24 bit led driver

 · NXP Semiconductors PCA Channel Constant Current LED Driver is optimized for dimming and blinking full-color RGBA (Red/Green/Blue/Amber) LEDs, making it ideal for use for status and fun light displays. The PCA features SPI-compatible 4-wire serial bus control and can drive 24 LED outputs, each individually controlled. The LED driver consists of 24 super bright smart LEDs arranged in a circle with an outer diameter of " (66mm), each of which can be addressed because the driver chip is located inside the LED. The LED driver requires manual adjustment of the component, which is only available for the AVR core, but others may have already ported the chip driver code. Accepts V and 5 V micro driver Output current: mA 25 MHz clock frequency High thermal efficiency package Description The STP24DP05 is a monolithic, low-voltage, low current power bit shift register designed for LED panel displays. The device contains an 8 x 3-bit serial-IN, parallel-OUT shift register that.

The PCA is an I²C-bus controlled bit LED driver optimized for voltage switch dimming and blinking mA Red/Green/Blue/Amber (RGBA) LEDs. Each LED output has its own 8-bit resolution ( steps) fixed frequency individual PWM controller that operates at 97 kHz with a duty cycle that is adjustable from 0 % to % to allow the LED to be set to a specific brightness value. LED Driver - LED Driver ICs High-brightness LED drivers are integrated circuits that are optimized to efficiently drive strings of high-brightness LEDs. Maxim's continually expanding portfolio includes products covering the full range of efficient switch-mode topologies (step-down, step-up, SEPIC) as well as some linear LED drivers. The TLC is a channel, constant-current sink LED driver. Each channel is individually adjustable with pulse-width modulated (PWM) steps. PWM control is repeated automatically with the programmed grayscale (GS) data. GS data are written via a serial interface port. The current value of all 24 channels is set by a single external resistor.

This chip can control 24 separate channels of bit PWM output. Designed (and ideal) for LED control, this board is not good for driving servos. If you need to.
