MAX6338PUB+T

Overview

The MAX6338PUB+T is a quad voltage monitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent outputs for monitoring power rails, housed in a compact 10-UMAX package. The device supports an input voltage range from 2.5 V to 5.5 V and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum supply current of 35 µA, reset delay time of less than 1 ms, and threshold accuracy of 2.5%. The thresholds are configurable at -5 V, 3.3 V, 5 V, and adjustable levels.

Feature Summary

• Provides four independent voltage monitoring channels with active low open-drain outputs
• Features configurable threshold voltages including fixed and adjustable options
• Ensures rapid system response with reset timeout duration of less than 1 ms
• Operates efficiently with low quiescent current consumption

Applications

• Multi-rail power supply supervision in embedded systems
• Voltage monitoring for portable electronic devices
• Industrial control system power integrity verification
• Telecommunications equipment power management

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the exact threshold configuration matches the P-subvariant specifications. Ensure compatibility with the 10-UMAX footprint during PCB layout. Check for RoHS compliance documentation as indicated by the '+' suffix. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a limited board area. The adjustable threshold option allows customization for non-standard voltage levels. Consider the low operating current for battery-powered applications. Verify that the open-drain output interface aligns with the downstream logic requirements of the target system design.

Part Context

This part belongs to the MAX6338 family of quad voltage monitors designed for comprehensive power management. It complements other variants like MAX6338CUB+ and MAX6338OUB+ by offering specific threshold configurations. The UMAX package provides a small form factor suitable for space-constrained designs. It serves as a critical component for ensuring system stability against power anomalies.

Replacement Considerations

Direct substitutes include MAX6338CUB+ and MAX6338OUB+ from the same manufacturer. Verify pinout compatibility and threshold voltage alignment before substitution. Cross-reference datasheets to ensure identical package dimensions and electrical characteristics.
