The PCA9634PW,118 can sink or source up to 25mA per output pin, and up to 100mA total for all outputs combined.
The PCA9634PW,118 can be configured for I2C or SMBus interface by setting the A0 and A1 address pins. For I2C, A0 and A1 should be connected to VCC or GND. For SMBus, A0 should be connected to VCC and A1 should be connected to GND.
The reset pin (RST) is an active-low input that resets the PCA9634PW,118 to its default state. When the RST pin is pulled low, the device resets and all outputs are set to a high-impedance state.
The PCA9634PW,118 can be programmed to control the brightness of LEDs by using the I2C or SMBus interface to set the output voltage and current of each channel. The device also has a built-in PWM generator that can be used to control the brightness of LEDs.
The PCA9634PW,118 operates from a supply voltage range of 2.3V to 5.5V.
