MAX6835VXSD1+T

Supervisors Overview

The MAX6835VXSD1+T is a single-channel supervisory circuit designed for low-voltage power supply monitoring in microprocessor and digital systems. It operates within a supply voltage range of up to 3.6 V and features a fixed reset threshold of 1.575 V. The device provides an active-low, push-pull reset output with a manual reset input capability. It includes a reset timeout delay of 70 µs and consumes a typical operating current of 16 µA. The component is housed in a compact SC-70-4 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable supervision of low-voltage power rails by asserting a reset signal when the supply voltage drops below the preset threshold or upon manual reset activation.
• Features an active-low, push-pull output stage that ensures robust drive capability while maintaining compatibility with standard logic interfaces.
• Integrates a fixed timeout delay to guarantee stable system recovery after power restoration or manual intervention without requiring external timing components.

Supervisors Applications

• Monitoring battery-powered portable electronic devices
• Supervising microcontroller and digital logic power supplies
• Ensuring system reliability in embedded industrial control applications

Supervisors Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure alignment with required electrical parameters and packaging options. Confirm availability status through authorized distributors as this component may be subject to lifecycle restrictions or limited stock conditions. Cross-reference the ordering information to validate compliance with regional regulatory standards and environmental directives relevant to your procurement jurisdiction.

Supervisors Selection Notes

Select this component when a fixed threshold near 1.575 V is required for low-voltage system supervision. Consider the active-low push-pull output characteristic for direct interface with logic gates. Evaluate the 16 µA quiescent current against strict power budget constraints. Ensure the SC-70-4 footprint fits the design layout and verify that the 70 µs timeout meets the minimum stability requirements for the target application.

Supervisors Part Context

This part belongs to the MAX6832–MAX6840 family of ultra-low-voltage SC-70 voltage detectors and microprocessor reset circuits. These devices are engineered to eliminate external components and adjustments for circuits powered between +1.2 V and +1.8 V. The series offers various reset thresholds and timeout periods to provide cost-effective circuit reliability for microprocessor and digital systems.

Supervisors Replacement Considerations

The MAX6835HXSD1+T serves as a functional substitute within the same series, offering identical pinout and functionality but with a different reset threshold voltage of 1.313 V. Verify that the alternative threshold aligns with the specific power rail monitoring requirements before substitution.
