MAX6352SYUK+T

Overview

The MAX6352SYUK+T is a dual-channel voltage supervisor IC from Analog Devices, housed in an SOT-23-5 package. It monitors two supply voltages with thresholds of 2.19 V and 2.93 V. The device operates within a supply range of 1 V to 5.5 V and features an active-low open-drain reset output. Key timing parameters include a reset timeout of 100 ms and a reset delay time of 280 ms. It supports battery backup switching and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel voltage monitoring for independent power rail supervision
• Active-low open-drain reset output for flexible logic interfacing
• Integrated reset timeout and delay timers for stable system recovery

Applications

• Microprocessor (MPU) power supply supervision
• Portable electronic devices requiring low-voltage monitoring
• Battery-powered systems needing reliable power management

Procurement Notes

Verify the specific threshold voltages (2.19 V and 2.93 V) against your design requirements before procurement. Confirm the SOT-23-5 package compatibility with your PCB footprint. Ensure the operating temperature range meets your environmental specifications. Check for lead-free compliance indicated by the '+T' suffix. Validate that the active-low output polarity matches your controller's input expectations.

Selection Notes

Select this component when dual-rail supervision is required in a compact form factor. The SOT-23-5 package offers space efficiency for portable designs. Consider the 100 ms timeout duration for application-specific reset stability needs. The wide supply voltage range accommodates various single-supply configurations. Verify that the open-drain output can be properly pulled up to the monitored voltage level.

Part Context

This part belongs to the MAX6352 family of supervisory circuits designed for monitoring multiple voltage rails. It integrates essential power management functions into a small surface-mount package. The series is optimized for applications requiring precise voltage detection and controlled reset generation. Analog Devices provides comprehensive documentation for integration support.
