MAX6314US28D2-TG01

Supervisors Overview

The MAX6314US28D2-TG01 is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed threshold voltage of 2.8V and an active-low, bidirectional reset output compatible with interfaces like the 68HC11. The device operates within a supply voltage range up to 5.5V and includes a manual reset input. It offers a reset delay time of 200ms and maintains high accuracy of 1.8%. The component functions without a watchdog timer or battery backup switch, drawing a typical operating current of 5µA. It is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs
• Manual reset input allows for external control of the reset state
• Low quiescent current consumption supports battery-powered applications
• Fixed threshold voltage ensures precise monitoring without external adjustments

Supervisors Applications

• Microcontroller system power supervision
• Digital logic circuit voltage monitoring
• Embedded systems requiring manual reset capability

Supervisors Procurement Notes

Verify the specific suffix D2 indicates the 2.8V threshold variant when sourcing. Confirm the TG01 designation aligns with the required lead-free and RoHS compliance standards for your assembly process. Ensure the SOT-143-4 package matches your PCB footprint design. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and revision status before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy microcontrollers such as the 68HC11 family. Choose this part if a fixed 2.8V threshold is appropriate for the target supply rail. Consider this option for designs prioritizing low standby current and minimal external component count. Verify that the 200ms reset delay meets the timing requirements of the monitored system startup sequence.

Supervisors Part Context

This component belongs to the MAX6314 series of microprocessor supervisory circuits from Maxim Integrated, now part of Analog Devices. The series provides reliable power management solutions for embedded applications. The US28D2 suffix specifically denotes the 2.8V threshold version in the SOT-143 package. These devices are engineered to eliminate external components typically needed for voltage monitoring and reset generation.

Supervisors Replacement Considerations

Compatible substitutes include other MAX6314 variants with different threshold voltages, such as MAX6314US26D3+T for 2.63V applications or MAX6314US33D1-T for 3.3V requirements. Ensure any replacement maintains the SOT-143-4 package and bidirectional output functionality to preserve board compatibility.
