●Description
BD8372HFP-M and BD8372EFJ-M are a LED source driver with the capability of withstanding high input voltage (50V MAX).
The fixed current output can change in the H/L current, and it is the best for automotive LED drive. It is built into LED
open/short protection, external resistance open/short protection and overvoltage overheating protection and high reliability
can be achieved. When driving two or more LED by using two or more IC, it can be done to control LED all together turning
off even if LED causes short/open in a certain row.
●Features
1) Input voltage range 5.5～40V
2) Changeable type fixed current source driver(200 mA max), Current accuracy ±3%(VIN=13 V, Ta=25℃)
3) H/L Current setting switch control
4) Built-in LED open/short protection circuit
5) Built-in ISET open/short protection circuit
6) Built-in overvoltage overheating protection and temperature protection circuit
7) Error state output detection function (PBUS)
8) HRP7/HTSOP-J8 package
●Applications
For automotive (Lear lamp, Interior light, etc.)
●Absolute maximum ratings (Ta=25℃)

●Current control at output saturation
When VIOUT(=VF) exceeds VIN-0.4V, the current is decreased for a set current. Therefore, because VF decreases due to IF
decrease of LED, Threshold VOUT=VIN-0.2V of open detection can be prevented keeping the relation of VIOUT≦VIN-0.4V,
and being exceeded. The current control must become IOUT<20µA and IF must select LED for VF not to exceed
VUVLO_OPEN by 20µA.

●PROTECT BUS (PBUS)
PUBS is an I/O terminal that outputs error and the terminal that detects error. When error occurs because of open/short of
external parts etc. , Low is output from Hi(Hi-Z) with PBUS terminal, and it is possible to detect error from the outside. The
output current can be turned off by controlling. PUBS to Hi→Low from outside. LED of all rows can control turning off even if
open/short circuit of LED occurs because it connects the terminal PUBS of each CH as shown in following figure when
driving two or mode LED by useing two or mode this IC.

Technical Note

●Notes for use
1. Absolute maximum ratings
We are careful enough for quality control about this IC. So, there is no problem under normal operation, excluding that it
exceeds the absolute maximum ratings. However, this IC might be destroyed when the absolute maximum ratings, such
as impressed voltages or the operating temperature range (Topr), is exceeded, and whether the destruction is short circuit
mode or open circuit mode cannot be specified. Please take into consideration the physical countermeasures for safety,
such as fusing, if a particular mode that exceeds the absolute maximum rating is assumed.
2. Reverse polarity connection
Connecting the power line to the IC in reverse polarity (from that recommended) will damage the part. Please utilize the
direction protection device as a diode in the supply line.
3. Power supply line
Please design the power supply line where a large current is thrown to reduce the resistance of the wiring for the power
supply pattern so that there is a possibility of usually influencing operation.
4. GND line
The ground line is where the lowest potential and transient voltages are connected to the IC.
Please confirm whether there is actually terminal that is the voltage of GND or less including transients.
5. Thermal design
Do not exceed the power dissipation (Pd) of the package specification rating under actual operation, and please design
enough temperature margins. This product has exposed the frame to the back side of the package, but please note that it
is assumed to use heat radiation efficiency by the heat radiation for this part. Please take the heat radiation pattern on not
only the surface of the substrate but also the back of the substrate widely.
6. Short circuit mode between terminals and wrong mounting
Do not mount the IC in the wrong direction and displacement, and be careful about the reverse-connection of the power
connector. Moreover, this IC might be destroyed when the dust short the terminals between them or GND.
( The outputs of CH1(pin2,3) have NO protection circuit. So please especially be careful about them.)
7. Radiation
Strong electromagnetic radiation can cause operation failures.
8. TSD (Thermal Shut-Down)
The TSD is activated when the junction temperature (Tj) exceeds Tjmax, and the output terminal is switched to OPEN.
The guarantee and protection of set are not purpose. Therefore, please do not use this IC after TSD circuit operates, nor
use it for assumption that operates the TSD circuit.
9. Inspection by the set circuit board
The stress might hang to IC by connecting the capacitor to the terminal with low impedance. Then, please discharge
electricity in each and all process. Moreover, when attaching or detaching from jig in the inspection process, please turn off
the power before mounting the IC, and turn on after mounting the IC, and vice versa. In addition, please take into
consideration the countermeasures for electrostatic damage, such as giving the earth in assembly process, transportation
or preservation.
10. Input terminal
This IC is a monolithic IC, and has P+ isolation and P substrate for the element separation. Therefore, a parasitic PN
junction is firmed in this P-layer and N-layer of each element. For instance, the resistor or the transistor is connected to the
terminal as shown in the figure below. When the GND voltage potential is greater than the voltage potential at Terminals A
on the resistor, at Terminal B on the transistor, the PN junction operates as a parasitic diode. In addition, the parasitic NPN
transistor is formed in said parasitic diode and the N layer of surrounding elements close to said parasitic diode. These
parasitic elements are formed in the IC because of the voltage relation. The parasitic element operating causes the
interference of circuit operation, then the wrong operation and destruction. Therefore, please be careful so as not to
operate the parasitic elements by impressing to input terminals lower voltage than GND (P substrate). Please do not apply
the voltage to the input terminal when the power-supply voltage is not impressed. Moreover, please impress each input
terminal lower than the power-supply voltage or equal to the specified range in the guaranteed voltage when the
power-supply voltage is impressing.
