MAX6316LUK46BX+

Supervisors Overview

The MAX6316LUK46BX+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold voltage of 4.6V. The device includes a watchdog timer and manual reset input, housed in a compact SOT-23-5 package. It supports an operating temperature range from -40°C to +125°C and consumes low quiescent current.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring processor activity
• Includes a manual reset input for system control
• Provides factory-trimmed fixed reset threshold voltages
• Offers multiple output configurations including push-pull and open-drain

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor activity supervision
• Portable electronic devices requiring low power consumption
• Embedded systems with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix 'BX' against official Analog Devices documentation to confirm exact threshold tolerance and package variant. Ensure compatibility with existing board layouts for SOT-23-5 footprint. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference lead times and availability directly with authorized distributors.

Supervisors Selection Notes

Select this component when a fixed 4.6V reset threshold is required for single-supply monitoring. Consider the integrated watchdog and manual reset features if system reliability depends on active processor supervision. Evaluate the SOT-23-5 package size constraints against available PCB space. Compare performance metrics such as reset delay time and quiescent current against alternative supervisory circuits.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity in digital systems. The family offers various combinations of reset outputs and thresholds, providing flexibility for different application requirements while maintaining a consistent pinout and package style.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6316 series with different threshold voltages or output types. Verify pin-to-pin compatibility with other SOT-23-5 supervisory ICs from Analog Devices or competitors. Ensure functional equivalence regarding watchdog timeout periods and manual reset logic levels before substitution.
