NXP PCA9532PW,112 发光二极管驱动器, 16输出, 2.3V-5.5V输入, 400kHz开关, 200mA输出, TSSOP-24
The is a 16-bit I²C-bus LED Dimmer optimized for dimming LEDs in 256 discrete steps for red, green and blue RGB colour mixing and back light applications. The LED dimmer 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 >100Hz 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. To blink LEDs at periods greater than 1.69second the bus master MCU, MPU, DSP, chip set, etc. must send repeated commands to turn the LED on and off as is currently done when using normal I/O expanders like the semiconductors.
All input and output pins are protected against ESD under normal handling. When handling ensure that the appropriate precautions are taken.
