 The new LED driver (power logic) family from STMicroelectronics fully integrates all functions required to drive high-
brightness LEDs.

These devices allow constant-current control in a single-chip solution. The external parts are reduced to only one
resistor which sets the preferred maximum current for all outputs.

An innovative feature of this family is the clock and data resynchronization; this occurs when the devices are connected
in cascade. Devices also come with additional features such as high current, high precision,
