16-bit Fm+ I2C-bus 100 mA 40 V LED driver; ? 16 LED drivers. Each output programmable at: ? Off\n? On\n? Programmable LED brightness\n? Programmable group dimming/blinking mixed with individual LED brightness\n? 1 MHz Fast-mode Plus compatible I2C-bus interface with 30 mA high drive capability on SDA output for driving high capacitive buses\n? 256-step (8-bit) linear programmable brightness per LED output varying from fully off (default) to maximum brightness using a 97 kHz PWM signal\n? 256-step group brightness control allows general dimming (using a 190 Hz PWM signal) from fully off to maximum brightness (default)\n? 256-step group blinking with frequency programmable from 24 Hz to 10.73s and duty cycle from 0 % to 99.6 %\n? Sixteen open-drain outputs can sink between 0 mA to 100 mA and are tolerant to a maximum off-state voltage of 40 V. No input function\n? Output state change programmable on the Acknowledge or the STOP Command to update outputs byte-by-byte or all at the same time (default to 'Change on STOP')\n? Active LOW Output Enable (OE) input pin allows for hardware blinking and dimming of the LEDs\n? 7 hardware address pins allow 126 PCA9622 devices to be connected to the same I2C-bus and to be individually programmed\n? 4 software programmable I2C-bus addresses (one LED Group Call address and three LED Sub Call addresses) allow groups of devices to be addressed at the same time in any combination (for example, one register used for 'All Call' so that all the PCA9622s on the I2C-bus can be addressed at the same time and the second register used for three different addresses so that 1/3 of all devices on the bus can be addressed at the same time in a group). Software enables and disables for I2C-bus address\n? Software Reset feature (SWRST Call) allows the device to be reset through the I2C-bus\n? 25 MHz internal oscillator requires no external components\n? Internal power-on reset\n? Noise filter on SDA/SCL inputs\n? No glitch on power-up\n? Supports hot insertion\n? Low standby current\n? Operating power supply voltage (VDD) range of 2.3 V to 5.5 V\n? 5.5 V tolerant inputs on non-LED pins\n? -40 °C to +85 °C operation\n? ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM perJESD22-C101\n? Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA\n? Package offered: TSSOP32\n; The PCA9622 is an I2C-bus controlled 16-bit LED driver optimized for voltage switchdimming and blinking 100 mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED outputhas its own 8-bit resolution (256 steps) fixed frequency individual PWM controller thatoperates at 97 kHz with a duty cycle that is adjustable from 0 % to 99.6 % to allow theLED to be set to a specific brightness value. An additional 8-bit resolution (256 steps)group PWM controller has both a fixed frequency of 190 Hz and an adjustable frequencybetween 24 Hz to once every 10.73 seconds with a duty cycle that is adjustable from 0 %to 99.6 % that is used to either dim or blink all LEDs with the same value.\nEach LED output can be off, on (no PWM control), set at its individual PWM controllervalue or at both individual and group PWM controller values. The PCA9622 operates witha supply voltage range of 2.3 V to 5.5 V and the 100 mA open-drain outputs allowvoltages up to 40 V.\nThe PCA9622 is one of the first LED controller devices in a new Fast-mode Plus (Fm+)family. Fm+ devices offer higher frequency (up to 1 MHz) and more densely populatedbus operation (up to 4000 pF).\nThe active LOW Output Enable input pin (OE) blinks all the LED outputs and can be usedto externally PWM the outputs, which is useful when multiple devices need to be dimmedor blinked together without using software control.\nSoftware programmable LED Group and three Sub Call I2C-bus addresses allow all ordefined groups of PCA9622 devices to respond to a common I2C-bus address, allowing,for example, all red LEDs to be turned on or off at the same time or marquee chasingeffect, thus minimizing I2C-bus commands. Seven hardware address pins allow up to126 devices on the same bus.\nThe Software Reset (SWRST) Call allows the master to perform a reset of the PCA9622through the I2C-bus, identical to the Power-On Reset (POR) that initializes the registers totheir default state causing the outputs to be set HIGH (LED off). This allows an easy andquick way to reconfigure all device registers to the same condition.\nThe PCA9622, PCA9625 and PCA9635 software are identical and if the PCA9622 on-chip100 mA NAND FETs do not provide enough current or voltage to drive the LEDs, then thePCA9635 with larger current or higher voltage external drivers can be used.\n | 恩XP | 恩XP | ||
