Features:
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.
1, Adopt power CMOS technology
2, Withstand voltage of OUT output port is 32V
3, 5 V voltage-regulator tube is built into VDD, and the voltage supports 6-24 V after cascading the resistor
4, Constant current can achieve level 64 adjustment (6.5 mA-38mA)
5, PWM brightness controls circuit, and 256 brightness is adjustable
6, Accurate current output value
Maximum error (between channels): ±3%
Maximum error (between chips): ±5%
7, Single line serial concatenated port
8, 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
9, Build in power on reset circuit, and after powering on reset, all registers are initialized to zero
10, External control mode data transmission rate is 800 KHZ
11, Internal control mode data transmission rate is 500 KHZ
12, Internal control mode chip sends 2048 points of data
13, Encapsulation mode: SOP8
