Automotive 40V Single Channel 90mΩ Smart Low Side Switch
NSE11409 is a single-channel smart low-side switch developed for automobile and industrial applications, featuring a withstand voltage of > 40V, and an internal resistance of about 90mΩ, it allows various diagnostic functions and different protections, and has passed AEC Q100 certification.
The IC is designed with a built-in VDD clamp of> 45V, which is especially suitable for driving inductive loads such as relays and valves to help them realize rapid demagnetization/deenergization. The IC is designed with an internal output current limiting function for overload protection and short circuit protection.
