Datasheet
Serial-in Parallel-out LED Driver
12ch LED Driver IC
with 3-line Serial Interface
BD8379FV-M
General Description
The BD8379FV-M is a serial-in parallel-out controlled
LED driver with 35V output voltage rating.
With the input of 3-line serial data, it turns the 12ch
open drain output on/off.
Due to its compact size, it is optimal for small space.
Features
Open Drain Output.
3-line Serial Control + Enable Signal.
Cascade Connection Compatible.
SSOP-B20 Package.
Internal 12ch Power Transistor.
Output Slew Rate Typical 20V/μs
(for Low EMC Noise).
AEC-Q100 Qualified.
