MAX6741XKRVD3+

Supervisors Overview

The MAX6741XKRVD3+T is a low-power dual- and triple-voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.0 V to 5.5 V and features an SC-70-5 package. The device monitors two input channels with fixed thresholds of 1.11 V and 2.313 V, providing active-low open-drain outputs. It includes a manual reset function, a 225 ms reset delay, and maintains accuracy within 3%. Operating current ranges from 5 µA to 10 µA, supporting extended temperature operation from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring with fixed threshold levels for precise power supervision

Supervisors Procurement Notes

Verify the complete part number suffix, as variations such as KRVD3 indicate specific package or tape-and-reel configurations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure availability checks are performed directly with authorized distributors, as stock levels fluctuate. Validate that the selected variant matches the required pinout and electrical specifications for the target application design.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required alongside manual reset functionality. The fixed threshold voltages eliminate the need for external resistor networks, simplifying board layout. Consider the SC-70-5 package dimensions for footprint compatibility. Evaluate the 3% accuracy specification against system tolerance requirements. Verify that the open-drain output configuration aligns with the downstream logic interface capabilities.

Supervisors Part Context

This component belongs to the MAX6741 series of supervisory circuits designed for low-power applications. It complements other Maxim Integrated voltage supervisors by offering dual-channel monitoring in a minimal footprint. The series supports various threshold combinations to accommodate different standard voltage rails commonly found in portable electronics and embedded systems.

Supervisors Replacement Considerations

Consult the official datasheet for cross-reference information regarding compatible alternatives within the MAX6741 family or similar dual-supervisor products. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
