Description

Product Overview

The LP5562TME/NOPB from Texas Instruments is a 4-channel RGB/White LED driver with internal program memory and independent channel control in a DSBGA-12 package. Each channel provides 8-bit PWM and 8-bit current control (0-25.5mA in 100uA steps), with three programmable execution engines for autonomous lighting patterns.

Key Specifications

Number of Channels 4 (R, G, B, White)
LED Current Range 0 to 25.5 mA per channel (100uA steps)
PWM Resolution 8-bit per channel
Current Matching 1% (typical)
Output Saturation Voltage 60 mV (typical)
Supply Voltage 2.7 V to 5.5 V
Interface I2C (up to 400kHz)
Program Engines 3 independent
Operating Temperature -40C to +85C

Features

  • 4 independently programmable LED channels with 8-bit PWM and 8-bit current control
  • Three program execution engines for autonomous lighting patterns
  • Internal SRAM program memory for pattern storage
  • 60mV typical saturation voltage minimizes headroom requirement
  • 1% current matching between channels for consistent color
  • Automatic power-save mode with external clock

Applications

  • RGB LED lighting and effects in mobile devices
  • Indicator and notification LED control
  • Wearable device RGB illumination
  • Portable electronics ambient lighting

The LP5562TME/NOPB from Texas Instruments is a 4-channel RGB or White LED driver with internal program memory in an ultra-compact DSBGA-12 (1.55×1.55mm) package. Each of the four channels provides independent 8-bit current control (0 to 25.5mA in 100uA steps) and 8-bit PWM control. Current matching between channels is 1% typical with 60mV saturation voltage. Three program execution engines with flexible instruction sets allow autonomous lighting pattern execution without host processor intervention. Programs are stored in internal SRAM. The device communicates via I2C at up to 400kHz, and enters automatic power-save mode when an external clock is provided.

The LP5562TME/NOPB integrates four independent current sinks with PWM modulation and three program execution engines. (1) Current Control: Each channel has an 8-bit current DAC that sets the maximum LED current from 0 to 25.5mA in 100uA steps. The current sink topology allows common-anode LED connection. (2) PWM Control: An 8-bit PWM modulator on each channel controls the duty cycle, enabling 256 brightness levels. The combination of current and PWM control provides over 65,000 color combinations. (3) Program Engines: Three independent execution engines can simultaneously run lighting programs stored in the 48-entry SRAM. Each engine has its own program counter and can control one or more channels with ramp, branch, and delay instructions. (4) I2C Interface: The host writes channel settings and programs via the I2C interface at up to 400kHz. Once programmed, the engines operate autonomously. (5) Power Save: When an external clock is provided on the CLK pin, the device synchronizes its internal oscillator and enters power-save mode during idle periods.
