MAX6320PUK46BX+T

Supervisors Overview

The MAX6320PUK46BX+T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.6V and an active-low push-pull reset output. The device includes a manual reset input and a watchdog timer with selectable timeout periods. It operates within a supply voltage range up to 5.5V and functions across an extended temperature range of -40°C to +125°C. Packaged in a compact SOT-23-5 surface-mount case, it draws low quiescent current.

Supervisors Feature Summary

• Integrated manual reset input for system control
• Watchdog timer functionality for processor monitoring
• Active-low push-pull reset output stage
• Extended industrial temperature operation capability

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix BX against official Analog Devices documentation to confirm the exact reset threshold voltage and timeout configuration. Confirm RoHS compliance status for the specific manufacturing batch. Check current production status as availability may vary by region. Ensure the SOT-23-5 package matches the target PCB footprint requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supply monitoring. The inclusion of both manual reset and watchdog features makes it suitable for complex digital systems requiring robust fault handling. Compare quiescent current specifications against other family members if battery life is critical. Verify that the push-pull output drive capability meets the load requirements of the connected microprocessor reset pin.

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 MAX6320 variant specifically provides an active-low push-pull output. The family allows for flexible design integration through factory-trimmed thresholds ranging from 2.5V to 5V.

Supervisors Replacement Considerations

Other parts in the MAX6316–MAX6322 family may serve as substitutes if different output stages or thresholds are acceptable. Verify pin compatibility and electrical characteristics before substitution.
