PCA9624PW,118

Overview

The PCA9624PW,118 is an NXP USA Inc. LED driver IC featuring eight linear PWM dimming outputs with a maximum current of 100mA per channel. It operates on a supply voltage range of 2.3V to 5.5V and supports output voltages up to 40V. The device utilizes a 100kHz to 1MHz I2C interface for control and is housed in a 24-TSSOP package. Designed for backlight applications, it functions within a temperature range of -40°C to 85°C.

Feature Summary

• Eight independent linear PWM channels for precise LED brightness control
• Integrated internal switches for direct LED driving capability
• I2C-bus interface for efficient serial communication and configuration

Applications

• LCD backlight systems
• General indicator lighting
• Portable electronic displays

Procurement Notes

Verify component status as the PCA9624 series may be discontinued or subject to lifecycle changes. Confirm package integrity and RoHS compliance against specific manufacturing dates. Cross-reference official NXP documentation for any pin-compatible alternatives if sourcing new production units.

Selection Notes

Select this component when eight individually controllable LED channels are required with moderate current drive capabilities. Ensure the application voltage does not exceed the 40V output limit. Verify that the I2C bus speed requirements align with the specified frequency range for reliable data transmission.

Part Context

This part belongs to the PCA9624 family of LED controllers from NXP Semiconductors. It is designed to replace older discrete LED driving solutions by integrating multiple channels into a single compact surface-mount package, simplifying PCB layout and reducing component count in display driver circuits.

Replacement Considerations

PCA9955BTWJ is listed as a manufacturer-recommended substitute. Verify functional equivalence regarding output current and interface compatibility before implementation.
