MAX6353UWUK

Overview

The MAX6353UWUK+T is a dual-input voltage supervisory circuit from the MAX6353 series, designed for microprocessor systems. It monitors two independent supply rails with factory-set thresholds of 1.67 V and 2.78 V. The device features active-low push-pull reset outputs referenced to VCC1, ensuring system stability during power fluctuations. It operates within an extended temperature range of -40°C to +85°C and consumes only 20 µA of supply current. The unit is housed in a compact SOT-23-5 package.

Feature Summary

• Monitors two distinct input voltages against preset thresholds
• Provides active-low push-pull reset signals referenced to VCC1
• Includes debounced manual reset input functionality
• Operates with ultra-low 20 µA supply current consumption

Applications

• Microprocessor (µP) system supervision
• Dual-voltage power supply monitoring
• Embedded controller reset management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check current availability as this part may be subject to limited supply or discontinuation. Ensure packaging type matches design requirements. Validate threshold voltage specifications against application needs before procurement.

Selection Notes

Select this component when dual-rail supervision is required without watchdog timer functionality. Suitable for designs needing precise factory-set thresholds at 1.67 V and 2.78 V. Ideal for space-constrained applications due to the SOT-23-5 package. Consider if low quiescent current is critical for battery-operated systems requiring extended operational life.

Part Context

Part of the MAX635x family of dual/triple-voltage supervisors. Shares common interface characteristics with MAX6351–MAX6360 series devices. Designed to replace discrete monitoring components for improved reliability. Manufactured by Analog Devices under the Maxim Integrated brand. Offers precision monitoring for standard logic supply voltages.

Replacement Considerations

Direct substitutes include other MAX6353 variants with different threshold options. Cross-reference with MAX6354 series for similar functionality but different output referencing. Verify pin compatibility when replacing with generic equivalents. Ensure thermal performance matches original design constraints.
