Overview
The PCA9633DP1,118 is a 4-bit voltage-switch LED driver IC manufactured by NXP Semiconductors. It features four independent output channels capable of sourcing up to 25 mA per channel and sinking up to 100 mA. The device operates on an I²C interface supporting frequencies from 100 kHz to 1 MHz. It functions within a supply voltage range of 2.3 V to 5.5 V and supports PWM dimming. Packaged in an 8-TSSOP format, it is designed for applications requiring precise LED brightness control.
Feature Summary
- Four-channel independent LED drive capability with high sink current capacity
- I²C bus interface supporting standard and fast mode operations
- Integrated PWM dimming functionality for precise brightness adjustment
Applications
- LED backlighting systems
- General LED illumination drivers
- RGB/RGBW LED color mixing controllers
Procurement Notes
Verify the specific suffix '118' against official NXP documentation to confirm tape and reel packaging specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm compatibility with your design's electrical constraints and environmental operating conditions.
Selection Notes
Select this component when a low-pin-count solution is required for multi-channel LED control. It is suitable for designs needing direct MCU interfacing via I²C without additional logic gates. Consider the thermal dissipation limits of the TSSOP-8 package if driving multiple channels at maximum current simultaneously.
Part Context
This part belongs to the PCA9633 series of LED controllers. It shares functional similarities with the PCA9632 but offers specific interface speed optimizations. The DP1 designation indicates the TSSOP-8 package variant, distinguishing it from other package options like HVSON or SOIC found within the broader family.
Replacement Considerations
The PCA9632 serves as a compatible alternative within the same product family. Verify pinout compatibility and register mapping before substitution. Ensure that the replacement part number matches the required package type and interface speed specifications.
