Overview
The ISL6144IV is a high-voltage ORing MOSFET controller manufactured by Renesas Electronics Corporation. It is designed for redundant power supply applications, load sharing, and ideal diode emulation. The device operates within a bias voltage range of 9V to 75V and withstands transient voltages up to 100V. Key electrical characteristics include a response time of less than 300 nanoseconds and a dead short response time 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 capability suitable for demanding power systems
- Fast response times for effective protection against faults
- Adjustable reverse voltage threshold for flexible configuration
- Supports load sharing and ideal diode emulation functions
Applications
- Redundant power supply architectures
- Load sharing between multiple power sources
- Ideal diode emulation circuits
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeits. Confirm package type (QFN or TSSOP) matches design requirements. Check RoHS compliance status as per latest manufacturer notices. Ensure proper handling for ESD-sensitive components during assembly.
Selection Notes
Select based on required bias voltage range and transient withstand capabilities. Consider package availability and pin count relative to board layout constraints. Evaluate adjustable threshold needs against system voltage levels. Compare performance metrics with alternative controllers if specific timing requirements are critical.
Part Context
This component belongs to the ISL614x family of ORing controllers. It complements lower-voltage variants like the ISL6146. The family addresses diverse power management needs across industrial and automotive sectors. Renesas provides evaluation boards such as the ISL6144EVAL1Z for design verification.
Replacement Considerations
Consult official substitution lists for direct replacements. Verify pin compatibility and electrical specifications before swapping. Review application notes for any necessary circuit modifications when using alternative parts.
