50V 200mA
1ch Source Driver for Automotive
BD8372HFP-M BD8372EFJ-M
General Description
BD8372HFP-M and BD8372EFJ-M are LED source
drivers capable of withstanding high input voltage (50V
MAX). The constant current output is set by either of
two external resistors. It has built-in LED open/short
protection, external resistance open/short protection
and overvoltage protection that can achieve high
reliability. It is possible to control all LEDs together and
turn OFF even if LED causes short/open in a certain
row when driving two or more LEDs by using multiple
ICs.
