What are the key features of LP5524TM-5?
- 9 independent constant-current LED output channels with up to 25.5 mA per channel and on-chip 192-byte program memory for autonomous RGB and white LED animation patterns
- I2C interface with programmable LED brightness (256 steps per channel) and a built-in sequencer that executes lighting programs without host CPU intervention
- Ultra-compact 9-ball WAFER-LEVEL BGA (1.6 x 1.6 mm footprint) minimises board space for LED indication in smartphones, wearables, and compact IoT devices
What is LP5524TM-5 used for?
The LP5524TM-5 is designed for RGB LED status indicators, notification lights, and ambient lighting in smartphones, wearables, hearables, and compact IoT devices where autonomous LED sequencing is needed without continuous microcontroller intervention. Its on-chip instruction memory runs pre-loaded lighting programs—ramp, blink, and breathe effects—independently, freeing the host processor to enter deep sleep and saving system power. The 9-ball BGA package and I2C interface make it straightforward to integrate multiple LP5524 devices on one bus for multi-zone or multi-color LED architectures.

Frequently Asked Questions
How many LED channels does the LP5524TM-5 control, and what maximum current per channel can it regulate?
The LP5524TM-5 drives 9 independent LED channels with a per-channel maximum current of 25.5 mA regulated by an internal constant-current controller. Each channel's brightness is independently adjustable in 256 steps over I2C, enabling fine-grained colour mixing for RGB LEDs as well as individual white indicator control.
How does the LP5524TM-5's on-chip program memory enable autonomous LED effects without MCU involvement?
The LP5524 contains 192 bytes of on-chip instruction memory and 3 independent program execution engines. Once the host MCU loads a lighting sequence—such as a 2-second breathe ramp from 0 mA to 25.5 mA—the device executes it autonomously in a loop while the host enters deep sleep mode, saving up to several milliwatts of system power during idle notification periods.
Is the LP5524TM-5 9-ball BGA package compatible with standard SMT reflow processes for high-volume consumer assembly?
Yes. The LP5524TM-5's 9-ball BGA uses a 1.6 x 1.6 mm footprint with a 0.5 mm ball pitch, which is compatible with standard lead-free SAC305 solder paste and reflow profiles at 260°C peak temperature (JESD-609 code e1). Automated optical inspection (AOI) and X-ray verification are recommended to confirm solder joint quality given the BGA package's underside balls.
For a tri-color notification LED driven by the LP5524TM-5, how does the 256-step brightness control map to perceived colour accuracy?
Each of the 9 output channels supports 256 discrete brightness levels (8-bit resolution) with a logarithmic or linear dimming curve selectable over I2C. For an RGB LED consuming 20 mA per colour at full scale, this resolution yields steps of approximately 0.08 mA, providing smooth visual gradients and accurate colour mixing suitable for human-eye-perceived continuous transitions on smartphone notification rings.
