PRODUCTION DATA. LP5030, LP5036 SLVSEH1B – SEPTEMBER 2018 – REVISED JANUARY 2019 LP503x 36-, 30-Channel 12-Bit PWM Ultra-low Quiescent Current I2C RGB LED Drivers 1 1 Features 1 • 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 • 36 Constant-Current Sinks With High Precision – 25.5 mA Maximum per Channel When VCC in Full Range – 35 mA Maximum per Channel When VCC ≥ 3.3 V – Device-to-Device Error ±5%; Channel-to- Channel Error ±5% • Ultralow Quiescent Current: – Shutdown Mode: 1 µA (Maximum) When EN Low – Power Saving Mode: 12 µA (Maximum) When 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-Shifting PWM 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 • Smart Home Appliances • Video Doorbell • Electric Smart Lock • Smoke Detector • Set-Top Box • Smart Router • Handheld Devices 3 Description Efficient and high-performance LED response effects, such as blinking, breathing, and chasing, are critical to improving end-user experience in many human machine interface (HMI) applications. The LP503x device is a 30- or 36-channel constant- current-sink LED driver. The LP503x has a 29 kHz, 12-Bit PWM generator for each channel, as well as channel/module independent color mixing and intensity control, formerly called brightness control registers to enable vivid LED effects with zero audible noise. Users can benefit from the device’s ultra-low shutdown Iq Power Saving Mode, while designers will appreciate the incredibly straightforward software coding of the LP503x’s three programmable R G B banks.
