PCA9685BS规格书详情
General description
The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for LCD Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 40 Hz to 1000 Hz with a duty cycle that is adjustable from 0 to 100 to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency.
• The PCA9685 allows staggered LED output on and off times to minimize current surges. The on and off time delay is independently programmable for each of the 16 channels. This feature is not available in PCA9635.
• The PCA9685 has 4096 steps (12-bit PWM) of individual LED brightness control. The PCA9635 has only 256 steps (8-bit PWM).
• When multiple LED controllers are incorporated in a system, the PWM pulse widths between multiple devices may differ if PCA9635s are used. The PCA9685 has a programmable prescaler to adjust the PWM pulse widths of multiple devices.
• The PCA9685 has an external clock input pin that will accept user-supplied clock (50 MHz max.) in place of the internal 25 MHz oscillator. This feature allows synchronization of multiple devices. The PCA9635 does not have external clock input feature.
• Like the PCA9635, PCA9685 also has a built-in oscillator for the PWM control.
However, the frequency used for PWM control in the PCA9685 is adjustable from about 40 Hz to 1000 Hz as compared to the typical 97.6 kHz frequency of the PCA9635. This allows the use of PCA9685 with external power supply controllers. All bits are set at the same frequency.
• The Power-On Reset (POR) default state of LEDn output pins is LOW in the case of PCA9685. It is HIGH for PCA9635.
PCA9685BS属于集成电路(IC) > LED 驱动器。恩智浦半导体公司制造生产的PCA9685BSLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列,可通过标称固定电压的电源为负载(通常为发光二极管)提供电流,并且电流可控。它与用于电压调节的类似产品的主要区别在于,这类器件提供较低的反馈电压(以提高系统能效),而且通常可对器件工作点进行外部控制,可在照明应用中用于实现调光功能。
