ISL6146CFUZ-T

Overview

The ISL6146CFUZ-T is a low-voltage OR-ing MOSFET controller manufactured by Renesas Electronics Corporation. It is designed to replace power OR-ing diodes in high-efficiency power distribution systems, utilizing N-channel power MOSFETs with an integrated charge pump. The device supports voltage inputs from 1V to 18V and features a programmable undervoltage lockout. It allows users to adjust the OUT-V trip point via external resistors to control sensitivity to system power supply noise. An open-drain FAULT pin indicates conditional or FET faults. The component operates within a temperature range of -40°C to +125°C and is housed in an 8-lead MSOP package.

Feature Summary

• Integrated charge pump enables efficient operation with N-channel power MOSFETs
• Adjustable OUT-V trip point for customizable control sensitivity
• Open-drain FAULT pin provides fault indication
• Optimized for low-voltage operation down to 1V

Applications

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

Procurement Notes

Verify the specific suffix 'CFUZ-T' against official Renesas documentation to confirm package type and tape-and-reel configuration. Check for End-of-Life (EOL) notifications or Product Change Notices (PCNs) as the ISL6146 family has undergone discontinuance actions. Ensure compatibility with existing board layouts and thermal requirements before procurement.

Selection Notes

Select this model when designing systems requiring low-voltage OR-ing functionality with N-channel MOSFETs. Consider the MSOP-8 package for space-constrained applications. Evaluate the need for adjustable trip points and fault monitoring capabilities. Compare against other variants like ISL6146AFUZ-T or ISL6146BFRZ based on specific voltage ranges and packaging preferences.

Part Context

The ISL6146 series consists of OR-ing MOSFET controllers aimed at improving power distribution efficiency. Variants include ISL6146A, B, C, D, and E, differing in voltage optimization and package types such as DFN-8 and MSOP-8. The ISL6146CFUZ-T is part of this family, specifically tailored for low-voltage applications with an MSOP package.

Replacement Considerations

Direct substitutes include ISL6146AFUZ-T and ISL6146BFRZ-TK, which share similar OR-ing controller functionalities but may differ in package or voltage optimization. Verify pin compatibility and electrical specifications before substitution.
