PCA9955TW/S911118

Overview

The PCA9955TW/S911118 is a 16-channel linear constant current LED driver with an I2C interface. It operates on a 3 V to 5.5 V supply and delivers up to 57 mA per channel. The device supports 1 MHz communication and features boost topology for driving external LEDs. It is housed in an HTSSOP-28 package and meets AEC-Q100 automotive qualification standards.

Feature Summary

Provides 16 individually controllable constant current outputs for precise LED regulation
Integrates a high-speed 1 MHz I2C interface for efficient digital control
Supports dimming functionality for adjustable brightness levels
Automotive qualified under AEC-Q100 standards for reliability

Applications

Automotive exterior lighting systems
LED backlighting applications
General-purpose LED illumination drivers

Procurement Notes

Verify the specific suffix (S911) against official NXP documentation to confirm tape-and-reel specifications. Confirm that the component meets current environmental compliance requirements such as RoHS before finalizing procurement plans.

Selection Notes

Select this component when 16 independent channels are required with linear regulation. Ensure the design accommodates the HTSSOP-28 thermal characteristics. Verify that the I2C bus speed matches the system controller capabilities.

Part Context

This part belongs to the PCA9955 series of LED drivers from NXP Semiconductors. It is designed for applications requiring multiple constant current outputs controlled via a standard serial interface, offering a compact solution for multi-segment LED arrays.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Verify that alternative components support the same 57 mA output current and 1 MHz I2C interface speed.
