PCA9624BS,118

Overview

The PCA9624BS,118 is an NXP LED driver IC featuring eight linear PWM outputs with a 100mA current rating 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 an I2C interface operating between 100kHz and 1MHz for control. Packaged in a 24-HVQFN format, it is designed for backlight applications within a -40°C to 85°C temperature range.

Feature Summary

• Eight independent linear PWM channels for precise LED brightness control
• Integrated internal switches supporting high-voltage loads up to 40V
• I2C-bus interface compatible with standard and fast-mode operations

Applications

• LCD panel backlighting systems
• General-purpose LED illumination control
• Industrial display modules

Procurement Notes

Verify the specific suffix 'BS' against official documentation to confirm the HVQFN package variant. Confirm component status as discontinued or active through authorized distributors. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.

Selection Notes

Select this component when eight individually addressable LED channels are required with high voltage tolerance. The linear PWM architecture suits applications prioritizing simplicity over complex digital dimming. Verify that the 100mA per-channel limit meets the target LED load specifications.

Part Context

This part belongs to the PCA9624 family of LED controllers from NXP Semiconductors. It provides a compact solution for managing multiple LEDs via a serial bus. The BS suffix indicates the specific plastic leadless chip carrier package configuration used for surface-mount assembly.

Replacement Considerations

PCA9624PW,118 is a documented substitute offering identical functionality in a TSSOP-24 package.
