Translated from: TM1829_V1.4-chin.pdf - by BNT - Date: 07.12.13 Page 01 ------------------------------------------------------Three-channel constant current LED driver TM1829 Characterization TM1829 is a three-channel LED (light emitting diode) constant current drive control of a dedicated circuit, the internal MCU integrated single-wire digital interface, data latches Devices, LED constant current driver circuit, PWM brightness control circuit. Through the single-wire digital interface chip (DI, DO) cascade, the external controller only Single line can control the chip and its subsequent cascade chips. Constant luminance value and the PWM output port can be individually TM1829 by peripheral controller Setting. VDD pin internal 5V regulator integrated, less peripheral devices.
