Key Features
- Drives an 11×18 LED matrix with 198 individual segments, enabling high-density dot-matrix display panels in a single IC for wearables, industrial indicators, and smart appliances
- Dual dimming control combining 8-bit analog current adjustment and 8-/16-bit PWM dimming per LED channel delivers up to 16-bit effective resolution for smooth, flicker-free visual transitions
- Serial data input interface (SPI-compatible) reduces microcontroller pin count to 3–4 wires regardless of 198 LED channels, simplifying firmware integration and PCB routing
- QFN-40 (LCC 40-pin, 4×4 mm body) package provides a compact, thermally efficient footprint ideal for space-constrained wearable and consumer display designs
Applications
PLP5860RKPR is designed for high-density dot-matrix LED displays in smartwatches, fitness bands, and consumer electronics where 198 individually addressable segments must fit within a minimal footprint. Its 8-/16-bit PWM dimming enables smooth brightness transitions in notification displays, ambient light indicators, and graphic icon panels driven directly by a microcontroller over a 3-wire serial interface. The device is also well-suited for industrial HMI panels and medical device indicator arrays where precise per-LED current control and multiplexed drive reduce BOM cost compared to discrete driver arrays.

Frequently Asked Questions
How many LED segments can PLP5860RKPR drive, and what display resolution does that enable?
PLP5860RKPR drives up to 198 individual LED segments arranged in an 11×18 dot-matrix configuration. This resolution is sufficient for rendering alphanumeric characters, simple icons, and scrolling text in small wearable displays, with each segment independently addressable via the serial interface for full graphical flexibility within an 11-row by 18-column grid.
What dimming resolution does PLP5860RKPR provide, and how does 16-bit PWM dimming improve display quality?
PLP5860RKPR supports 8-bit analog current dimming combined with 8-bit or 16-bit PWM dimming per LED channel. At 16-bit PWM resolution, the device achieves 65,536 discrete brightness steps per LED, producing visually flicker-free gradients and smooth fade effects at frame rates above 60 Hz. This combination is critical for smartwatch notification displays and ambient light animations where the human eye perceives quantization artifacts below roughly 10-bit effective resolution.
How does PLP5860RKPR's serial interface simplify firmware integration compared to a parallel LED driver?
PLP5860RKPR uses a serial data input (SPI-compatible, JESD-30: S-PQCC-N40) interface that transfers all 198 channel data over 3 to 4 signal wires regardless of the total LED count. A parallel LED driver for 198 channels would require 14 to 20 GPIO lines plus address decoding logic, whereas PLP5860RKPR reduces the microcontroller pin commitment to 4 SPI pins—freeing GPIO resources and eliminating multi-chip bus arbitration in resource-constrained embedded systems.
For a smartwatch display requiring 198 independently dimmable LEDs, how does PLP5860RKPR compare to using multiple smaller LED driver ICs?
Covering 198 LED channels with discrete 16-channel drivers would require at least 13 separate ICs, each consuming roughly 16 mm² in TSSOP-20 packages—totaling over 200 mm² of PCB area. PLP5860RKPR consolidates all 198 channels into a single QFN-40 package with an approximately 16 mm² footprint, reducing area by more than 12×. It also eliminates inter-driver synchronization firmware and the voltage mismatch risks of daisy-chaining 13 devices on a shared I2C or SPI bus.
