Overview
The ISL6146AFUZ-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 transient voltages up to 24V. The device features a response time for dead short conditions of less than 300 ns and a slow turn-off response time to power supply (PS) of less than 80 μs. It utilizes an adjustable ramp voltage reverse voltage threshold resistor, with a range from 40mV to 800mV. The component is housed in an MSOP package with dimensions of 3.0 x 3.0 mm and a pitch of 0.7 mm.
Feature Summary
- Provides N+1 redundancy control for parallel power supplies
- Features fast dead short protection response
- Supports adjustable reverse voltage threshold
Applications
- N+1 Industrial and Telecom Power Distribution Systems
- Uninterruptible Power Supplies
- Low Voltage Processor and Memory Storage and Datacom Systems
Procurement Notes
Verify the specific suffix T7A against official Renesas documentation to confirm reel quantity and tape specifications. Confirm current availability status as distribution data indicates potential end-of-life or discontinuation trends for the broader ISL6146 family. Ensure compatibility with existing board layouts before procurement.
Selection Notes
Select this component for applications requiring precise load sharing and hot-swap capabilities in low voltage environments. Consider the MSOP package size for space-constrained designs. Evaluate the need for adjustable reverse voltage thresholds to match specific system requirements.
Part Context
The ISL6146 series includes variants such as ISL6146D, ISL6146B, and ISL6146A, offering ORing controller functionality. These devices are designed for power management in telecom and industrial systems. The AFUZ-T7A variant specifically denotes the MSOP package and tape-and-reel packaging format.
Replacement Considerations
Direct substitutes include ISL6146DFRZ and ISL6146BFRZ-TK. Verify pinout and electrical characteristics against datasheets before substitution.
