MAX6425UK46+T

Supervisors Overview

The MAX6425UK46+T is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 4.625 V and provides an active-low, open-drain reset output. The device features a capacitor-adjustable reset timeout delay, allowing for customizable timing characteristics. It operates within a supply voltage range up to 5.5 V and supports an extended industrial temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 or SC-70 footprint, it is designed for space-constrained applications requiring reliable power management supervision.

Supervisors Feature Summary

• Capacitor-adjustable reset timeout delay for flexible timing configuration
• Active-low open-drain reset output compatible with various logic families
• Low-power operation suitable for battery-supplied systems
• Extended industrial temperature range for harsh environment reliability

Supervisors Applications

• Portable electronic devices requiring low standby current
• Industrial control systems needing robust power supervision
• Battery-operated equipment with strict power management requirements
• Embedded systems utilizing microprocessors or DSPs

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging details directly with authorized distributors or the manufacturer. Confirm RoHS compliance status and lead times for the current production lot. Ensure the ordering part number matches the required threshold voltage and package type to avoid integration errors during procurement.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor is insufficient and adjustable reset timing is required. Compare against other MAX6425 variants based on the specific voltage threshold needed. Consider the external capacitor requirement for setting the timeout delay and ensure the open-drain output interface aligns with the target system's pull-up resistor configuration.

Supervisors Part Context

This part belongs to the MAX6425 family of low-power supervisory circuits. The family offers various fixed threshold voltages and adjustable timeout options. The UK46 suffix specifically denotes the 4.625 V threshold variant. These components are widely used in consumer, industrial, and communications equipment for monitoring power rails.

Supervisors Replacement Considerations

Direct substitutes include other MAX6425 variants with different threshold voltages (e.g., MAX6425UK33+T) if the voltage level permits. Verify pinout compatibility and electrical specifications before substituting with generic supervisor ICs.
