Frequently Asked Questions
How many LED channels does the LP5523TM/NOPB support?
The LP5523TM/NOPB supports 9 independent programmable LED current channels. These channels can drive RGB LEDs (three channels per color: red, green, blue) plus additional white LED channels, allowing full color mixing and independent brightness control for each channel through the I2C serial interface.
What is the internal program memory used for in the LP5523TM/NOPB?
The LP5523TM/NOPB includes internal program memory that stores LED animation sequences and lighting patterns. This allows the device to execute complex LED effects autonomously without continuous CPU intervention, which reduces host processor load and system power consumption, especially during idle or standby modes in battery-powered devices.
What package is the LP5523TM/NOPB available in?
The LP5523TM/NOPB is housed in a 25-ball DSBGA (Die-Size Ball Grid Array) package, which is an ultra-compact surface-mount package designed for minimum board space consumption. This package is ideal for space-constrained applications such as smartphones, smartwatches, and other miniaturized portable electronics where PCB real estate is at a premium.
Does the LP5523TM/NOPB require an external charge pump?
No, the LP5523TM/NOPB integrates a charge pump internally, which eliminates the need for external boost converter components. The integrated charge pump generates the elevated voltage required to drive LEDs at consistent current levels even when the supply voltage is lower than the LED forward voltage, simplifying the overall circuit design and reducing component count.
