MAX6354SYUK

Overview

The MAX6354SYUK+T is a dual-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +2.7V to +5.5V and features two independent threshold voltages, specifically 3.08V and 4.63V. The device provides a push-pull/totem pole output with an active-low reset signal. It includes a programmable reset timeout with a minimum duration of 100ms. The component is housed in a SOT-23-5 surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Dual independent voltage monitoring channels with factory-programmed thresholds
• Active-low reset output with push-pull/totem pole configuration
• Programmable reset timeout delay starting from 100ms
• Low-power operation suitable for battery-supervised systems

Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered equipment needing low-power monitoring
• Embedded systems with multiple logic power rails
• Industrial control units operating in wide temperature ranges

Procurement Notes

Verify the specific suffix (e.g., SYUK vs LTUK) against official datasheets to confirm exact threshold values and package variations. Ensure compatibility with system voltage levels and thermal requirements. Confirm RoHS compliance status as per current manufacturing revisions. Validate supplier authenticity through authorized distribution channels to prevent counterfeit components.

Selection Notes

Select this component when dual-channel supervision is required in a compact footprint. Compare threshold accuracy and reset timing requirements against alternative supervisors. Consider the push-pull output capability if driving loads directly without external pull-ups. Evaluate power consumption metrics relative to standby current specifications for battery life optimization.

Part Context

The MAX6354 belongs to Maxim Integrated's family of micropower voltage supervisors. These devices are designed to monitor power supply integrity in portable and industrial applications. The series offers various threshold options and packaging styles to accommodate different design constraints while maintaining high accuracy and low quiescent current.

Replacement Considerations

Consult official cross-reference guides for pin-compatible alternatives. Verify that substitute parts match the dual-channel architecture and output drive strength. Ensure replacement components meet the same electrical and thermal specifications.
