PCA9624PW,112

Overview

The PCA9624PW,112 is an 8-channel LED driver IC manufactured by NXP USA Inc., designed for backlight applications. It operates within a supply voltage range of 2.3V to 5.5V and supports output voltages up to 40V. The device features linear PWM dimming with a frequency range of 100kHz to 1MHz. Each channel provides an output current of 100mA. It utilizes a 24-TSSOP package (4.40mm wide) and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Provides eight independent channels for driving LEDs with integrated linear PWM dimming control.
• Supports high-voltage outputs up to 40V via open-drain NAND FET switches.
• Enables flexible bus addressing through software-configurable sub-addressing capabilities.

Applications

• Backlight systems
• General LED lighting

Procurement Notes

Verify the specific suffix '112' against official NXP documentation to confirm the tube packaging format, as this variant differs from the '118' reel version. Confirm component status, as some sources indicate end-of-life or discontinuation for this specific part number. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when eight individually controllable LED channels are required with linear PWM dimming capabilities. It is suitable for designs needing support for higher load voltages up to 40V while maintaining low supply voltage operation. Consider the 24-TSSOP package constraints and thermal dissipation characteristics relative to the expected current load per channel.

Part Context

This component belongs to the PCA962x series of I²C-bus controlled LED drivers. It shares functional similarities with other members like the PCA9626 but offers a specific channel count and voltage configuration tailored for standard backlighting tasks. The device integrates internal switching elements to simplify external circuit design.
