●I2C BUS format The writing/reading operation is based on the I2C slave standard. ・Slave address A7 1 A6 1 A5 1 A4 0 A3 1 A2 1 A1 0 W 0
Technical Note
・Bit Transfer SCL transfers 1-bit data during H. SCL cannot change signal of SDA during H at the time of bit transfer. If SDA changes while SCL is H, START conditions or STOP conditions will occur and it will be interpreted as a control signal.
SDA
SCL Data line stable; Data valid Change of data allowed
・START and STOP condition When SDA and SCL are H, data is not transferred on the I2C- bus. This condition indicates, if SDA changes from H to L while SCL has been H, it will become START (S) conditions, and an access start, if SDA changes from L to H while SCL has been H, it will become STOP (P) conditions and an access end.
SDA
SCL
S START Condition
P STOP Condition
・Acknowledge It transfers data 8 bits each after the occurrence of START condition. A transmitter opens SDA after transfer 8bits data, and a receiver returns the acknowledge signal by setting SDA to L.
DATA OUTPUT BY TRANSMITTER not acknowledge DATA OUTPUT BY RECEIVER acknowledge SCL from master 1 2 8 clock pulse for acknowledgement 9

Technical Note
・ Writing protocol A register address is transferred by the next 1 byte that transferred the slave address and the write-in command. The 3rd byte writes data in the internal register written in by the 2nd byte, and after 4th byte or, the increment of register address is carried out automatically. However, when a register address turns into the last address (1Ah), it is set to 00h by the next transmission. After the transmission end, the increment of the address is carried out.

●RGB LED operating 1. Operating mode RGB LED can set up the following operating mode by the setup of the register. ＜Setup register＞ I1**LED : (register) Initial electric current value [mA] IDLT**LED : (register) The electric current Δ value of around 1Step [mA] RGB*SLNUM : (register) slope step number (1,2,4,8,16,32,64 Step) RGB*SL1STEP : (register) The first half slope 1Step time [ms] RGB*SL2STEP : (register) The latter half slope 1Step time [ms] RGB*WT1TM : (register) The first half lighting time [ms] RGB*WT2TM : (register) The latter half lighting time [ms]
Technical Note
As for the following setup, calculate it from the above setup. I2**LED : At the time of middle lighting current value [mA] = I1**LED + IDLT**LED x RGB*SLNUM (In case of the value that a calculation exceeds maximum value, the current value is at the limit with maximum.) RGB*SL1TM : The first half slope time [ms] = RGB*SL1STEP x RGB*SLNUM RGB*SL2TM : The latter half slope time [ms] = RGB*SL2STEP x RGB*SLNUM Each setup is necessary for DC current (at Normal mode or Blink mode).
(* : 1/ 2 channels is shown. ** : R1/G1/B1/R2 /G2/B2 is shown.) Note) The current value in the table, it is value when 120kΩ is connected to ISET pin.

(C)Section : It transits at the step time of a half times when it was set up with RGB*SL1STEP. The time of the total (RGB*SL1TM) is calculated with RGB*SL1STEP x RGB*SLNUM. A similar movement is done on the descent (RGB*SL2TM) side as well. The acceptance of the setup of a register concerned with LED working during the slope movement stops. But, a RGB*STA signal interrupts even during the slope movement, and it is possible that LED is turned off.

Technical Note
1. Reset There are two kinds of reset, software reset and hardware reset. (1) Software reset ・All the registers are initialized more than making a register (SFTRST) setup "1". ・The register of software resetting is an automatic return (Auto Return 0). (2) Hardware reset ・It shifts to hardware reset by changing RESET pin “H” → “L”. ・The condition of all the registers under hardware reset pin is returned to the initial value, and it stops accepting all address. ・It’s possible to release from a state of hardware reset by setting register “L” → “H”. ・RESET pin has delay circuit. It doesn’t recognize as hardware reset in “L” period under 5μs. (3) Reset Sequence ・When hardware reset was done during software reset, software reset is canceled when hardware reset is canceled. (Because the initial value of software reset is “0”) 2. Thermal shutdown The blocks which thermal shutdown function is effective in the following. Charge pump LED Driver REG1 REG2 is not shut down by thermal shutdown function, because REG2 can be used for I/O voltage. A thermal shutdown function works in about 195 ℃. Detection temperature has a hysteresis, and detection release temperature is about 175 ℃. (Design reference value)

Technical Note
●Notes for use (1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc.
(2) Power supply and ground line Design PCB pattern to provide low impedance for the wiring between the power supply and the ground lines. Pay attention to the interference by common impedance of layout pattern when there are plural power supplies and ground lines. Especially, when there are ground pattern for small signal and ground pattern for large current included the external circuits, please separate each ground pattern. Furthermore, for all power supply pins to ICs, mount a capacitor between the power supply and the ground pin. At the same time, in order to use a capacitor, thoroughly check to be sure the characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant. (3) Ground voltage Make setting of the potential of the ground pin so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no pins are at a potential lower than the ground voltage including an actual electric transient. (4) Short circuit between pins and erroneous mounting In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between pins or between the pin and the power supply or the ground pin, the ICs can break down. (5) Operation in strong electromagnetic field Be noted that using ICs in the strong electromagnetic field can malfunction them. (6) Input pins In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input pin. Therefore, pay thorough attention not to handle the input pins, such as to apply to the input pins a voltage lower than the ground respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input pins when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input pins a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics. (7) External capacitor In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc. (8) Thermal shutdown circuit (TSD) This LSI builds in a thermal shutdown (TSD) circuit. When junction temperatures become detection temperature or higher, the thermal shutdown circuit operates and turns a switch OFF. The thermal shutdown circuit, which is aimed at isolating the LSI from thermal runaway as much as possible, is not aimed at the protection or guarantee of the LSI. Therefore, do not continuously use the LSI with this circuit operating or use the LSI assuming its operation. (9) Thermal design Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (Pd) in actual states of use. (10) LDO Use each output of LDO by the independence. Don’t use under the condition that each output is short-circuited because it has the possibility that an operation becomes unstable. (11) About the pin for the test, the un-use pin Prevent a problem from being in the pin for the test and the un-use pin under the state of actual use. Please refer to a function manual and an application notebook. And, as for the pin that doesn't specially have an explanation, ask our company person in charge. (12) About the function description or application note or more. The function manual and the application notebook are the design materials to design a set. So, the contents of the materials aren't always guaranteed. Please design application by having fully examination and evaluation include the external elements.
