NSE11409-Q1 1CH, 90mΩ, 40V, Fully Protected Automotive
Low-side Switch
Datasheet (EN) 1.0
Product Overview
NSE11409-Q1 is a 90mΩ low-side switch with 48V clamp voltage for automotive applications. It’s designed for driving resistive or inductive loads with one side connected to the battery. Internal 48V clamp circuit protects device from surge energy when fast demagnetization at turn-off.
With internal output current limitation, the device is protected in overload condition. Built-in thermal shutdown protects the chip from over-temperature and short-circuit. A thermal swing mechanism is built to limit dissipated power to decelerate power accumulation. Thermal shutdown, with automatic restart, allows the devices to recover normal operation as soon as a fault condition disappears.
