MAX6316MUK47BY

Supervisors Overview

The MAX6316MUK47BY is a microprocessor supervisory circuit from the MAX6316 family, manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies and processor activity in digital systems. The device features a fixed reset threshold voltage of 4.7V, an active-low push-pull reset output, and a manual reset input. It includes a watchdog timer with a typical timeout period of 1.4 seconds. Operating on a single supply voltage up to 5.5V, it consumes only 10µA of quiescent current. The component operates within a temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring microprocessor activity alongside power supply supervision
• Provides a manual reset input for external system control
• Features low quiescent current consumption suitable for battery-powered applications
• Offers factory-trimmed reset threshold voltages for precise monitoring

Supervisors Applications

• Microprocessor system power management
• Battery-operated electronic devices
• Industrial control systems requiring watchdog functionality
• Portable instrumentation

Supervisors Procurement Notes

Verify the specific suffix 'BY' against official Analog Devices documentation to confirm pinout and electrical characteristics, as suffixes often denote specific package or temperature variants. Confirm RoHS compliance status through the manufacturer's current datasheet. Check production status as some Maxim Integrated parts may have limited availability or obsolescence notices. Ensure the 4.7V threshold matches the target supply rail requirements.

Supervisors Selection Notes

Select this part when a fixed 4.7V reset threshold is required for systems powered between 2.5V and 5.5V. The integrated watchdog timer makes it suitable for applications needing automatic recovery from software hangs. The SOT-23-5 package is ideal for space-constrained designs. Compare against other MAX6316 variants if different thresholds or output types are needed.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity. The family offers various combinations of reset outputs and features like watchdog timers and manual resets. They are available in multiple factory-trimmed threshold voltages ranging from 2.5V to 5V.

Supervisors Replacement Considerations

Other MAX6316 variants with different threshold voltages (e.g., MAX6316MUK48) may be pin-compatible but require verification of the reset threshold. ADM6316 series devices from Analog Devices offer similar functionality but may differ in electrical specifications or package options.
