MAX6468XS26D1

Overview

The MAX6468XS26D1+T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5 V and features a maximum power supply voltage of 5.5 V. The device provides an active low, push-pull output with a manual reset capability and a fixed reset delay time of 225 ms. It monitors a single input channel without watchdog timer or battery backup switch functions. The component draws a typical operating supply current of 7 uA and includes overvoltage threshold detection at 2.603 V. It is housed in a compact SC-70-4L surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides precise voltage supervision for microprocessor systems with manual reset functionality
• Features low quiescent current consumption suitable for battery-powered applications
• Delivers active low push-pull output signal for direct interface with digital logic

Applications

• Microprocessor (MPU) supervisory reset circuits
• Battery-operated electronic devices requiring voltage monitoring
• Portable instrumentation systems

Procurement Notes

Verify the specific suffix D1 against official datasheets to confirm the exact overvoltage threshold value, as variations exist within the MAX6468 family. Confirm RoHS compliance status through manufacturer documentation. Check current availability status as some variants may be discontinued or subject to limited supply constraints. Ensure the SC-70-4L package matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when a single-channel voltage supervisor with manual reset is required. The 7 uA supply current makes it suitable for low-power designs. Verify that the 225 ms reset delay meets system timing requirements. Ensure the operating voltage range covers the minimum and maximum levels of the monitored rail. Consider the SC-70-4L package size constraints during layout design.

Part Context

The MAX6468 series consists of micropower voltage supervisors designed for portable electronics. This specific variant belongs to the Maxim Integrated line, now part of Analog Devices. The series offers various threshold voltages and package options to accommodate different system architectures. The MAX6468 family is known for its reliability in maintaining system stability under varying power conditions.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the SC-70-4L package and 7 uA current specifications. Verify identical reset delay and output polarity characteristics.
