MAX6317HUK46CY

Supervisors Overview

The MAX6317HUK46CY+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors a single input with a fixed threshold voltage of 4.6V. The device features an active-high, push-pull reset output and includes manual reset functionality. It operates without a watchdog timer or battery backup switch. The maximum supply voltage is 5.5V, with a typical quiescent current of 3µA. Operating temperatures range from -40°C to +125°C.

Supervisors Feature Summary

• Provides hardware supervision for digital system power supplies
• Integrates manual reset capability for user-initiated control
• Delivers active-high push-pull reset signals

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system reset generation
• Embedded controller supervision

Supervisors Procurement Notes

Verify the suffix 'C' indicates the commercial temperature grade (-40°C to +85°C) rather than industrial, as datasheets typically define this specific letter code. Confirm RoHS compliance status for the '+T' tape-and-reel variant versus the bulk 'Z' version. Check manufacturer lifecycle status for potential obsolescence before finalizing procurement plans.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for systems operating within the specified voltage range. Ensure the 4.6V threshold aligns with the monitored rail's nominal level. Verify that the absence of a watchdog timer meets the application's safety requirements compared to other family members.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices offer various combinations of reset outputs and timeout periods. The MAX6317 specifically provides an active-high output without a watchdog timer, distinguishing it from variants like the MAX6316 which include watchdog functionality.

Supervisors Replacement Considerations

Consider the MAX6319 series for similar supervision without a watchdog but verify output polarity differences. The MAX6316 offers identical pinouts but includes a watchdog timer and uses an active-low output.
