DESCRIPTION
The PCA9532 is a 16-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.
The PCA9532 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 (> 100 Hz) that the blinking cannot be seen and then using the duty cycle to vary the amount of time the LED is on and thus th average current through the LED.FEATURES
•16 LED drivers (on, off, flashing at a programmable rate)
•2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.625 and 160 Hz (6.4 seconds and 6.25 milliseconds)
•256 brightness steps
•Input/outputs not used as LED drivers can be used as regular GPIOs
•Internal oscillator requires no external components
•I2C-bus interface logic compatible with SMBus
•Internal power-on reset
•Noise filter on SCL/SDA inputs
•Active-LOW reset input
•16 open drain outputs directly drive LEDs to 25 mA
•Controlled edge rates to minimize ground bounce
•No glitch on power-up
•Supports hot insertion
•Low stand-by current
•Operating power supply voltage range of 2.3 V to 5.5 V
•0 to 400 kHz clock frequency
•ESD protection exceeds 2000 V HBM per JESD22-A114, 150 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
•Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
•Packages offered: SO24, TSSOP24, HVQFN24 -
