... Packages offered: SO8, TSSOP8 DESCRIPTION The PCA9533 is a 4-bit I@C & SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications. The PCA9533 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The LED brightness is controlled by setting the blink rate high enough (> ...

... The last bit of the address byte defines the operation to be performed. When set to logic 1 a read is selected while a logic 0 selects a write operation. CONTROL REGISTER Following the successful acknowledgement of the slave address, the bus master will send a byte to the PCA9533 which will be stored in the Control Register ...

... When power is applied internal Power On Reset holds DD the PCA9533 in a reset state until V has reached V DD point, the reset condition is released and the PCA9533 registers are initialized to their default states, with all outputs in the off state. 2 CHARACTERISTICS OF THE I C-BUS 2 The I C-bus is for 2-way, 2-line communication between different ICs or modules ...

... Programming example The following example will show how to set LED0 and LED1 off. It will set LED2 to blink at 1 Hz, 50% duty cycle. LED3 will be set to be dimmed at 25% of their maximum brightness (duty cycle = 25%). PCA9533/01 is used in this example. Table 1. Start PCA9533 address PSC0 subaddress + auto-increment ...
