MAX6315US46D4+T

Supervisors Overview

The MAX6315US46D4+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.63 V. The device provides an active low, open-drain output with a manual reset capability and a reset delay time of 200 ms. It consumes only 5 uA of operating current and maintains accuracy within 1.8%. The component is housed in a compact SOT-143-4 package and supports surface mount installation. It functions reliably across a wide temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 4.63 V threshold for system supervision
• Features ultra-low power consumption of 5 uA suitable for battery-operated applications
• Includes manual reset functionality with a guaranteed 200 ms reset delay time
• Delivers an active low open-drain output signal compatible with standard logic interfaces

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-powered systems needing efficient power management
• Embedded controllers requiring reliable reset signals during power transitions
• Industrial equipment operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix D4 against official Analog Devices documentation to confirm the 4.63 V threshold specification. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for end-of-life notices as similar MAX6315 variants may be obsolete. Ensure the SOT-143-4 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-channel voltage monitoring. Consider the 5 uA quiescent current if power efficiency is critical. The open-drain output requires an external pull-up resistor. Verify that the 200 ms delay meets your system's startup timing constraints. Ensure the operating temperature range covers your application environment.

Supervisors Part Context

This part belongs to the MAX6315 series of microprocessor reset circuits. It is designed for applications requiring simple, low-cost voltage supervision. The series offers various threshold voltages and packages. Analog Devices acquired Maxim Integrated, unifying these product lines under one manufacturer. The US46 suffix specifically denotes the 4.63 V threshold variant in the SOT-143 package.

Supervisors Replacement Considerations

Check Analog Devices official documentation for direct pin-to-pin replacements within the MAX6315 family. Variants like MAX6315US45D3+T offer different thresholds but share the same package. Verify electrical specifications match before substitution. No other manufacturers are confirmed as direct equivalents in the provided data.
