Product details

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.

Frequently asked questions

What is the I2C address range for the PCA9531PW,118?

The I2C address is set by three hardware address pins, giving eight possible addresses from 0x60 to 0x67. This allows up to eight drivers on the same bus without conflict.

Can the PCA9531PW,118 drive high-power LEDs?

No — each channel is rated for 25 mA maximum. For high-power LEDs requiring 100 mA or more, you would need an external transistor or MOSFET stage driven by the PCA9531's open-drain outputs.

Is the PCA9531PW,118 a drop-in replacement for the base PCA9531?

Yes, the PCA9531PW,118 is the tape-and-reel variant of the PCA9531 in the 16-TSSOP package. The die and pinout are identical; the 'PW' suffix indicates the TSSOP package, and ',118' denotes reel packaging. No board layout change is needed.
