NSE11409-QSTBR

Overview

The NSE11409-QSTBR is a single-channel automotive-grade smart low-side switch manufactured by NOVOSENSE. Designed for high-reliability load applications, it features a 40V withstand voltage and an internal MOSFET with a typical on-resistance of 90mΩ. The device supports operation across a wide temperature range from -40°C to 125°C and complies with AEC-Q100 standards. It integrates comprehensive protection mechanisms including over-voltage clamping exceeding 45V, current limiting above 8A, and thermal shutdown.

Feature Summary

Integrates over-voltage clamping exceeding 45V to protect against inductive load kickback
Provides active current limiting and over-temperature protection for robust fault management
Offers open-circuit diagnostic output capability for system monitoring

Applications

Driving automotive relays
Controlling solenoid valves
Powering heating resistors

Procurement Notes

Verify the specific suffix 'QSTBR' against official NOVOSENSE documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with target PCB footprint dimensions for the SOT-223 or SO-8 variant as defined in the datasheet. Confirm that the selected revision meets the required AEC-Q100 qualification level for the intended automotive application environment.

Selection Notes

Select this component when driving inductive loads such as relays or valves requiring high surge tolerance. The integrated over-voltage clamp eliminates external snubber circuits. Choose based on the need for diagnostic feedback via the open-circuit detection feature. Ensure the load current remains within the 8A limit and thermal dissipation requirements are met for the chosen operating temperature range.

Part Context

This part belongs to the NSE11409 series of smart low-side switches from NOVOSENSE. The series is engineered for automotive environments, offering high reliability and compact integration. It replaces discrete solutions by combining power switching with advanced protection and diagnostics in a single package, simplifying design for body electronics and thermal management systems.
