NV9581F1C1-RA is listed in the AC DC Converters, Offline Switchers range at ChipApex. The manufacturer field lists Navitas Semiconductor, Inc.. Its product description is GANSENSE CONTROL 700V 210MOHM PQ. Review the specifications below when checking this part for your BOM.
The NV9581F1C1-RA is a GaNSense Control integrated circuit from Navitas Semiconductor, classified as specialized power management (PMIC). It features a 700V rating and an on-resistance of 210mOhm. The device operates within a temperature range of -40°C to +125°C and supports a maximum input voltage of 77V. It consumes 750uA of operating supply current and is housed in a 23-lead PQFN package for surface mount installation.
Verify the specific suffix RA against official datasheets to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure the QFN-23 thermal pad requirements are met during PCB layout to maintain reliability within the specified operating temperature range.
Select this component when a 210mOhm on-resistance is required for the specific power stage. Compare against other NV958x variants if different resistance values or pin configurations are needed. Verify that the 77V input limit aligns with the system's maximum voltage rails and that the 750uA quiescent current fits the efficiency targets.
This part belongs to the GaNSense Control series, which integrates controller functions with GaN power devices. It represents a specialized PMIC solution designed to simplify the design of high-efficiency power converters by combining control logic with power switching capabilities in a single package.
Consult the official datasheet for direct pin-to-pin compatible alternatives within the NV958x family. Verify functional equivalence for any substitute parts regarding gate drive characteristics and control interface compatibility.
