Overview
The PCA9629PW,118 is a 16-channel LED driver IC manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.3 V to 5.5 V and supports an I2C interface with frequencies from 100 kHz to 1 MHz. The device features a TSSOP-28 package and provides bipolar or unipolar motor drive capabilities alongside LED control. It functions across an extended temperature range of -40°C to +85°C.
Feature Summary
- Supports both bipolar and unipolar motor driving configurations
- Integrates 16 independent output channels for LED control
- Enables serial data input via standard I2C bus protocol
Applications
- LED lighting systems requiring multi-channel control
- Motor driver circuits utilizing bipolar or unipolar topologies
- Embedded systems interfacing with I2C peripherals
Procurement Notes
Verify the specific suffix '118' against official NXP documentation to confirm tape and reel packaging specifications. Ensure the component matches the TSSOP-28 footprint requirements for your PCB layout. Cross-reference the datasheet revision date to validate electrical characteristics before integration into production designs.
Selection Notes
Select this component when a single IC must manage multiple LEDs and potentially low-power motors. The integrated I2C interface reduces pin count compared to parallel drivers. Verify that the 25 mA output current capability aligns with the load requirements of your specific application design.
Part Context
This part belongs to the PCA962x series of LED drivers from NXP. It shares functional similarities with other members like the PCA963x series but differs in specific channel counts and interface speeds. It serves as a bridge between microcontrollers and high-current loads in compact form factors.
Replacement Considerations
Check NXP's official obsolescence notices for direct substitutes. Potential alternatives may include newer revisions within the PCA962x family or compatible drivers from other manufacturers if pin compatibility is required.
