MAX6320PUK46BY+T

Supervisors Overview

The MAX6320PUK46BY+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors a single voltage input with a threshold of 4.63V and an overvoltage threshold of 4.699V. The device features an active low, open-drain reset output with a 20ms minimum timeout. It includes a watchdog timer and manual reset capability. Operating current is 10uA, with a maximum supply voltage of 5.5V. The operating temperature range spans from -40°C to +125°C.

Supervisors Feature Summary

• Integrates power supply monitoring with watchdog timer and manual reset functionality for comprehensive system protection.
• Provides flexible design options through configurable push/pull, open-drain, and bidirectional reset outputs.
• Offers factory-trimmed reset threshold voltages with high accuracy for precise supervision requirements.

Supervisors Applications

• Microprocessor activity monitoring in digital systems
• Power supply supervision for embedded controllers
• Watchdog timer implementation for fault recovery

Supervisors Procurement Notes

Verify the specific suffix 'BY' against the manufacturer's datasheet to confirm the exact reset threshold voltage and output configuration. Ensure the ordering increment requirements are met, as standard versions may require minimum order quantities. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for systems operating up to 5.5V. Consider the open-drain output type if level shifting or wired-OR configurations are needed. Evaluate the 10uA quiescent current against battery life requirements. Compare alternative threshold voltages within the MAX6316-MAX6322 family if the 4.63V setting does not match the target rail voltage precisely.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. The family provides various combinations of reset outputs, watchdog timers, and manual resets. These devices are designed to monitor power supplies and processor activity, offering multiple threshold voltages and timeout periods in a miniature SOT-23 package for space-constrained applications.

Supervisors Replacement Considerations

Consider MAX6320PUK46CY+T for similar threshold but different output characteristics. Check MAX6316 series variants for comparable functionality with potentially different reset timeouts or output types. Verify pinout compatibility and electrical specifications before substitution.
