technical note 8/9 www.rohm.com 2011.02 - rev. a ? 2011 rohm co., ltd. all rights reserved. BD2200GUL, bd2201gul 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 br eaking 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 gnd line design pcb pattern to provide low impedance for the wiri ng between the power supply and the gnd lines. pay attention to the interference by common impedance of layout pattern when there are plural power supplies and gnd lines. especially, when there are gnd pattern for small si gnal and gnd pattern for large current included the external circuits, separate each gnd pattern. furthermore, for all power suppl y terminals to ics, mount a capacitor between the power supply and the gnd terminal. at the same ti me, in order to use a capacitor, thoroughly check to be sure the characteristics of the capacitor to be used presen t no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant. (3) gnd voltage make setting of the potential of the gnd terminal so that it will be maintained at the minimum in any operating state. furthermore, check to be sure no terminals are at a potentia l lower than the gnd voltage including an actual electric transient. (4) short circuit between terminals 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 terminals or between the terminal and the power supply or the gnd terminal, the ics can break down. (5) operation in strong electromagnetic field be noted that using ics in the strong elec tromagnetic field can malfunction them. (6) input terminals in terms of the construction of ic, parasitic elements are in evitably formed in relation to potential. the operation of the parasitic element can cause interference with circuit operati on, thus resulting in a malf unction and then breakdown of the input terminal. therefore, pay thorou gh attention not to handle the input te rminals, such as to apply to the input terminals a voltage lower than the gnd respectively, so that any parasitic element wi ll operate. furthermore, do not apply a voltage to the input terminals when no power supply voltage is applied to the ic. in addition, even if the power supply voltage is applied, apply to the input terminals 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 c onstant with consideration given to a degradation in the nominal capacitance due to dc bias and c hanges in the capacitance due to temperature, etc. (8) thermal design perform thermal design in which there are adequate margins by taking into account the power dissipation (pd) in actual states of use.
