AP74700QW6-7

Overview

The AP74700QW6-7 is a power distribution ideal diode controller manufactured by Diodes Incorporated. It operates within a supply voltage range of 3.2 V to 65 V and supports an output current of 1.85 A. The device features a maximum on-resistance of 2 Ohms and functions across a temperature range of -40 C to +125 C. Packaged in an SOT26-6 surface-mount format, it is designed for efficient power switching applications requiring low forward voltage drop.

Feature Summary

• Functions as an ideal diode controller to minimize power loss through low on-resistance
• Supports high input voltage ranges up to 65 V for versatile power distribution
• Automotive-grade reliability with extended operating temperature capabilities

Applications

• Power distribution systems requiring reverse current blocking
• N+1 redundancy configurations in server or industrial power supplies
• Hot-swap controller circuits for system protection

Procurement Notes

Verify the specific suffix W6 corresponds to the SOT26-6 package configuration required for your layout. Confirm that the 1.85 A output current rating aligns with your peak load requirements. Ensure the 3.2 V minimum operating voltage is compatible with your system's standby states. Cross-reference the RoHS status if environmental compliance is mandatory for your region.

Selection Notes

Select this component when a compact solution for high-voltage ideal diode control is needed. The SOT26-6 package offers a balance between thermal performance and board space efficiency compared to larger packages. Consider the 2 Ohm on-resistance limit against your acceptable power dissipation levels. This part serves as a direct functional alternative to similar Texas Instruments controllers in automotive and industrial designs.

Part Context

This component belongs to the AP74700 series of ideal diode controllers from Diodes Incorporated. It is engineered to replace traditional Schottky diodes in power paths, thereby reducing conduction losses. The series is characterized by its ability to drive external N-channel MOSFETs with optimized gate drive timing to prevent reverse current flow effectively.

Replacement Considerations

The LM74700QDBVTQ1 is a documented substitute part number for this component.
