Frequently Asked Questions
What is the LP3944ISQ/NOPB and what does it do?
The LP3944ISQ/NOPB is an 8-channel LED driver from Texas Instruments controlled via I2C. It allows up to 8 LEDs to be individually switched on/off or placed in one of two programmable blink groups. Each channel sinks up to 25mA, making it suitable for indicators and small displays in portable and embedded systems.
What supply voltage does the LP3944ISQ/NOPB require?
The LP3944ISQ/NOPB operates from a 1.8V to 5.5V supply, making it compatible with both 3.3V and 5V logic systems. This wide range allows it to interface directly with modern microcontrollers and SoCs without level-shifting.
What package is the LP3944ISQ/NOPB and how many pins does it have?
It comes in a WSON-10 package (10-pin, 3mm × 3mm), a small leadless SMD package suited for compact board layouts. The 10-pin footprint provides all I2C, power, and LED output connections.
What are suitable alternates for the LP3944ISQ/NOPB?
The PCA9551 (NXP) is a pin-compatible 8-bit I2C LED driver with similar blink control. The LP3943 from Texas Instruments is also closely related, offering 16-channel output for higher-density LED arrays. Both operate on comparable voltage rails and I2C interfaces.
Is the LP3944ISQ/NOPB RoHS compliant and what is its lifecycle status?
Yes, the /NOPB suffix indicates the device is lead-free and RoHS compliant. The LP3944ISQ/NOPB is in active production status at Texas Instruments, ensuring continued availability and supply chain support.
