Frequently Asked Questions
What is the LP5521TMX/NOPB and what does it do?
The LP5521TMX/NOPB is a 3-channel RGB LED driver IC from Texas Instruments. It provides independent PWM-controlled current sources for red, green, and blue LEDs, with each channel supporting 5mA to 25.5mA output current in 5-bit steps. It communicates via I2C and includes an internal programmable engine for autonomous LED animation without CPU involvement.
What are the key electrical specifications of the LP5521?
The LP5521 operates from a supply voltage of 2.7V to 4.5V, making it suitable for single-cell Li-Ion battery applications. Each of its 3 LED channels supports up to 25.5mA current with 5-bit (32-step) resolution. The device uses a standard I2C interface (up to 400kHz) and is available in a compact DSBGA package with very low standby current consumption.
What applications is the LP5521TMX/NOPB best suited for?
The LP5521TMX/NOPB is ideal for portable and battery-powered devices including smartphones, wearables, wireless earbuds, and IoT nodes that need RGB LED status indicators. Its autonomous programmable engine reduces CPU load for LED animations. It is also used in industrial front-panel indicators and medical devices requiring accurate, repeatable color mixing via I2C control.
How do I communicate with the LP5521 in my design?
The LP5521 uses a standard I2C serial interface operating at up to 400kHz (Fast Mode). It has a 7-bit I2C address that can be configured via the ADDR pin. You write to its registers to set LED current levels, enable PWM, and load programs into the three internal execution engines for autonomous LED sequencing.
Where can I buy the LP5521TMX/NOPB and is it in stock?
The LP5521TMX/NOPB can be purchased through FindMyChip, which aggregates stock from authorized distributors worldwide. Submit a quote request with your required quantity and target price, and our team will source the part and respond via email or WhatsApp, typically within one business day.
