PCA9634PW,118 Description

Short technical summary and product information.

The PCA9634PW,118 is an 8-bit LED driver from NXP Semiconductors designed for Red/Green/Blue/Amber (RGBA) color mixing applications. It features an I2C-bus interface for control and offers individual 8-bit resolution PWM controllers for each of the 8 LED outputs, operating at 97 kHz. Additionally, a group PWM controller with a fixed frequency of 190 Hz allows for simultaneous dimming or blinking of all LEDs.

 

Each LED output can be programmed for various states including off, on, or controlled by either the individual or group PWM controllers. The output driver is configurable as open-drain with a 25 mA current sink capability or totem-pole with 25 mA sink and 10 mA source capability at 5V. The device operates within a supply voltage range of 2.3 V to 5.5 V, with outputs tolerant to 5.5 V.

 

This LED driver is suitable for direct connection to LEDs (up to 25 mA, 5.5 V) or can be used with external drivers for higher current or voltage LEDs. It supports Fast-mode Plus (Fm+) I2C communication, allowing for higher bus frequencies up to 1 MHz and denser bus operation. The PCA9634PW,118 is packaged in a 20-TSSOP and is surface-mounted. It is optimized for backlight applications.
