PCA9531D,112

Overview

The PCA9531D,112 is an NXP Semiconductors integrated circuit classified as a linear LED driver. It operates via an I2C interface and provides eight output channels with a maximum sink current of 25 mA per channel. The device supports a supply voltage range from 2.3 V to 5.5 V and functions within a temperature range of -40°C to +85°C. It is housed in a 16-SOIC package.

Feature Summary

Linear LED driver topology for backlight applications
I2C bus interface compatibility
Eight independent output channels

Applications

Backlight control systems

Procurement Notes

Verify the specific suffix

Selection Notes

Confirm that the application requires linear dimming rather than PWM control. Ensure the system design accommodates the 25 mA per channel limit and the 16-SOIC package dimensions. Verify I2C address configuration if multiple devices are used on the same bus.

Part Context

This component belongs to the PCA9531 series of LED drivers manufactured by NXP USA Inc. It is designed specifically for managing LED brightness in display backlights through linear current regulation controlled via serial communication protocols.
