MAX6864UK41D3S+T

Supervisors Overview

The MAX6864UK41D3S+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.1 V with an overvoltage threshold of 4.203 V. The device utilizes an SOT-23-5 surface-mount package and draws a typical operating current of 7 uA. It provides an active low, push-pull output with a reset delay time of 225 ms. The component includes a manual reset function and a watchdog timer but lacks battery backup switching capabilities. It is rated for operation between -40 C and +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside voltage supervision.
• Provides manual reset capability via an external input pin.
• Features an active low, push-pull output driver for direct logic interfacing.

Supervisors Applications

• Embedded systems requiring power supply monitoring
• Microcontroller-based designs needing watchdog functionality
• Portable electronics with limited power budgets

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or special order requirements through authorized distributors. Confirm RoHS compliance details directly with the manufacturer or official datasheet before finalizing procurement plans. Ensure the specific suffix matches the required threshold voltage and package type for your design implementation.

Supervisors Selection Notes

Select this component when a single-supervisor solution with integrated watchdog timing is required in a compact SOT-23-5 package. The 4.1 V threshold suits applications monitoring 3.3 V or similar nominal rails where precise overvoltage detection at 4.203 V is necessary. Consider the 225 ms reset delay and 7 uA quiescent current against system power and timing constraints.

Supervisors Part Context

This part belongs to the MAX6864 series of single nPower supervisors from Analog Devices/Maxim Integrated. The series offers various threshold voltages and reset delays to accommodate different power rail specifications. The UK41 designation indicates the specific 4.1 V threshold variant within this family.
