Interface ICs
An interface IC is a type of integrated circuit that is designed to facilitate communication between two devices or systems. These devices are commonly used in electronic systems to enable the transfer of data and control signals between different components or subsystems. Some common use cases for interface ICs include connecting microcontrollers to peripherals such as sensors or displays, linking multiple processors together in a network, and enabling communication between devices using different communication protocols. Flux.ai has the world's largest community-driven public library of interface ICs, with footprints, symbols, datasheets, and simulation models. This library is a valuable resource for engineers and designers who need access to accurate and up-to-date information on these important components. Whether you are working on a new design project or simply looking to learn more about interface ICs, Flux.ai is an excellent resource to help you find the information you need.
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
