3-Channel Fun LED Driver
Description
SN3193 is a 3-channel fun LED driver which features
two-dimensional auto breathing mode. It has One Shot
Programming mode and PWM Control mode for RGB
lighting effects. The maximum output current can be
adjusted in 5 levels (5mA~42mA).
In PWM Control mode, the PWM duty cycle of each
output can be independently programmed and controlled
in 256 steps to simplify color mixing. In One Shot
Programming mode, the timing characteristics for output
current - current rising, holding, falling and off time, can
be adjusted individually so that each output can
independently maintain a pre-established pattern
achieving mixing color breathing or a single color
breathing without requiring any additional interface
activity, thus saving valuable system resources.
SN3193 is available in DFN-10 (3mm × 3mm). It
operates from 2.7V to 5.5V over the temperature range of
-40°C to +85°C.
