MAX6314US26D2-T

Supervisors Overview

The MAX6314US26D2-T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supply voltages in microprocessor and digital systems, featuring a bidirectional reset output compatible with devices like the 68HC11. The device includes a debounced manual reset input and operates within a supply voltage range of up to 5.5V. Key electrical parameters include a threshold voltage of 2.6V, a reset delay time of 280ms, and a quiescent current of 5µA. It functions reliably across an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional inputs
• Debounced manual reset input for user-initiated system resets
• Low-power CMOS design suitable for battery-operated applications

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring manual reset functionality

Supervisors Procurement Notes

Verify the exact suffix D2 against official datasheets to confirm the specific threshold voltage variant, as suffixes denote different factory-set trip points. Confirm RoHS compliance status (+T vs non-plus variants) and package availability (SOT-143-4). Check for obsolescence or lifecycle changes directly with Analog Devices, as distribution listings may not reflect current manufacturing status.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for legacy or specific microcontroller architectures. Ensure the 2.6V threshold matches the target supply rail's minimum operating voltage. Consider the 280ms timeout period relative to the system's startup requirements. Verify that the SOT-143-4 package fits the PCB layout constraints.

Supervisors Part Context

The MAX6314 belongs to a family of low-power µP reset circuits designed to eliminate external components. Unlike standard push-pull outputs, its bidirectional nature simplifies integration with specific processor families. The US26 designation indicates a fixed 2.6V threshold, distinguishing it from other variants in the series with different trip points.

Supervisors Replacement Considerations

Cross-reference with MAX6314USxxD2-T variants for different voltage thresholds. For non-bidirectional needs, consider MAX638x series parts. Verify pinout compatibility if substituting with other SOT-143-4 supervisors.
