MAX6315US46D2-T

Supervisors Overview

The MAX6315US46D2-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features an active-low, open-drain output and includes a manual reset input. The device operates within a supply voltage range up to 5.5V with a threshold of 4.6V. It provides a fixed reset timeout period of 200ms and maintains accuracy within 1.8%. The component supports operation from -40°C to +125°C and consumes only 5µA of quiescent current.

Supervisors Feature Summary

• Provides reliable system reset when supply voltage falls below the preset threshold
• Includes a debounced manual reset input for user-initiated system control
• Features bidirectional compatibility with microprocessors requiring specific reset signaling

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Battery-powered equipment reset management

Supervisors Procurement Notes

Verify exact part number suffixes as distributors may list variants with different tolerance or temperature grades. Confirm RoHS compliance status for the specific batch. Check manufacturer lifecycle status as older Maxim Integrated parts may be discontinued or subject to limited availability. Ensure the SOT-143-4 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed threshold reset is required for single-supply monitoring. The open-drain output allows interfacing with various logic levels. Consider the 200ms timeout duration against system startup requirements. Verify that the 5µA current consumption meets low-power design constraints. Ensure the operating temperature range covers your application environment.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits from Analog Devices/Maxim Integrated. These devices are designed to replace discrete resistor-capacitor networks and external components, offering a compact solution for power supervision. The series typically includes various threshold voltages to accommodate different standard supply rails.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6315 family with matching threshold voltages. Verify if newer revisions from Analog Devices offer equivalent functionality with updated packaging or compliance standards.
