ISL6144IVZA

Overview

The ISL6144IVZA is a high-voltage ORing MOSFET controller manufactured by Renesas Electronics Corporation. It is designed for power management applications requiring load sharing and redundancy. The device supports a bias voltage range of 9V to 75V and withstands transient voltages up to 100V. Key electrical specifications 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 TSSOP packages.

Feature Summary

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type availability as the ISL6144 series offers multiple options. Check for end-of-life notices or product change notifications regarding labeling updates. Ensure compliance with RoHS3 standards if required for specific environmental regulations. Validate supply chain integrity to avoid counterfeit components.

Selection Notes

Select this controller for high-voltage ORing applications requiring precise load balancing. Consider the adjustable reverse voltage threshold for custom current limit settings. Evaluate the fast response characteristics for sensitive datacom or telecom environments. Compare against low-voltage alternatives like the ISL6146 if operating below 20V. Ensure the chosen package fits the thermal and spatial constraints of the design.

Part Context

The ISL6144 belongs to Renesas' family of ORing controllers, specifically targeting high-voltage scenarios. It complements lower-voltage counterparts such as the ISL6146, which operates within a 3V to 20V range. This component is part of the broader power management portfolio aimed at improving system reliability and efficiency in critical infrastructure applications.
