MAX6335US18D3-T

Supervisors Overview

The MAX6335US18D3-T is a microprocessor supervisory circuit designed for 1.8V to 3.3V digital systems. It features an active-high push/pull reset output and monitors the VCC supply voltage. The device asserts a reset signal when VCC declines below a preset threshold or upon manual reset assertion. It operates with an ultra-low supply voltage of 0.7V and consumes only 3.3µA of supply current. The component is housed in a compact 4-pin SOT-143 package, suitable for space-critical applications.

Supervisors Feature Summary

• Active-high push/pull reset output configuration
• Debounced manual-reset input capability
• Ultra-low operating supply voltage down to 0.7V
• Low power consumption of 3.3µA

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Space-critical embedded designs

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact reset threshold voltage, as variations exist within the MAX6335 series. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may be restricted. Ensure the active-high output requirement matches the target system logic before procurement.

Supervisors Selection Notes

Select this component when an active-high reset signal is required for low-voltage digital systems. Compare against MAX6336 and MAX6337 variants if active-low outputs are acceptable, as they share similar electrical characteristics but differ in output stage configuration. Verify that the 0.7V minimum operating voltage meets the system's brown-out requirements.

Supervisors Part Context

This part belongs to the MAX6335/MAX6336/MAX6337 family of ultra-low-voltage, low-power µP reset circuits manufactured by Maxim Integrated, now part of Analog Devices. These devices eliminate external components by integrating precision comparators and timeout timers into a small 4-pin SOT-143 package, simplifying design for portable and battery-operated electronics.

Supervisors Replacement Considerations

MAX6335US19D3-T: Different threshold voltage. MAX6336US18D3-T: Active-low output. MAX6337US18D3-T: Open-drain output.
