Unique LED Driver IC by Kinetic Technologies Offers RGB Plus Selfie Flash Driver in Tiny Package


Power management leader Kinetic Technologies is announcing the industry's first front-side solution LED driver for smartphones, the KTZ8807.

This innovative constant-current LED driver combines a programmable RGB indicator LED driver with a high current white LED front-side (selfie) flash driver. Using I2C compatible LED control and programmability, the KTZ8807 features superior user-control through its adjustable on-chip timing control unit: LED blink rate and fade-in and fade-out, are user adjustable, resulting in a range of unique color lighting patterns when driving RGB LEDs. An external strobe pin facilitates simple control of the selfie flash output, also compatible with infrared LEDs, and includes a safety timer to terminate the flash event under fault conditions.

"Newer generations of mobile phones with front-facing cameras require adjustable current regulators to drive white LEDs for camera flash," says Kinetic Technologies Vice President David Nam. "The KTZ8807 does just that. Our fully programmable, constant current RGB LED driver, paired with a high current white LED driver provides four independent programmable low dropout, constant current sinks without requiring any external components, simplifying design and reducing component count."

Additional control is offered via en programmable internal registers, which, through the I2C control interface and built-in decoder, allow adjustability of the LED channels' ON (News - Alert)/OFF states and 193 current levels - ranging from 0.125mA to 24mA for channels D1-D3 and 39 current levels - up to 600mA for channel D4.



The device also features AutoBlinQ technology, which automatically turns LED1 on and off, at a pre-programmed blink rate, when no I2C command is received within 1s after power-up. In a Smartphone with a deeply discharged battery, this can advise users that the phone is charging.

The KTZ8807 is available in a PB-Free, UTDFN 2.0mm x 2.0mm package.


Key applications for the Kinetic Technologies KTZ8807 include mobile phones, handheld devices, RGB indicator LEDs, front side (selfie) flash and infrared iris detection and communication.

The KTZ8807 is available and shipping now. Visit Kinetic Technologies for more information.
