is required for single-supply monitoring. Choose the MAX6316 series if watchdog timer integration and manual reset inputs are necessary for system safety. Consider the SOT-23-5 package for space-constrained applications requiring surface-mount technology. Evaluate the 10 µA quiescent current against battery life requirements for portable devices. Ensure the -40°C to +125°C temperature range aligns with the operational environment of the end product.

Supervisors Part Context

The MAX6316MUK47AY-T belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. This family provides multiple combinations of reset outputs and timeout periods. The MAX6316 variant specifically offers watchdog and manual reset features. The family is designed to monitor power supplies and processor activity in digital systems. It supports various threshold voltages from 2.5V to 5V in 100mV increments.

Supervisors Replacement Considerations

Cross-reference with other MAX6316 variants having different threshold voltages if 4.7V is not suitable. Verify pinout compatibility with alternative supervisor ICs in SOT-23-5 packages. Check for functional equivalents from other manufacturers offering similar watchdog and manual reset features.
