NSI6611ASC-Q1SWR is listed in the Isolators - Gate Drivers range at ChipApex. The manufacturer field lists NOVOSENSE. Its product description is 1-CHANNEL ISO SMART GATE DRIVER. Review the specifications below when checking this part for your BOM.
The NSI6611ASC-Q1SWR is a single-channel isolated smart gate driver manufactured by NOVOSENSE. It features capacitive coupling with a 5700Vrms isolation voltage rating and operates within an output supply voltage range of 13V to 32V. Designed for automotive applications, it supports an operating temperature range from -40°C to 125°C. The component is housed in a 16-SOIC surface-mount package.
Verify the specific suffix 'Q1' confirms automotive grade compliance and 'SWR' indicates tape-and-reel packaging. Confirm the 16-SOIC package dimensions match PCB layout requirements. Ensure the 5700Vrms isolation rating meets system safety standards. Validate the -40°C to 125°C operating temperature range against environmental conditions.
Select this component when a single-channel isolated drive solution is required for high-voltage power switches. The wide input supply range accommodates various gate drive configurations. Automotive qualification makes it suitable for electric vehicle traction inverters or on-board chargers where reliability under thermal stress is critical.
NOVOSENSE specializes in analog and mixed-signal chips for automotive and industrial sectors. This part belongs to their isolated gate driver family, designed to replace traditional transformer-based drivers with more compact capacitive solutions. The Q1 designation signifies adherence to automotive quality standards.
Check pinout compatibility with existing designs. Verify that the replacement device supports the same 13V-32V supply range and 5700Vrms isolation level. Ensure the SO-16 package footprint matches the current PCB layout without modification.
