MAX6315US46D2+

Supervisors Overview

The MAX6315US46D2+ 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 output that asserts when the supply voltage falls below a preset threshold of 4.6V or when a manual reset input is triggered. The device operates within a supply voltage range up to 5.5V and includes a fixed reset timeout period of 200ms. It is housed in a compact SOT-143-4 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset by monitoring supply voltage against a fixed threshold
• Includes a debounced manual reset input for user-initiated system control
• Features an active-low open-drain output compatible with various logic families
• Designed for low-power applications with minimal quiescent current consumption

Supervisors Applications

• Microprocessor power supply supervision
• Digital system voltage monitoring
• Battery-powered equipment reset circuits
• Embedded controller power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead times directly with suppliers. Check for obsolescence notices as this series may have limited availability. Ensure storage conditions meet moisture sensitivity level requirements before assembly.

Supervisors Selection Notes

Select this part when a fixed 4.6V threshold is required for system supervision. Consider the open-drain output configuration for interfacing with different logic voltages. Verify that the 200ms reset delay meets system timing requirements. Evaluate thermal performance within the specified operating temperature range.

Supervisors Part Context

This component belongs to the MAX6315 family of uP reset circuits from Maxim Integrated. These devices are engineered for cost-effective power supervision without external adjustments. The series offers various threshold options to accommodate different supply rail requirements while maintaining consistent low-power characteristics and compact packaging solutions.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6315 series with adjusted thresholds. Verify functional equivalence for supervisory circuits requiring manual reset inputs. Confirm package compatibility with existing PCB footprints.
