PCA9955BTW-ARD Arduino Shield allows easy integration with Arduino EVKs to evaluate the LED controller features for colour mixing, blinking and dimming LEDs. A graphical interface allows the user to easily explore the different functions of the driver to create an evaluation system.
- PCA9955BTW: 16-channel FM+ I²C-bus 57MA/20V constant-current LED driver
- Support up to four groups of LED gradation control
- Each LED channel assigned to one of four groups
- Programmable gradation time and rate for ramp-up and/or ramp-down operation
- Programmable hold-on time after ramp-up and hold-off time
- Programmable brightness current output adjustment
- Supply voltage: 3V to 5.5V, low standby current (170µA)
- 57mA / 20V output drive per channel, output current adjusts through resistor at REXT pin
- 1MHz I2C bus, output enable (/OE) pin
- HTSSOP28 plastic thermal enhanced thin shrink small outline package
