Keywords: Power MOSFET  field-effect transistor  automotive power delivery 

[Summary of tips] The automotive lighting system requires peak in-rush current of up to 55A. Using relays and fuses in a conventional method to switch and limit the current for power delivery can be unpredictable and unreliable. Combining a high-side pre-FET driver and power FET is an optimal solution to control a vehicle's lighting system.View ......
