ISL6146EFUZ-T

Overview

The ISL6146EFUZ-T is a low voltage OR-ing FET controller manufactured by Renesas Electronics Corporation. It belongs to the ISL6146 family, designed for N+1 redundancy and power distribution systems. The device operates with an input voltage range of 3V to 20V and features an integrated charge pump to drive N-channel MOSFETs. It provides fast reverse current fault isolation and programmable undervoltage lockout. The component is housed in an 8-MSOP package with dimensions of 3.0 x 3.0 mm and supports surface mount installation.

Feature Summary

• Integrated charge pump enables efficient driving of N-channel power MOSFETs without external components
• Fast response time ensures rapid reverse current fault isolation to protect power sources
• Programmable undervoltage lockout allows precise control over system power supply noise sensitivity
• Open drain fault output pin indicates conditional or FET faults for system monitoring

Applications

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

Procurement Notes

Verify that the specific suffix 'EFUZ' matches the required enable logic and feature set, as variations within the ISL6146 family differ significantly. Confirm the tape and reel packaging quantity aligns with production requirements. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the datasheet revision date to confirm compatibility with existing design documentation.

Selection Notes

Select this variant when independent bias and VIN connections are required alongside active high enable functionality. The ISL6146E variant specifically includes OVP/UVLO inputs on the VIN line. Consider the MSOP package size if board space is limited compared to DFN options. Evaluate the need for conduction monitor reporting capabilities which may vary across other family members.

Part Context

The ISL6146 series replaces traditional power OR-ing diodes to improve efficiency in low voltage applications. This controller family supports voltages from 1V to 18V. The EFUZ-T designation indicates a specific configuration within the MSOP package family, tailored for systems needing robust fault protection and flexible enable control.

Replacement Considerations

Direct substitutes include other variants within the ISL6146 family such as ISL6146AFUZ-T or ISL6146DFRZ, provided the electrical characteristics and pinout configurations match the specific design requirements.
