A total of six commands are available:
Training Start, Training End, Run Once,
Run, Stop, and Reset. Training Start
indicates the beginning of a training
sequence. The PCA9901 starts capturing
the blinking sequence.
Training End indicates the training
sequence is over. The capture stops
and the sequence is stored in the
corresponding registers. The PCA9901
then goes into Shutdown mode.
Run Once tells the PCA9901 to execute
the memorized sequence once and then
go into Shutdown mode. Run tells the
PCA9901 to execute the memorized
sequence until a Stop command occurs.
With the Stop command, the PCA9901
switches the LED output off at the end of
the current LED ON time and goes into
Shutdown mode. The Reset command
tells the PCA9901 to return all the
internal registers to default zones and go
into Shutdown mode.
A single blinking sequence can include
up to three different blinking patterns,
each defi ned by its own ON and OFF
timings.
An external resistor sets the maximum
current that fl ows in the LED, and can be
programmed between 1 and 20 mA.
The driver operates from a power supply
of 2.7 to 5.5 V and is housed in Chip
Scale Package (CSP) that measures only
1.0 x 1.2 x 0.6 mm.
