Power Management IC Series for Automotive Body Control
LED Driver
BD8105FV
No.09039EBT01
●Description
The BD8105FV is a serial parallel control LED driver with 35V input voltage rating.
Responding to the 3-line serial data, it turns the 12ch open drain output on/off.
Due to its compact size, it is optimal for small spaces.
●Features
1) Open Drain Output
2) 3-line Serial Control + Enable Signal
3) Internal Temperature Protection Circuit (TSD)
4) Cascade Connection Compatible
5) SSOP-B20W
6) Internal 12ch Power Transistor
Applications
These ICs can be used with car and consumer electronic.
●Absolute Maximum Ratings (Ta=25℃)
