Smart low side switches are mainly used in vehicle controllers, vehicle controllers, power distribution controllers, BMS and other scenarios, especially suitable for driving inductive loads such as relays and valves, helping them achieve rapid demagnetization. Unlike the intelligent high side switch which directly cuts off the current from the power supply, the intelligent low side switch protects the load by cutting off the current path in GND through the switch. Usually, low side switches are used to replace traditional MOSFETs when multiple power sources are present.
