MAX6356RWUT+T

Overview

The MAX6356RWUT+T is a triple-voltage microprocessor supervisory circuit in a SOT-23-6 package. It monitors three power supplies with factory-set thresholds of 2.63V, 4.63V, and 4.72V. The device provides an active-low push-pull reset output referenced to VCC1. Key electrical parameters include a maximum supply voltage of 5.5V, a quiescent current of 20µA, and a minimum power-on reset pulse width of 100ms. It operates over an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple voltage rails with precision factory-set thresholds
• Provides active-low push-pull reset output referenced to VCC1
• Includes debounced manual reset input for system control

Applications

• Microprocessor system power supervision
• Multi-rail voltage monitoring in embedded systems
• Battery-powered equipment requiring low standby current

Procurement Notes

Verify the specific suffix RWUT against the official datasheet to confirm the exact threshold voltages and package type. Ensure the component is RoHS compliant if required by your manufacturing standards. Cross-reference the manufacturer part number with Analog Devices or Maxim Integrated documentation to avoid counterfeit parts. Confirm availability through authorized distributors as stock levels vary.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required within a compact footprint. The fixed thresholds eliminate the need for external resistor dividers, simplifying the design. Consider the 20µA supply current for battery-operated applications where low power consumption is critical. Verify that the VCC1 reference level matches the logic requirements of the downstream microprocessor.

Part Context

This part belongs to the MAX635x series of dual and triple-voltage supervisors designed to improve system reliability. These circuits replace discrete components or separate ICs, offering higher accuracy and smaller board space. The series includes variants with watchdog timers and different output configurations to suit various microprocessor architectures.

Replacement Considerations

Check for MAX6356RVUT+T or MAX6356RUUT+T for alternative threshold combinations within the same package. Ensure any substitute maintains the active-low push-pull output referenced to VCC1. Verify pin compatibility and thermal performance before swapping.
