PCA9635PW/Q900,118

Overview

The PCA9635PW/Q900,118 is an automotive-grade LED lighting driver IC manufactured by NXP Semiconductors. It features a boost topology with sixteen independent outputs capable of delivering up to 25 mA per channel. The device operates on an I2C interface supporting frequencies from 100 kHz to 1 MHz and accepts input voltages between 2.3 V and 5.5 V. Designed for robust performance, it functions within a temperature range of -40°C to +85°C and holds AEC-Q100 qualification. The component is housed in a TSSOP-28 package.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q100 standard
• Integrated boost topology for efficient LED power management
• High-speed FM+ I2C bus interface for rapid control communication

Applications

• Automotive interior ambient lighting systems
• Vehicle exterior illumination control modules
• LED backlighting applications requiring high reliability

Procurement Notes

Verify that the specific suffix Q900 corresponds to the required automotive grade certification and packaging configuration. Confirm current lifecycle status as the component may be subject to obsolescence notices. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this variant when automotive qualification is mandatory for the application. The integrated boost topology distinguishes it from linear drivers suitable for lower voltage drops. Verify that the 25 mA output current meets the specific LED string requirements without necessitating external amplification stages.

Part Context

This part belongs to the PCA9635 series of LED drivers designed for complex lighting architectures. It provides precise control over multiple channels via a serial interface. The Q900 designation indicates compliance with automotive quality standards, differentiating it from commercial variants intended for consumer electronics.
