Longer standby times in mobile

and portable applications

By ofﬂ oading the microcontroller and using this small, easily programmed driver to control the

blinking of an indicator LED, the standby power in a cell phone or other portable device can be

extended by as much as 30%.

driver for cell phones

PCA9901

Applications

When the battery in a cell phone or other portable device runs

low, the blinking indicator LED can consume as much as 40%

of the system’s available standby power. Using the NXP onewire

single LED driver, a six-pin driver that enables standalone

blinking of a predeﬁ ned pattern, instead of the system’s

microcontroller to manage the blinking, power consumption

can be reduced by up to a factor of four, requiring only 10% of

the available standby power.

Programming the PCA9901 is simple. The host controller sends

the blink sequence over a uni-directional, one-wire interface

to the CTRL pin. The PCA9901 captures the sequence and

memorizes it at the same time. Then the controller also sends

commands that instruct the PCA9901 to execute the sequence

once or in a loop until notiﬁ ed to stop.
