The PCA9633D16,112 can support I2C bus frequencies up to 400 kHz.
To ensure proper power-up and initialization, the VCC pin should be powered up before the VBAT pin, and the device should be reset by pulling the RESET pin low for at least 1 ms.
The internal oscillator on the PCA9633D16,112 is used to generate the clock signal for the device's internal logic and can be used as a clock source for the PWM outputs.
No, the PCA9633D16,112 is not designed to drive inductive loads such as relays or solenoids. It is intended for use with resistive or capacitive loads such as LEDs or LCD backlights.
The PCA9633D16,112 can be configured to operate in different modes by writing to the MODE1 and MODE2 registers. The specific mode is determined by the values written to these registers.
