BD8115F-M
rreevv..00..344
Description
The BD8115F is a serial parallel control LED driver with 35V input voltage rating.
Responding to the 3-line serial data, it turns the 8ch 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) SOP16
6) Internal 8ch Power Transistor
zApplications
These ICs can be used with car and consumer electronic.
