LEDs
A LED (light-emitting diode) is a small, energy-efficient light source that is commonly used in a variety of applications. LED technology has advanced significantly in recent years, making it a popular choice for a wide range of lighting needs. LEDs are known for their low power consumption, long lifespan, and ability to produce a bright, directional light. One of the primary use cases for LEDs is in general lighting, where they are used in everything from residential and commercial lighting to automotive and aviation lighting. LEDs are also commonly used in electronic displays, such as TVs, computer monitors, and smartphones, as well as in signaling and indication applications, such as traffic lights and exit signs. If you are looking for high-quality LED resources, flux.ai has the world's largest community-driven public library of LED footprints, symbols, datasheets, and simulation models. Whether you are a designer, engineer, or manufacturer, you can find the resources you need to work with LEDs in your projects.
TM1814
TM1814 is four channels LED constant current adjustable driver IC with function of internal control synchronizing, which can achieve a wide range of display as MCU inputs one group of data set by constant current and PWM to TM1814. When input signal is disconnected, it can realize synchronized fixation of colorful pattern change and prevent in-operation of subsequent cascade chip caused by chip damage. Internal chip is integrated with MCU solidification program and single wire digital interface, data flip-latch, LED constant current driver, circuit, etc. Internal VDD pin is integrated with 5V regulator with less peripheral devices, which applies to guardrail tube, point source and LED decorative products. This product has excellent performance and reliable quality. Features Adopt power CMOS technology Withstand voltage of OUT output port is 32V 5 V voltage-regulator tube is built into VDD, and the voltage supports 6-24 V after cascading the resistor Constant current can achieve level 64 adjustment (6.5 mA-38mA) PWM brightness controls circuit, and 256 brightness is adjustable Accurate current output value Maximum error (between channels): ±3% Maximum error (between chips): ±5% Single line serial concatenated port Oscillation mode: build in RC vibration and conduct clock synchronization according to signals on data line. After receiving the data from this unit, it can reproduce follow-up data and send it to lower level through data output end, and signals will not be distorted and reduced along with cascade Build in power on reset circuit, and after powering on reset, all registers are initialized to zero External control mode data transmission rate is 800 KHZ Internal control mode data transmission rate is 500 KHZ Internal control mode chip sends 2048 points of data Encapsulation mode: SOP8 #CommonPartsLibrary #IntegratedCircuit
