LED Driver IC
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.

Technical Note
3Enable Signal
By applying voltage at least VCC×0.8 or more to the SDWN terminal, D0~D7 become open forcibly. At this time, the
temperature protection circuit (TSD) stops. D7D0 become PWM operation by inputting PWM to SDWN.
4SEROUT
A cascade connection can be made (connecting at least 2 or more IC’s in serial).
Serial signal input from SERIN is transferred into receiver IC by the fall edge of the CLK signal.
Since this functionality gives enough margins for the setup time prior to the rise edge of the CLK signal on the receiver
IC (using the exact same CLK signal of sender IC), the application reliability can be improved as cascade connection
functionality.

Cascade Connection
By using (at least) 2 ICs, each IC’s D7~D0, at (at least) 16ch, can be controlled by the 16-bit SERIN signal. The serial data
input to the sender IC can be transferred to the receiver IC by inputting 8CLK to the CLK terminal.
