MAX6388XS40D4-T

Supervisors Overview

The MAX6388XS40D4-T is a dual-channel voltage supervisory circuit manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5 V and features an adjustable overvoltage threshold set at 4.02 V. The device provides two monitored inputs with active-high, push-pull outputs. Key electrical parameters include a reset delay time of 1.68 s, a typical operating supply current of 7 uA, and a maximum accuracy of 2.5%. It supports a maximum power dissipation of 245 mW and functions reliably across an extended temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent voltage supervision
• Active-high push-pull output configuration for direct logic interfacing
• Adjustable overvoltage threshold detection mechanism
• Low-power operation suitable for battery-supplied systems

Supervisors Applications

• Microprocessor (µP) power supply supervision
• Battery backup system monitoring
• Portable electronic device power management
• Industrial control board voltage tracking

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications against the official datasheet. Ensure the ordering suffix matches the required tape-and-reel configuration. Cross-reference the specific threshold voltage setting with design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when dual-input voltage supervision with active-high outputs is required. Verify that the adjustable overvoltage threshold aligns with system protection limits. Consider the 1.68 s reset delay duration for timing-sensitive applications. Evaluate the 7 uA supply current consumption against total system power budgets. Confirm SC-70-4 package compatibility with PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6388 series of microprocessor supervisory circuits designed for low-voltage, low-power applications. The series offers various threshold voltages and timeout delays to accommodate different system requirements. The MAX6388 variant specifically provides dual-channel monitoring in compact surface-mount packages, distinguishing it from single-channel counterparts in the broader product family.
