MAX6352SYUK

Overview

The MAX6352SYUK is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two distinct voltage levels, specified as 2.19V and 2.93V thresholds in available documentation. The device features an active-low reset output with a typical timeout of 100ms and a delay time of 280ms. It operates within a supply voltage range up to 5.5V and supports temperatures from -40°C to +85°C. The component utilizes an Open Drain or Open Collector output configuration and is housed in a SOT-23-5 package.

Feature Summary

• Dual-channel voltage monitoring for independent supervision of multiple power rails
• Active-low reset signal generation upon detection of out-of-range voltages
• Open Drain or Open Collector output interface for flexible system integration

Applications

• Monitoring primary and backup power supplies in embedded systems
• Ensuring correct startup and shutdown sequences in microprocessor-based designs
• Providing supervision for dual-voltage logic interfaces

Procurement Notes

Verify the specific suffix (e.g., SYUK) against the manufacturer's current datasheet to confirm pinout and threshold accuracy. Ensure RoHS compliance status matches project requirements. Confirm package type is SOT-23-5. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Check for lead-free designation if required by regulatory standards.

Selection Notes

Select this component when dual voltage supervision is required in a compact form factor. The fixed thresholds of 2.19V and 2.93V suit applications needing specific low-voltage monitoring points. Consider the active-low output polarity and open-drain nature for compatibility with downstream logic. Evaluate thermal performance within the -40°C to +85°C operating range for environmental suitability.

Part Context

The MAX6352 belongs to the MAX6352S series of dual/triple-voltage microprocessor supervisory circuits. These devices are designed to provide reliable reset signals for complex digital systems. The SYUK variant specifically denotes the SOT-23-5 package option, offering a small footprint suitable for space-constrained portable and industrial electronics.

Replacement Considerations

Consult official substitution guides for equivalent dual-supervisor ICs with compatible voltage thresholds and package types. Verify that alternative parts support the same active-low reset polarity and open-drain output configuration. Ensure thermal and electrical specifications meet or exceed the original design requirements.
