Product details
Overview
LP5562TME/NOPB from Texas Instruments is a four-channel RGBW LED driver IC with autonomous lighting pattern execution, 8-bit current control (0–25.5 mA per channel in 100-μA steps), 8-bit PWM control (256 Hz or 558 Hz), and internal SRAM program memory. It operates as a self-contained lighting controller in mobile keypad backlighting and cosmetic indicator applications.
For engineers reviewing the LP5562TME/NOPB datasheet, LP5562TME/NOPB pinout, LP5562TME/NOPB application, or LP5562TME/NOPB equivalent, key selection criteria include autonomous program execution capability, I²C-address flexibility (4 selectable addresses), low-power standby (0.2 µA), and precise current matching (±1% typical) across R/G/B/W channels.
Technical Context
The LP5562TME/NOPB integrates three independent program execution engines that load lighting sequences into on-chip SRAM and drive up to four LED channels without host MCU intervention. Each engine supports ramp, set-PWM, branch, go-to-start, and end-trigger instructions for complex timing-based effects.
It features dual clock sources - internal oscillator (±7% accuracy) or external 32-kHz crystal - enabling automatic power-save mode when LEDs are inactive. LED outputs are constant-current sinks with 60-mV typical saturation voltage and support both direct register-based PWM and engine-driven pattern generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LED Channels | 4 independent constant-current sinks (R, G, B, W) with dedicated 8-bit current and PWM registers |
| Output Current Range | 0–25.5 mA per channel in 100-μA increments; enables precise brightness calibration across color channels |
| PWM Frequency | 256 Hz or 558 Hz (selectable via PWM_HF bit); avoids audible noise while supporting smooth visual transitions |
| Current Matching | ±1% typical at 17.5 mA; ensures uniform color balance in RGBW systems without external trimming |
| Supply Current (Standby) | 0.2 µA with EN = 0 and CHIP_EN = 0; critical for battery-powered devices requiring ultra-low quiescent power |
| I²C Address Options | 4 pin-selectable addresses (ADDR_SEL0/1); allows stacking up to four LP5562TME/NOPB devices on one bus without address conflict |
| Saturation Voltage | 60 mV typical at 17.5 mA; minimizes forward-voltage headroom loss and improves efficiency with low-Vf LEDs |
Pinout & Package
LP5562TME/NOPB uses a 12-pin DSBGA package (1.648 mm × 1.248 mm, 0.4-mm pitch) with bottom-side ball layout optimized for compact mobile PCBs.

| B3 (GND) | Ground reference | Common return path for all analog/digital circuits; requires low-impedance PCB connection |
| B4 (G) | Green LED current sink output | Constant-current sink terminal for G-channel; matched to R/B/W for consistent color rendering |
| C1 (SDA) | I²C bidirectional data line | Open-drain interface compliant with standard/fast-mode I²C (up to 400 kHz) |
| C2 (SCL) | I²C clock input | Master-generated clock; timing meets JEDEC JESD88-A specification for reliable communication |
| C3 (EN/VCC) | Enable and logic supply input | 1.65–VDD V logic supply; rising edge enables device and resets internal state machines |
| C4 (R) | Red LED current sink output | Constant-current sink terminal for R-channel; shares same current accuracy and matching specs as other channels |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar RGBW LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP5569RTVT | Same 4-channel architecture but adds integrated boost converter for driving higher-Vf LEDs; larger 16-pin QFN package | Required when powering white LEDs above VDD rail (e.g., >5.5 V forward voltage); not drop-in compatible due to different pinout and power architecture | Select LP5569RTVT only if system requires boost capability; otherwise LP5562TME/NOPB offers lower cost and smaller footprint |
| PCA9633DP | 4-channel I²C LED driver with 12-bit PWM (4096 steps) but no autonomous program memory or execution engines | Suitable for simple static or host-controlled blinking; lacks self-running pattern capability and current matching spec (±3% typical) | Choose PCA9633DP for basic dimming where MCU handles all timing; LP5562TME/NOPB preferred when autonomous operation is required |
Compared with LP5569RTVT and PCA9633DP, the LP5562TME/NOPB uniquely balances autonomous lighting execution, ultra-low standby power, and compact DSBGA packaging-making it optimal for space- and energy-constrained mobile cosmetic lighting where host offload is critical.

FAQ
What is the maximum LED current supported by the LP5562TME/NOPB?
The LP5562TME/NOPB supports a maximum output current of 25.5 mA per channel (R, G, B, W), adjustable in precise 100-μA steps via I²C registers. This range is confirmed in the Electrical Characteristics table (IMAX = 25.5 mA) and applies across the full operating temperature range (−40°C to +85°C). The LP5562TME/NOPB maintains this rating with 60-mV typical saturation voltage, ensuring efficient operation even at peak current.
Does the LP5562TME/NOPB require an external crystal to operate autonomously?
No-the LP5562TME/NOPB can operate autonomously using its internal oscillator (enabled via CONFIG register bit 08h[0]), though external 32-kHz clock input (CLK_32K pin) improves timing accuracy for synchronized lighting patterns. The internal oscillator has ±7% frequency tolerance, while the external clock option enables tighter control over program execution timing. Both modes support full autonomous operation of the LP5562TME/NOPB's three program engines.
How many I²C addresses does the LP5562TME/NOPB support, and how are they configured?
The LP5562TME/NOPB supports four unique I²C slave addresses (0x30, 0x31, 0x32, 0x33) selected via two hardware pins: ADDR_SEL0 and ADDR_SEL1. These pins are sampled at power-up and determine the base address; no software configuration is needed. This allows up to four LP5562TME/NOPB devices to share a single I²C bus without address collision-critical for multi-zone lighting systems.
What is the purpose of the three program execution engines in the LP5562TME/NOPB?
The three program execution engines in the LP5562TME/NOPB enable autonomous, MCU-free execution of lighting sequences stored in on-chip SRAM. Each engine supports commands like ramp, set-PWM, branch, and go-to-start, allowing complex effects (e.g., breathing, chasing, pulsing) to run independently. Engines can be assigned to any combination of R/G/B/W channels via register 70h, and their operation is fully configurable through I²C-making the LP5562TME/NOPB ideal for offloading lighting tasks from the host processor.
Can the LP5562TME/NOPB drive both RGB and white LEDs simultaneously?
Yes-the LP5562TME/NOPB is explicitly designed as a four-channel RGBW LED driver, with dedicated current-sink outputs for red (R), green (G), blue (B), and white (W) LEDs. All four channels operate concurrently with independent 8-bit current and PWM control, enabling mixed-color effects such as RGB blending with white-point adjustment. The datasheet confirms simultaneous operation in Typical Application Diagrams and Electrical Characteristics tables.
