Constant Current LED Drivers
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.

IC mounted on glass epoxy 2-layer board area 15mmx15mm of the back copper foil, measuring 70mmx70mmx1.6mm.
Pd decreased at 18.4mw/°C for temperatures above Ta=25°C.
HTSOP-J8
IC mounted on glass epoxy 2-layer board area 15mmx15mm of the back copper foil, measuring 70mmx70mmx1.6mm.
Pd decreased at 8.8mW/°C for temperatures above Ta=25°C.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
Recommended Operating Conditions (Ta=-40°C to +125°C)
