TEL: +886-3-579-0068, FAX: +886-3-579-7534, E-mail: [email protected] - 1 - May 2014, V1.01 MBI6034 PWM-Embedded 3x4-Channel Constant-Current Sink Driver with Error Detection for LED Strips Product Description MBI6034 is a 3x4-channel, constant-current, PWM-embedded sink driver for LED strips. MBI6034 provides constant current ranging from 3mA to 45mA for each output channel and are adjustable through only single external resistor and corresponding current gain settings. Besides, MBI6034 supports 6~24V wide range power systems and sustains 28V at output channels. With Scrambled-PWM (S-PWM) technology, MBI6034 enhances pulse width modulation by scrambling the “on” time into several “on” periods to increase visual refresh rate at the same gray scale performance. Besides, the gray scale clock (GCLK) is generated by the embedded oscillator. Moreover, MBI6034 provides 16-bit gray scale which provides 65,536 gray scales for each LED to enrich the color. 3 independent 7-bit current gain settings are built-in MBI6034, so the user can set independent output current for R/G/B LED by a single current set resistor and current gain instead of 3 current set resistors. MBI6034 can detect faults of LED open, short or the wire disconnection including SDI and CLK, and an innovative bi-directional transmission realizes a cost saving fault report read back without additional wires from the driver IC to the controller. In addition, MBI6034 features a two-wire transmission interface to make cluster-to-cluster connection easier. To improve the transmission quality, MBI6034 provides phase-inversed output clock to eliminate the accumulation of signal pulse width distortion. MBI6034 adopts manual-synchronization to maintain the synchronization of image frames between ICs. - 2 - May 2014, V1.01 MBI6034 Pin Co.
