PCA9532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
