ISL6146AFRZ-TK

Overview

The ISL6146AFRZ-TK is an obsolete OR-ing MOSFET controller from the Renesas ISL6146 family. It supports voltage OR-ing ranges from 1V to 18V and utilizes an N-channel FET configuration. The component is packaged in an 8-MSOP format and includes a fully integrated charge pump for gate drive voltage generation. This specific part number represents a tape-and-reel variant of the discontinued series.

Feature Summary

• Supports OR-ing voltages from 1V to 18V
• Utilizes N-channel MOSFET configuration
• Features fully integrated charge pump for gate drive

Applications

• N+1 ORing Controller applications
• Load sharing systems
• Power management circuits requiring voltage OR-ing

Procurement Notes

This component is officially listed as Obsolete by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Ensure that the received units match the exact suffix specifications, as legacy inventory may vary in packaging or handling conditions. Cross-reference with current Renesas product portfolios for viable alternatives.

Selection Notes

Select this component only if legacy system compatibility requires the specific MSOP package and N-channel architecture of the ISL6146 series. Given its obsolete status, engineers must evaluate the long-term supply chain risks associated with discontinuation. Consider migrating to newer Renesas OR-ing controllers that offer updated features and active lifecycle status while maintaining functional equivalence.

Part Context

The ISL6146AFRZ-TK belongs to the broader ISL6146 family of low-voltage OR-ing FET controllers manufactured by Renesas Electronics Corporation (formerly Intersil). This family is designed for power management applications where multiple power sources need to be combined efficiently. The 'AF' suffix typically denotes specific electrical characteristics within the series, while 'TK' indicates the tape-and-reel packaging format.

Replacement Considerations

Direct substitutes include other variants within the ISL6146 family such as ISL6146DFRZ or ISL6146BFRZ, which share similar OR-ing controller functionalities but may differ in package type or channel configuration. Engineers should verify pin compatibility and electrical parameters when transitioning between these related part numbers.
