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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
