1 / 51 page  LP50xx 9-, 12-Channel, 12-Bit PWM Ultra-low Quiescent Current I2C RGB LED Drivers 1 Features • Operating voltage range: – VCC range: 2.7 V to 5.5 V – EN, SDA, and SCL pins compatible with 1.8-V, 3.3-V, and 5-V power rails – Output maximum voltage: 6 V • 12 Constant-current sinks with high precision – 25.5 mA Maximum per channel with VCC in full range – 35 mA Maximum per channel when VCC ≥ 3.3 V – Device-to-device error: ±5%; channel-to- channel error: ±5% • Ultra-low quiescent current: – Shutdown mode: 1 µA (maximum) with EN low – Power-saving mode: 10 µA (typical) with EN high and all LEDs off for > 30 ms • Integrated 12-bit, 29-kHz PWM generator for each channel: – Independent color-mixing register per channel – Independent brightness-control register per RGB LED module – Optional logarithmic- or linear-scale brightness control – Integrated 3-phase PWM-shifting scheme • 3 Programmable banks (R, G, B) for easy software control of each color • 2 External hardware address pins allow connecting up to 4 devices • Broadcast slave address allows configuring multiple devices simultaneously • Auto-increment allows writing or reading consecutive registers within one transmission • Up to 400-kHz fast-mode I2C speed 2 Applications LED lighting, indicator lights, and fun lights for: • Smart speaker (with voice assistant) • Smart home appliances • Video doorbell • Electronic smart lock • Smoke and heat detector • STB and DVR • Smart router • Handheld device 3 Description In smart homes and other applications that use human-machine-interaction, high-performance RGB LED drivers are required. LED animation effects such as flashing, breathing and chasing that greatly improves user experience, and minimal system noise is essential. The LP50xx device is an 9- or 12-channel constant current sink LED driver. The LP50xx device includes integrated color mixing and brightness control, and pre-configuration simplifies the software coding process. Integrated 12-bit, 29-kHz PWM generators for each channel enable smooth, vivid color for LEDs, and eliminate audible noise.
