MAX6496ATA/V+T

Specialized ICS Overview

The MAX6496ATA/V+T is an overvoltage-protection controller designed for high-voltage transient systems in automotive and industrial applications. It operates within a supply voltage range of +5.5V to +72V and monitors input voltage to control an external pMOSFET switch, isolating the load during overvoltage conditions. The device features an integrated charge pump that provides a 10V gate-to-source enhancement voltage to fully enhance the external MOSFET. When the monitored input exceeds the user-adjustable threshold, the gate is quickly pulled low to disconnect the load. This specific variant supports lower input voltages and reduces power loss by replacing the external reverse battery diode with an external series pMOSFET.

Specialized ICS Feature Summary

• Integrated charge-pump circuit provides 10V gate-to-source enhancement for low RDS(ON) performance
• Supports series pMOSFET configuration for reverse-battery voltage protection
• Fast gate shutoff during overvoltage events with 100mA sink capability
• Adjustable overvoltage threshold via external resistive divider network

Specialized ICS Applications

• Automotive electronics
• Industrial high-voltage transient systems
• Reverse-battery protection circuits

Specialized ICS Procurement Notes

Verify the package type matches the required 8-TQFN (3x3) footprint. Confirm the component meets AEC-Q100 qualification standards if used in automotive environments. Ensure the ordering suffix corresponds to the Tape & Reel packaging format specified for this part number.

Specialized ICS Selection Notes

Select the MAX6496 when reverse-battery protection is required using a pMOSFET instead of a diode to minimize voltage drop. Ensure the external pMOSFET can handle the maximum expected current and voltage stress. Verify that the thermal management strategy accounts for the junction temperature limits during prolonged overvoltage events.

Specialized ICS Part Context

This component belongs to the MAX6495–MAX6499 family of small, low-current overvoltage-protection circuits. While other variants in the family support nMOSFET switches or include additional features like undervoltage monitoring or power-OK indicators, the MAX6496 specifically focuses on reverse-battery protection using a pMOSFET.
