描述
BD8372HFP-M, BD8372EFJ-M and BD8372UEFJ-M are LED source drivers capable of with standing 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.

BD8372HFP-M,BD8372EFJ-M

●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℃)
