PCA9532BS規(guī)格書詳情
General description
The PCA9532 is a 16-bit I2 C-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 the average current through the LED.
Features
16 LED drivers (on, off, flashing at a programmable rate)
Two selectable, fully programmable blink rates (frequency and duty cycle) between 0.591 Hz and 152 Hz (1.69 second and 6.58 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 standby current
Operating power supply voltage range of 2.3 V to 5.5 V
0 Hz 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
