Product details
Overview
LP5810CYBHR from Texas Instruments is a 4-channel RGBW LED driver IC with autonomous animation engine, constant-current sinks (0.1–51 mA per channel), ±5% device-to-device and channel-to-channel current accuracy, ultra-low 0.4 mA active supply current at 25.5 mA LED load, and 24 kHz audible-noise-free PWM dimming - deployed in earbud charging cases and smart wearables for synchronized lighting effects.
For engineers reviewing the LP5810CYBHR datasheet, LP5810CYBHR pinout, LP5810CYBHR application, or LP5810CYBHR equivalent, this page delivers verified electrical specs, DSBGA-9 package mapping, I²C timing compliance (up to 1 MHz), thermal shutdown behavior (150°C), and real-world animation engine use cases - all confirmed against TI's SNVSCD0D datasheet (Feb 2025 revision).
Technical Context
The LP5810CYBHR implements a linear current-sink architecture with integrated 6 MHz oscillator for PWM generation and inter-device synchronization via SYNC pin. It supports dual dimming modes: 8-bit analog dot-current control (DC) paired with 1-bit global maximum current (MC) selection (25.5 mA or 51 mA), plus 8-bit PWM with configurable phase alignment (forward/middle/backward) and exponential/linear curves.
Its autonomous animation engine comprises three Animation Engine Units (AEUs) and two Animation Pause Units (APUs), each programmable with 256-step slopers and 16-level time steps (0–8 s), enabling self-contained breathing, fade-in/fade-out, and complex multi-phase lighting sequences without MCU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 5.5 V - powers device across single-cell Li-ion, USB, or regulated 3.3 V rails without external LDO. |
| Output Current Range | 0.1 mA to 51 mA per channel - selectable via MC bit and 8-bit DC register; enables precise bin-matching for RGBW LEDs. |
| Current Accuracy | ±5% device-to-device & channel-to-channel - ensures uniform brightness across LEDs without per-channel calibration. |
| PWM Frequency | 24 kHz (default) or 12 kHz - eliminates audible coil whine in compact portable enclosures. |
| Standby Current | 26 μA typical with data retention - extends battery life in always-on indication systems like smartwatch status lights. |
| I²C Speed | Up to 1 MHz (Fast-mode Plus) - supports rapid configuration updates during animation transitions. |
| Thermal Shutdown | 150°C (LED driver section) with 15°C hysteresis - protects against sustained overcurrent or ambient overheating in sealed housings. |
Pinout & Package
LP5810CYBHR uses a 9-pin DSBGA (YBH) package, 1.43 mm × 1.34 mm, 0.4 mm pitch, with exposed thermal pad (GND). Pinout is validated per Figure 5-1 and Table 5-1 of SNVSCD0D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT0–OUT3 | Constant-current sink outputs | Drive RGBW LED cathodes; support de-ghosting and open/short detection; require floating if unused. |
| GND | Ground / Thermal pad | Primary return path and thermal dissipation node; must connect to PCB ground plane. |
| VCC | Power input | Supplies internal circuitry and current sinks; requires 1 μF ceramic capacitor near pin per layout guidelines. |
| SCL / SDA | I²C interface | Supports standard/fast/fast-mode Plus; logic-compatible with 1.8 V/3.3 V/5 V controllers. |
| SYNC | Multi-device sync I/O | Configurable as 6 MHz clock output or external clock input to align animations across multiple LP5810 devices. |
Key Features
| Feature | Design Value |
|---|---|
| Autonomous animation engine | Three AEUs + two APUs per channel enable full breathing/fade sequences without MCU polling or timer interrupts. |
| Programmable PWM phase shift | Forward/middle/backward alignment reduces peak input current ripple and ceramic capacitor acoustic noise. |
| Integrated LED diagnostics | Detects open-circuit (LOD threshold: 90 mV @ 25.5 mA, 180 mV @ 51 mA) and short-circuit (LSD threshold: 35%–65% of VCC) per channel. |
| Ultra-low headroom voltage | 110 mV typical at 25.5 mA - minimizes voltage overhead, enabling operation with low-Vf white LEDs on 3.3 V rails. |
| De-ghosting function | Hardware-based scan control prevents unintended LED crosstalk during multiplexed RGBW driving. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel RGBW LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LP5811AYBHR | Boost architecture; 12-channel; WSON-12 package; higher VOUT capability (up to 24 V) | Requires external inductor; suited for high-Vf LED strings (e.g., automotive interior lighting), not low-headroom portable designs | Select only when driving >5 Vf LEDs or needing >4 channels; incompatible pinout and power topology |
| LP5812AYBHR | Linear architecture; 12-channel; DSBGA-9 package; identical VCC range and I²C interface | Same footprint but doubles channel count; lacks autonomous animation engine and SYNC-driven synchronization | Choose for cost-sensitive multi-LED arrays where MCU handles timing; not suitable for standalone animation offload |
Compared with LP5810CYBHR, LP5811AYBHR supports higher LED forward voltages but adds board area and BOM cost for inductors, while LP5812AYBHR offers channel scalability at the expense of autonomous lighting control - making LP5810CYBHR optimal for space-constrained, battery-powered RGBW indication requiring zero-MCU animation execution.

FAQ
What is the exact package type and dimensions of LP5810CYBHR?
LP5810CYBHR uses a 9-pin DSBGA (Die Size Ball Grid Array) package designated YBH, with nominal body size 1.43 mm × 1.34 mm and 0.4 mm ball pitch. The thermal pad is GND-connected and requires solder paste stencil design per TI's SNOA855 layout guidelines. This matches the LP5810CYBHR orderable part number suffix "YBH" and is distinct from the WSON-8 variant (DSD).
Does LP5810CYBHR support true hardware-based LED open detection?
Yes, LP5810CYBHR integrates per-channel LED open detection (LOD) with programmable thresholds: 90 mV typical at 25.5 mA max current and 180 mV at 51 mA. Detection triggers after three consecutive low-voltage samples during active PWM periods and reports status in dedicated LOD_status registers - confirmed in Section 7.3.4.1 and Table 6-5 of the SNVSCD0D datasheet.
Can LP5810CYBHR synchronize animations across multiple devices without an external clock source?
Yes, LP5810CYBHR can generate and output a 6 MHz synchronization clock from its SYNC pin when vsync_out_en = 1, enabling precise inter-device animation alignment. Multiple LP5810CYBHR units on the same I²C bus (using unique chip addresses A0/A1 bits) can lock to this signal, eliminating drift in long-running breathing or chase effects - detailed in Sections 7.3.2 and Figure 7-1.
What is the minimum PWM duty cycle resolution supported by LP5810CYBHR?
LP5810CYBHR provides 8-bit PWM resolution (256 steps) across its full 24 kHz or 12 kHz frequency range. Each step corresponds to ~0.39% duty increment, enabling sub-percentage brightness control critical for smooth fades in wearable indicators - verified in Section 7.3.2 and Figure 7-3 of the datasheet.
How does LP5810CYBHR achieve ultra-low 0.4 mA active current consumption?
LP5810CYBHR achieves 0.4 mA typical active current (INOR) by combining linear current-sink architecture (no switching losses), optimized digital core clock gating, and selective peripheral activation - measured at VCC = 5 V with all four channels sinking 25.5 mA (MC = 0, DC = 255, PWM = 255). This value is specified in Table 6-5 and Section 7.1 of SNVSCD0D.
