Automotive 40V Dual-channel 90mΩ Intelligent Low-Side Switch
NSD12409 is a dual-channel intelligent low-side switch developed for automotive 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 qualification. The IC is designed with an integrated overvoltage clamp of > 45V, which is especially suitable for driving inductive loads such as relays and valves to help them realize rapid demagnetization. The chip has internal output current limiting function to realize overload and short circuit protection. Built-in absolute overtemperature protection and relative overtemperature protection prevent chip overheating in multiple ways, so that improves chip reliability. The chip can be operated at ambient temperature from -40°C to 125°C, with SOP8 package to meet different design requirements.
