PCA9633DP2,118

Overview

The PCA9633DP2,118 is a discontinued 4-bit I²C-bus LED driver manufactured by NXP USA Inc. It features four open-drain outputs capable of sinking up to 25 mA per channel and 100 mA total, operating within a supply voltage range of 2.3 V to 5.5 V. The device supports I²C clock frequencies from 100 kHz to 1 MHz and functions across an extended temperature range of -40°C to +85°C. Packaged in a 10-TSSOP surface-mount format, it integrates internal power-on reset and noise filtering for reliable operation.

Feature Summary

• Four independent open-drain output channels designed for direct LED driving
• I²C interface supporting standard and fast mode clock frequencies
• Integrated internal power-on reset mechanism ensuring defined initial states
• Input noise filtering on SCL and SDA lines to enhance signal integrity

Applications

• Backlight control systems
• General-purpose indicator lighting
• Embedded status indication circuits

Procurement Notes

This component is officially marked as No Longer Manufactured by NXP USA Inc. Procurement must focus on verifying the authenticity of remaining stock from authorized distributors or third-party suppliers. Buyers should confirm the specific manufacturing date code and storage conditions prior to acquisition, as availability is limited to existing inventory rather than new production runs.

Selection Notes

Engineers requiring this specific package and pinout must evaluate the discontinuation status before finalizing designs. If the 10-TSSOP form factor is mandatory, alternative sourcing strategies such as long-term stocking agreements with certified distributors are necessary. For new developments, consider evaluating equivalent active components that offer similar electrical characteristics but ensure long-term supply chain stability.

Part Context

The PCA9633 series represents NXP's low-power LED driver solutions utilizing the I²C bus protocol. This specific variant belongs to the family of controllers designed to simplify LED management in space-constrained applications. While the DP2 suffix denotes the 10-TSSOP package, other variants like the PCA9633DP1 utilize an 8-TSSOP package, sharing identical core functionality and electrical specifications.
