MAX6314US26D3+T

Supervisors Overview

The MAX6314US26D3+T is a low-power CMOS microprocessor supervisory circuit designed for monitoring power supplies in digital systems. It features a bidirectional RESET output compatible with inputs like the 68HC11. The device monitors a single input with a fixed threshold voltage of 2.63 V and an overvoltage threshold of 2.68 V. It operates within a supply voltage range up to 5.5 V, consuming only 5 µA of quiescent current. The reset delay time is 200 ms, with accuracy of 1.8%. It includes a manual reset input and functions within a temperature range of -40°C to +85°C.

Supervisors Procurement Notes

Verify the exact suffix D3 corresponds to the 2.63 V threshold and SOT-143-4 package configuration. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the component matches the specific pinout and electrical characteristics required for your bidirectional interface design before finalizing procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for microprocessors such as the 68HC11. It is suitable for applications needing a fixed 2.63 V threshold with a 200 ms timeout. Consider the SOT-143-4 package size and 5 µA current draw for space-constrained or battery-powered designs operating within the specified temperature range.

Supervisors Part Context

The MAX6314 belongs to the Maxim Integrated line of low-power CMOS microprocessor supervisory circuits. This series focuses on providing reliable power management without external components. The US26D3 variant specifically addresses systems requiring bidirectional communication capabilities for reset signals, distinguishing it from standard open-drain outputs found in other supervisory ICs.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional RESET output allows the MAX6314 to be directly connected to microprocessors that utilize bidirectional reset pins, such as the 68HC11, facilitating seamless integration without additional level-shifting components.

Does the MAX6314 include a watchdog timer?

No, the MAX6314 does not include a built-in watchdog timer. It functions solely as a voltage supervisor with a manual reset input.
