Overview
The PCA9635PW,112 is an NXP Semiconductors LED lighting driver IC featuring 16 independent channels. It operates on a 2.3 V to 5.5 V supply with a maximum output current of 25 mA per channel. The device supports I2C FM+ interface frequencies up to 1 MHz and functions within a temperature range of -40°C to +85°C. Packaged in a TSSOP-28 surface-mount format, it dissipates up to 400 mW. This component is currently listed as discontinued by the manufacturer.
Feature Summary
- Provides 16 individually controllable LED output channels for precise illumination management.
- Utilizes an I2C FM+ bus interface for efficient digital control and data transmission.
- Features software-programmable open-drain outputs capable of sinking 25 mA per channel.
Applications
- Backlighting systems for LCD displays
- Ambient lighting modules
- General-purpose LED indicator arrays
Procurement Notes
Verify availability status carefully as this specific part number is marked as discontinued. Confirm if alternative packaging suffixes or updated series members are available from authorized distributors. Ensure compatibility with existing PCB footprints and firmware protocols before finalizing any procurement decisions for replacement components.
Selection Notes
Select this component when designing systems requiring multiple independently controlled LED outputs via a standard I2C interface. It is suitable for applications needing moderate current drive capabilities without external transistors. Consider the TSSOP-28 package constraints and thermal dissipation requirements during the initial hardware layout phase.
Part Context
This device belongs to the PCA963x family of LED drivers designed for low-power illumination control. It serves as a bridge between microcontrollers and LED arrays, simplifying wiring and reducing pin count requirements on the host processor compared to direct GPIO driving methods.
Replacement Considerations
PCA9635PW/Q900,118 is an automotive-grade variant within the same functional family. Verify if the non-automotive version meets specific environmental reliability standards required for the target application.
