ISL6144IRZA

Overview

The ISL6144IRZA is a high-voltage ORing MOSFET controller manufactured by Renesas Electronics Corporation. It is designed for redundant power supply applications, managing load sharing and protection in systems requiring high reliability. The device operates with a bias voltage range of 9V to 75V and features a transient voltage withstand capability of up to 75V. Key electrical parameters include a response time of less than 300 nanoseconds and a dead short response time to PS of less than 100 microseconds. The reverse voltage threshold is resistor-adjustable from 0V to 5.3V. It is available in 16-pin QFN and 20-pin TSSOP packages.

Feature Summary

High-voltage operation suitable for demanding power management environments
Fast transient response for effective load protection
Resistor-adjustable reverse voltage threshold for flexible configuration

Applications

Redundant power supply systems
Load sharing in multi-source power architectures
High-reliability industrial power management

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm package type (QFN or TSSOP) matches design requirements. Check latest datasheet revisions for any parameter updates. Ensure compliance with RoHS3 specifications. Validate supplier credentials before purchase.

Selection Notes

Select based on required bias voltage range and package constraints. Consider the adjustable reverse voltage threshold for system-specific protection levels. Evaluate thermal performance within the chosen package option. Compare response times against system protection requirements. Verify compatibility with existing control circuitry.

Part Context

The ISL6144 belongs to Renesas' family of ORing FET controllers, specifically targeting high-voltage applications. It complements lower-voltage variants like the ISL6146. This component addresses the need for robust power path management in critical infrastructure where redundancy and fast fault response are essential for system uptime and safety.
