MAX6740XKZWD3+T

Supervisors Overview

The MAX6740XKZWD3+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features three monitored inputs with threshold voltages ranging from 1.8 V to 5 V and 900 mV to 3.3 V. The device provides an active low, open-drain output and includes manual reset functionality without a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V and has a reset delay time of 225 ms. The component is housed in an SC-70-5 package and supports surface mount installation.

Supervisors Feature Summary

• Monitors multiple voltage rails simultaneously for system integrity
• Provides manual reset capability for controlled system recovery
• Operates with low power consumption suitable for portable applications

Supervisors Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered systems needing low quiescent current monitoring
• Embedded controllers requiring manual reset input integration

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance and lead times as supply may be restricted. Ensure packaging specifications match design requirements before finalizing procurement orders for this specific part number.

Supervisors Selection Notes

Select this component when multiple voltage lines require simultaneous supervision within a compact footprint. Consider the open-drain output configuration for compatibility with existing logic levels. Evaluate the manual reset feature against automatic reset requirements for the target application environment.

Supervisors Part Context

This part belongs to the MAX6740 series of low-power supervisors designed for space-constrained designs. It integrates voltage monitoring and reset generation in a small SC-70-5 package. The series targets applications where power efficiency and board real estate are critical constraints.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer family. Verify electrical parameter equivalence including threshold voltages and output drive capabilities before substitution.
