MAX6315US46D2+T

Supervisors Overview

The MAX6315US46D2+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features an active-low, open-drain reset output with a fixed threshold voltage of 4.6V. The device includes a manual reset input for system control and operates within a supply voltage range up to 5.5V. It provides a typical reset timeout period of 200ms and maintains accuracy within 1.8%. The component supports surface-mount installation in a compact SOT-143-4 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable power-supply monitoring with a fixed threshold voltage for consistent system supervision.
• Features an active-low, open-drain reset output compatible with standard logic interfaces.
• Includes a debounced manual reset input for direct user or external control intervention.
• Operates with ultra-low quiescent current to minimize power consumption in battery-powered applications.

Supervisors Applications

• Microprocessor and digital system power supply monitoring
• Battery-operated electronic devices requiring low standby current
• Portable instrumentation and handheld equipment
• Industrial control systems operating in extended temperature environments

Supervisors Procurement Notes

Verify the exact suffix D2 against official Analog Devices documentation to confirm the specific threshold voltage variant, as suffixes define electrical parameters. Confirm RoHS compliance status via the manufacturer's certificate. Check current lifecycle status, as Maxim Integrated products may face obsolescence. Ensure the SOT-143-4 package availability matches your manufacturing requirements. Validate that the open-drain output configuration aligns with your target load impedance.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-channel voltage supervision. The open-drain output necessitates an external pull-up resistor; ensure the resistor value suits your system's speed and voltage levels. Verify that the 200ms timeout meets your processor's startup timing constraints. Consider the SOT-143-4 footprint if space is limited. Compare against the MAX6314 series if bidirectional output compatibility with specific microcontrollers like the 68HC11 is needed instead of open-drain.

Supervisors Part Context

This part belongs to the MAX6315 family of supervisory circuits from Analog Devices (Maxim Integrated). The family offers various threshold voltages and output configurations. The US46 designation indicates the specific 4.6V threshold version. These circuits are designed to replace discrete supervisor components, reducing board space and design complexity while improving reliability through integrated precision references and timers.

Supervisors Replacement Considerations

Check for MAX6315US46D3+T if a different timeout characteristic is acceptable. Verify MAX6314US46D2+T if bidirectional output is required instead of open-drain. Consult Analog Devices for current recommended replacements if this specific suffix is discontinued.
