MAX6315US29D3+TGC1

Supervisors Overview

The MAX6315US29D3+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply voltage with a fixed threshold of 2.9V and asserts an active-low open-drain reset signal if the voltage drops below this level. The device supports a manual reset input for system control. It operates within a supply voltage range of 1V to 5.5V and features a typical reset timeout period of 280ms. The component is available in a compact SOT-143 package, suitable for surface-mount applications.

Supervisors Feature Summary

• Monitors single power-supply voltages from +1.8V to +5.0V
• Asserts reset when supply voltage falls below preset threshold
• Includes edge-triggered, one-shot manual reset function

Supervisors Applications

• Microprocessor system supervision
• Portable electronic devices
• Battery-powered equipment

Supervisors Procurement Notes

Verify the exact suffix against official manufacturer documentation, as variations such as 'T' or '+T' indicate specific tape-and-reel packaging configurations. Confirm that the 'GC1' designation does not imply non-standard electrical parameters or restricted availability. Ensure compliance with RoHS directives and check for lead-free status before procurement.

Supervisors Selection Notes

Select this component for applications requiring precise monitoring of low-voltage rails with minimal quiescent current. The open-drain output allows flexibility in interfacing with various logic families. Consider the manual reset feature if external system control over the reset state is required during debugging or initialization sequences.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits designed for high reliability. These circuits are engineered to ignore fast transients on monitored supplies, preventing false resets. The series offers factory-set thresholds and is optimized for portable applications due to low power consumption and small package size.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6315 family with different threshold voltages if the 2.9V setting is unsuitable. Verify that any substitute maintains the same SOT-143 package and open-drain output configuration to ensure board compatibility.
