DESCRIPTION  
The TPS68401/TPS68402 is an advanced lighting management unit for handheld devices. It has three  
independent channels optimized for driving RGB LEDs. The built-in fractional charge pump boosts the input  
voltage to power the LEDs at low input voltage. Channel one can optionally be supplied directly from the battery  
voltage to reduce power consumption and improve efficiency.  
At the heart of the device is a programmable state machine which executes a lighting program consisting of up to  
16 instructions per channel. Once the program is loaded through the I2C interface the device is fully independent  
from the main processor resulting in significant system-level power savings. The device can issue an interrupt to  
the main processor via the INT pin.  
The TRIG I/O allows synchronization between multiple devices. A general-purpose output pin is provided which  
is addressable through the serial interface. In addition, the INT pin can also be configured as general-purpose  
output.
