1 Features 3 Description For automotive off-board sensors and low-current offboard modules, the power supply is through a long
cable from the main board. In such cases, protection
is required in the power devices for the off-board
loads to prevent the onboard components from
damage during a short to GND or short to battery
caused by a broken cable. Off-board sensors require
a power supply as consistent as that for onboard
components to secure high accuracy of data
acquisition. 1 Qualified for Automotive Applications
