NXP
The PCA9685PW,112 is a 16-channel 12-bit PWM FM + I²C-bus LED Controller optimized for 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 24 to 1526Hz 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. Each LED output can be off or on (no PWM control) or set at its individual PWM controller value. The LED output driver is programmed to be either open-drain with a 25mA current sink capability at 5V or totem pole with a 25mA sink, 10mA source capability at 5V. The PCA9685 operates with a supply voltage range of 2.3 to 5.5V and the inputs and outputs are 5.5V tolerant. 16 LED drivers 1MHz Fast-mode Plus compatible I²C-bus interface LED output frequency (all LEDs) typically varies from 24 to 1526Hz Sixteen totem pole outputs with software programmable open-drain LED outputs selection 6 Hardware address pins allow 62 PCA9685 devices to be connected to the same I²C-bus Toggling OE allows for hardware LED blinking Software Reset feature (SWRST General Call) allows the device to be reset through the I²C-bus 25MHz typical internal oscillator requires no external components External 50MHz (maximum) clock input Internal power-on reset Noise filter on SDA/SCL inputs Edge rate control on outputs No output glitches on power-up Supports hot insertion Low standby current 5.5V Tolerant inputs ESD protection Latch-up testing is done to JEDEC standard JESD78 which exceeds 100mA Device Topology: - No. of Outputs: 16Outputs Output Current: 25mA Output Voltage: 5.5V Driver Case Style: TSSOP No. of Pins: 24Pins Input Voltage Min: 2.3V Input Voltage Max: 5.5V Switching Frequency: 1MHz Operating Temperature Min: -40°C Operating Temperature Max: 85°C Packaging: Each Product Range: - Automotive Qualifications Standard: - Dimming Control Type: PWM MSL: MSL 1 - Unlimited Input Voltage: 2.3V to 5.5V LED Driver Application: Backlight, Display, LED Status Information, RGB or RGBA LED Driver SVHC: No SVHC (17-Dec-2015) Topology: - Find similar products grouped by common attribute
