Overview
The PCA9552PW,118 is a 16-bit LED driver IC featuring an I2C interface operating at 400 kHz. It provides 16 open-drain outputs with a maximum sink current of 25 mA per channel and 6.5 mA low-level output current. The device supports adjustable voltage output and utilizes Boost or Buck topology. It operates within a supply voltage range of 2.3 V to 5.5 V and functions between -40°C and +85°C. Packaged in a 24-TSSOP, it dissipates up to 400 mW.
Feature Summary
- Integrates 16 independent channels for precise LED control via I2C communication.
- Supports programmable dimming and blinking functions without external components.
- Includes internal power-on reset and noise filters for stable operation.
Applications
- LED lighting driver systems
- General-purpose LED indication circuits
- I2C bus peripheral expansion
Procurement Notes
Verify the complete part number including the suffix ,118 to ensure correct packaging configuration. Confirm RoHS compliance status and check for specific ordering codes if reel quantities are required. Cross-reference manufacturer datasheets for pinout accuracy before integration into PCB designs.
Selection Notes
Select this component when 16-channel LED control is necessary with minimal microcontroller overhead. The I2C interface reduces pin count compared to parallel drivers. Ensure the application voltage falls within the 2.3 V to 5.5 V range and that thermal dissipation requirements fit the TSSOP-24 package constraints.
Part Context
This part belongs to the PCA9552 series of LED controllers from NXP Semiconductors. It is designed for applications requiring efficient LED management through serial interfaces. The family focuses on reducing system complexity by integrating drive capabilities directly into the controller.
Replacement Considerations
CAT9532YI-T2 is listed as a similar substitute part number available from onsemi.
