MCU-PCA9685 16 canaux Servo Driver 12 bits fm+I2C Bus PWM Controller Servo Control Module - Générique

MCU-PCA9685 16 canaux Servo Driver 12 bits fm+I2C Bus PWM Controller Servo Control Module 1. MHz Fast Mode Plus compatible I2C bus interface with 30mA high drive capability on SDA to drive high capacitive buses;Each LED output can achieve 4096 levels (12 bits) of linear programmable brightness from completely off (default) to brightness. 2. 16 push-pull outputs (sinking 25mA sink current and providing 10mA source current at 5V) that can be software-programmed as open-drain LED output selection (default is push-pull), with no input function. 3. The output state can be programmed to change on response or stop to update all outputs simultaneously or update the output -by- (default is ""stop change"").Low-active output enable input pin, when this pin is high, the LED output can be programmed to 0, 1 or high impedance (default is high impedance at power-on). 4. 6 hardware address pins allow 62 PCA9685 devices to be connected on the same I2C bus LED output frequency (all LEDs) is usually 40Hz to 1000Hz (when the oscillator is 25MHz, the default value of the prescaler register is 1EH, which will produce a refresh rate of 200Hz). 4 software-programmable I2C bus addresses (one LED group call address and three LED sub-call addresses) allow device groups to be addressed at the same time in any combination (for example, if a register is used for ""All Calls"", all PCA9634 devices on the I2C bus can be addressed at the same time, and the second register is used for three different addresses, then 1/3 of the devices on the bus in a device group can be addressed at the same time), and the I2C bus address can be enabled and disabled by software. Operating voltage range:2.3V to 5.5V Withstands5.5V input Operates in -40 to 85 environments ESD protection exceeds 2000V HBM/JESD22-A114, 200V MM/JESD22-A115 and 1000V CDM/JESD22-C101 JEDEC standard JESD78 enters lockup test when exceeding 100mA Due todifferent batches, there may be differences in product appearance and printed text, which will not affect use.
