Overview
The PCA9632DP1,118 is a 4-bit Fast-mode Plus (Fm+) I²C-bus low-power LED driver manufactured by NXP Semiconductors. It features four independent LED outputs with programmable open-drain or totem-pole configurations. The device supports an input voltage range of 2.3 V to 5.5 V and delivers up to 25 mA sink current per channel. It operates within a temperature range of -40°C to +85°C and utilizes a TSSOP8 surface-mount package.
Feature Summary
- Fast-mode Plus I²C interface supporting frequencies up to 1 MHz for efficient bus communication.
- Independent 8-bit PWM controllers providing 256 brightness levels for each LED output.
- Programmable output drivers configurable as open-drain or totem-pole for flexible circuit integration.
Applications
- Red/Green/Blue/Amber (RGBA) color mixing applications
- Backlight control systems
- LED lighting driver circuits
Procurement Notes
Verify the specific suffix DP1 against the official NXP datasheet to confirm the TSSOP-8 package variant. Ensure compatibility with system voltage requirements between 2.3 V and 5.5 V. Confirm that the 1 MHz I²C speed aligns with the host controller's capabilities. Check for RoHS compliance status in the latest product material declaration before finalizing procurement.
Selection Notes
Select this component when a low-power solution with high-speed I²C communication is required. The PCA9632 offers significantly lower power consumption compared to previous generations like the PCA9633. It is suitable for designs needing precise individual LED dimming without external microcontrollers for PWM generation. Consider the TSSOP8 package constraints for PCB layout.
Part Context
This part belongs to the PCA9632 series of 4-bit Fm+ I²C-bus LED drivers. It serves as a low-power alternative to the PCA9633, offering reduced power dissipation while maintaining similar functionality. The series is designed for applications requiring multiple independently controllable LED channels with software-configurable addressing and grouping capabilities.
Replacement Considerations
PCA9632DP2Z is listed as a direct substitute for the discontinued PCA9632DP2 variants, though package differences exist. Verify pinout and electrical specifications against the target application requirements before substitution.
