ISL6146CFUZ-T7A

Overview

The ISL6146CFUZ-T7A is a low voltage OR-ing FET controller manufactured by Renesas Electronics Corporation. It operates within a bias voltage range of 3V to 20V and withstands transients up to 24V. The device features a dead short response time of less than 300ns and a slow turn-off response time of less than 80μs. It utilizes an adjustable reverse voltage threshold resistor, configurable between 40mV and 800mV. The component is housed in an 8-lead MSOP package with dimensions of 3.0mm x 3.0mm x 0.7mm pitch.

Feature Summary

• Implements N+1 ORing control for redundant power distribution systems
• Provides fast protection against dead short conditions
• Supports load sharing and current balancing functions

Applications

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

Procurement Notes

Verify the specific suffix 'T7A' corresponds to the required reel packaging configuration. Confirm that the 'C' variant designation aligns with the intended electrical specifications and thermal requirements for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring low voltage redundancy and precise current sharing. Ensure the input voltage stays within the 3V to 20V operating range. Consider the MSOP package size if board space is constrained compared to DFN alternatives.

Part Context

This part belongs to the ISL6146 series of OR-ing controllers designed for low voltage applications. It serves as a critical component for ensuring system reliability in power distribution networks by managing parallel power sources and preventing backflow currents.

Replacement Considerations

Direct substitutes include ISL6146AFUZ-T and ISL6146BFRZ-TK. Verify pinout compatibility and parameter alignment when transitioning between different package types or manufacturer suffixes.
