ISL6146DFUZ-T

Overview

The ISL6146DFUZ-T is a low voltage OR-ing FET controller from the ISL6146 family, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 20V and supports N-channel MOSFETs for power distribution efficiency. The device features an internal charge pump, programmable undervoltage lockout, and fault output capabilities. It is housed in an MSOP-8 package with a wide operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated charge pump drives N-channel MOSFETs for efficient power OR-ing
• Programmable undervoltage lockout and user-adjustable trip points via external resistors
• Open-drain FAULT pin indicates conditional or FET faults
• Fast reverse current fault isolation with smooth switching transitions

Applications

• N+1 Industrial and Telecom Power Distribution Systems
• Uninterruptible Power Supplies (UPS)
• Low Voltage Processor and Memory Storage Systems
• Datacom Systems

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as indicated in official documentation. Check for End-of-Life notifications or product discontinuance updates from Renesas Electronics Corporation prior to final procurement decisions.

Selection Notes

Select this controller for applications requiring high-efficiency power OR-ing with low voltage operation down to 3V. Ensure compatibility with N-channel MOSFETs and verify that the MSOP-8 package fits the design constraints. Consider the programmable fault detection and UVLO features for system protection requirements.

Part Context

The ISL6146 series includes variants like ISL6146A, B, C, D, and E, differing in bias configurations and feature sets such as conduction monitoring. The DFUZ suffix denotes the MSOP-8 package type. This specific model is part of a family designed to replace power OR-ing diodes for improved efficiency.

Replacement Considerations

Direct substitutes include other ISL6146 family members like ISL6146DFRZ or ISL6146AFUZ depending on package and feature needs. Verify pin compatibility and electrical specifications before substitution.
