8-channel I2C LED driver for backlight and indicator control
The PCA9531PW,118 is a linear LED driver from NXP that controls eight independent LED channels via an I2C bus. Dimming is handled through the I2C interface, so you can set brightness per channel without extra PWM pins on the host controller. The supply range of 2.3 V to 5.5 V covers 3.3 V and 5 V logic rails commonly found in industrial and consumer designs.
The 25 mA per-channel limit means it drives standard indicator LEDs directly. For high-power LEDs requiring hundreds of milliamps, you would need an external transistor stage — the internal switch is rated only for this current level.
The 16-TSSOP package is a common industry format, so lead times are typically aligned with NXP's standard production cycle. Confirm current lead time and pricing at quote time through the RFQ process.
