Description

General part information

BD1LBU50EFJ-C Series

BD1LBU50EFJ-C is an in-vehicle 1ch low side switch. This switch builds in the overcurrent limiting circuit, thermal shutdown circuit, open load detection circuit and under voltage lock out circuit. It also provides the diagnostic output circuit when an abnormality is detected.
