Product Description

DESCRIPTION:

• 16 LED drivers, each output programmable as: turn off, Open, Programmable LED brightness, Programmable Group Blur / Blink Mix with independent LED brightness
• 1MHz Fast Mode Plus is compatible with SDI with 30mA high drive capability2C bus interface to drive the high capacitive bus
•          Each LED output enables 4096 (12-bit) linear programmable brightness from full off (default) to maximum brightness
•          Can be programmed for open-drain LED output selection (the default is push-pull) 16 push-pull output (5V can absorb 25mA sink current and provide 10mA pull current), no input function
•          The output status can be programmed to change at the time of an acknowledge or stop command to update all output at the same time or byte-by-byte update output (default is “Stop command change”)
•          Low active output enable input pin, when the pin is high, the LED output can be programmed to 0, 1 or high impedance state (power-up default is high impedance state)
•          6 hardware address pins make the same I2C bus can be connected to 62 PCA9685 devices
•          The LED output frequency (all LEDs) is typically 40Hz to 1000Hz (when the oscillator is 25MHz, the prescaler register defaults to 1EH will produce a 200Hz refresh rate)
•          4 software programmable2The C bus address (an LED group call address and three LED sub call addresses) allows the device group to be addressed at any time at any time (for example, a register is used for all calls “Then I2All PCA9634 devices on the C bus can be addressed at the same time and the second register is used for three different addresses, then one-third of the bus in the device group can be addressed at the same time) Can be enabled and disabled by software2C bus address
