MAX6316LUK31BX+

Supervisors Overview

The MAX6316LUK31BX+ is a microprocessor supervisory circuit from the MAX6316 family, manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 3.1V and an overvoltage threshold of 3.174V. The device features an active-low push-pull reset output, a manual reset input, and a watchdog timer function. It operates within a supply voltage range up to 5.5V and has a reset delay time of 200ms. The part is housed in a SOT-23-5 surface-mount package and supports an industrial temperature range from -40°C to +125°C. Quiescent current is typically 10µA.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset capabilities for comprehensive system supervision
• Provides factory-trimmed reset threshold accuracy without external components
• Features low quiescent current suitable for power-sensitive applications

Supervisors Applications

• Microprocessor system power monitoring
• Embedded digital systems supervision
• Industrial control unit reset management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance and lead-free specifications match project requirements. Ensure the SOT-23-5 footprint aligns with existing PCB designs. Cross-reference datasheet revisions for any functional updates before finalizing procurement orders.

Supervisors Selection Notes

Select this variant when a 3.1V threshold is required alongside integrated watchdog and manual reset functions. Compare against other MAX6316 series options if different voltage thresholds or output types are needed. Consider the 200ms reset delay and 10µA current consumption relative to system power budgets and timing constraints during initial design phases.

Supervisors Part Context

Part of the MAX6316–MAX6322 family of 5-pin µP supervisory circuits designed to monitor power supplies and processor activity. These devices offer various combinations of reset outputs, watchdog timers, and manual resets. The MAX6316 series provides multiple factory-trimmed threshold voltages ranging from 2.5V to 5V in 100mV increments.

Supervisors Replacement Considerations

Consult official cross-reference lists for compatible alternatives within the MAX6316 series or newer generations such as ADPL62xx. Verify pinout compatibility and electrical parameter equivalence before substitution.
