(Auto Return 0). (2) Hardware reset ・It shifts to hardware reset by changing RESETB 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 changing RESETB pin “L” → “H”. ・RESETB 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”) ●VIODET The decline of the VIO voltage is detected, and faulty operation inside the LSI is prevented by giving resetting to Levelsift block Image Block Diagram VIO VBAT DEToutput Inside reset 2.6V VBAT Reset by VIODET (typ)1.0V VIO VIODET RESETB R Digital pin I/O LEVEL SHIFT RESETB DET output Inside reset Fig.15 Fig.16 When the VIO voltage becomes more than typ1.0V(Vth of NMOS in the IC), VIODET is removed.

(DCDCFON=0) When the start of theDC/DC circuit is done, it has the soft start function to prevent a rush current. Technical Note Force of VBAT and VIO is to go as follows. VBAT VIO TVIOON=min 0.1ms RESETB TRSTB=min 0.1ms TRST=min 0ms EN (*) TSOFT VOUT TVIOOFF=min 0.1ms LEDcurrent (*) An EN signal means the following in the upper figure. EN = “MLEDEN” or “W＊EN” (= LED The LED lighting control of a setup of connection VOUT) But, as for Ta > TTSD (typ : 195° C), a protection function functions, and an EN signal doesn't become effective. TSOFT changes by the capacitor connected to VOUT and inside OSC. TSOFT is Typ 200μs (when the output capacitor of VOUT =1.0μF). Fig.17 Over Voltage protection / Over Current protection DC/DC circuit output (VOUT) is equipped with the over-voltage protection and the over current protection function. A VOUT over-voltage detection voltage is about 5.6V(typ). (VOUT at the time of rise in a voltage) A detection voltage has a hysteresis, and a detection release voltage is about 5.4V (typ). And, when VOUT output short to ground, input current of the battery terminal is limited by an over current protection function. www.rohm.com © 2010 ROHM Co., Ltd.

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 Shut Down Circuit (TSD) This LSI builds in a thermal shutdown 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 rush current For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal powering sequence and delays. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of wiring. (13) About the function description or application note or more. The function description 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. www.rohm.com © 2010 ROHM Co., Ltd.
