MAX6316LUK29AX-T

Supervisors Overview

The MAX6316LUK29AX-T is a microprocessor supervisory circuit from the MAX6316 family, designed to monitor power supplies and processor activity in digital systems. It features a fixed reset threshold voltage of 2.9V with an active-low push-pull output. The device integrates a watchdog timer and a manual reset input for enhanced system reliability. It operates within a supply voltage range up to 5.5V and consumes only 10µA of quiescent current. The component is housed in a compact SOT-23-5 package and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer and manual reset input for comprehensive system supervision
• Features an active-low push-pull reset output stage
• Designed to ignore fast negative transients on VCC
• Ensures valid resets down to 1V supply voltage

Supervisors Applications

• Monitoring power supplies in embedded digital systems
• Supervising microprocessor activity in industrial controllers
• Providing reset signals for battery-powered devices

Supervisors Procurement Notes

Verify the exact suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'L' prefix denotes low-power operation characteristics. Ensure the 'U' suffix matches the required 2.9V threshold specification. Validate the 'K' suffix for the specific package variant. Check manufacturer documentation for current production status as this series may have limited availability.

Supervisors Selection Notes

Select this part when a fixed 2.9V threshold is required for single-supply monitoring. Choose the active-low push-pull output if direct logic interfacing is needed without external pull-ups. Consider the integrated watchdog feature if software lockup protection is necessary. Verify that the 10µA quiescent current meets low-power design constraints.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices offer various combinations of reset outputs, watchdog timers, and manual reset inputs. The family provides 26 factory-trimmed threshold voltages ranging from 2.5V to 5V in 100mV increments, allowing precise selection for different rail voltages.

Supervisors Replacement Considerations

Check for other MAX6316 variants with different thresholds or output types. Verify compatibility with MAX6318 or MAX6319 families if bidirectional or open-drain outputs are acceptable alternatives.
