MAX6495ATT/V+

Specialized ICS Overview

The MAX6495ATT/V+ is a high-voltage overvoltage-protection controller designed for automotive and industrial transient systems. It monitors input voltage and controls an external nMOSFET to isolate the load during overvoltage conditions or limit output voltage in limiter mode. The device operates within a supply voltage range of +5.5V to +72V, featuring an integrated charge pump that provides a typical 10V gate-to-source enhancement voltage. It includes adjustable overvoltage thresholds via the OVSET pin, fast gate shutoff with 100mA sink capability, and thermal shutdown protection. Qualified under AEC-Q100 standards, it functions reliably across a temperature range of -40°C to +125°C.

Specialized ICS Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package integrity for the 6-TDFN (3x3mm) configuration. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Cross-reference ordering information against official Maxim Integrated datasheets to validate suffix designations.

Specialized ICS Selection Notes

Select this controller when system protection requires handling transients up to 72V. Pair with an external nMOSFET rated for the specific application current and voltage requirements. Utilize the OVSET pin resistive divider to set precise overvoltage trip points. Consider the MAX6496 variant if reverse-battery protection using a pMOSFET is required instead.

Specialized ICS Part Context

This component belongs to the MAX6495–MAX6499 family of low-current overvoltage-protection circuits. While sharing core monitoring capabilities, variants differ in features such as undervoltage detection (MAX6499), power-ok indicators (MAX6497/MAX6498), and reverse-battery support (MAX6496). The MAX6495ATT/V+ specifically denotes the automotive-grade version in a 6-pin TDFN package.

Specialized ICS Replacement Considerations

Direct functional substitutes within the same family include the MAX6495ATA+T. For applications requiring reverse-battery protection, consider the MAX6496 series. If undervoltage monitoring is needed, evaluate the MAX6499. Verify pin compatibility and threshold settings before substitution.
