ISL6146CFRZ-T

OR Controllers, Ideal Diodes Overview

The ISL6146CFRZ-T is a low-voltage OR-ing FET controller from the Renesas ISL6146 family, designed for N-channel MOSFET applications. It operates with a supply voltage range of 3V to 20V and supports input voltages from 1V to 18V. The device features an internal charge pump to drive N-channel power MOSFETs, replacing traditional diode OR-ing configurations to improve efficiency. Key electrical parameters include a maximum shutdown delay time of 65 ns and a typical operating supply current of 4.5 mA. It is housed in an 8-lead DFN package (3x3 mm) and functions within a temperature range of -40°C to +125°C.

OR Controllers, Ideal Diodes Procurement Notes

Verify component authenticity through authorized channels as the product line may be subject to discontinuation notices. Confirm that the specific suffix corresponds to tape and reel packaging requirements for automated assembly processes. Ensure compatibility with RoHS standards and check for any recent process change notifications regarding lead materials or labeling formats before finalizing procurement orders.

OR Controllers, Ideal Diodes Selection Notes

Select this model when designing systems requiring low-voltage operation down to 3V with independent bias capabilities. The ISL6146C variant specifically offers programmable undervoltage lockout suitable for sensitive load applications. Consider the 65 ns turn-off delay for fast reverse current fault isolation. Evaluate the 8-DFN package dimensions for space-constrained PCB layouts compared to MSOP alternatives.

OR Controllers, Ideal Diodes Part Context

The ISL6146 series represents a family of OR-ing MOSFET controllers manufactured by Renesas Electronics Corporation, formerly Intersil. This component replaces standard power diodes in high-efficiency power distribution networks. The FRZ suffix indicates the specific DFN-8 package configuration, while the T suffix typically denotes tape and reel packaging for surface-mount technology integration.

OR Controllers, Ideal Diodes Replacement Considerations

Direct substitutes within the same family include ISL6146AFUZ, ISL6146BFRZ, ISL6146DFRZ, and ISL6146EFRZ. These variants differ primarily in feature sets such as conduction monitoring availability and enable pin logic levels. Verify pin-to-pin compatibility and ensure the alternative part number supports the required 3V minimum supply voltage and N-channel MOSFET drive requirements.
