BU1570KN, bu1571kn technical note 7/8 www.rohm.com 2009.04- rev.b ? 2009 rohm co., ltd. all rights reserved. cautions on use (1)absolute maximum ratings an excess in the absolute maximum ratings, such as supply volt age, 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, consider ation should be given to take physical safety measures including the use of fuses, etc. (2)operating conditions these conditions represent a range within which characterist ics can be provided approximately as expected. the electrical characteristics are guaranteed under t he conditions of each parameter. (3)reverse connection of power supply connector the reverse connection of power supply connector can break down ics. take protective measures against the breakdown due to the reverse connection, such as mounting an external diode between the power supply and the ic?s power supply terminal. (4)power supply line design pcb pattern to provide low impedance for the wiring between the power supply and the gnd lines. in this regard, for the digital block power supply and the ana log block power supply, even though these power supplies has the same level of potential, separate the powe r supply pattern for the digital block from that for the analog block, thus suppressi ng the diffraction of digital noises to the analog block power s upply resulting from impedance common to the wiring patterns. for the gnd line, give consideration to des ign the patterns in a similar manner. furthermore, for all power supply terminals to ics, mount a capacitor between the power supply and the gnd terminal. at the same time, in order to use an electrolytic capacitor, thoroughly check to be sure the characteristics of the capacitor to be us ed present no problem including the occurrence of capacity dr opout at a low temperature, t hus determining the constant. (5)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 potential lo wer than the gnd voltage including an actual electric transient . (6)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 te rminal, the ics can break down. (7)operation in strong electromagnetic field be noted that using ics in the strong elec tromagnetic field can malfunction them. (8)inspection with set pcb on the inspection with the set pcb, if a capacitor is conne cted to a low-impedance ic terminal, the ic can suffer stress. therefore, be sure to discharge from the set pcb by each proc ess. furthermore, in order to mount or dismount the set pcb to/from the jig for the inspection process, be sure to turn o ff the power supply and then mount the set pcb to the jig. after t he completion of the inspection, be sure to turn off the power supply and then dismount it from the jig. in addition, for protecti on against static electricity, establish a ground for the assembly process and pay thorough attention to the transportation and th e storage of the set pcb. (9)input terminals in terms of the construction of ic, parasi tic elements are inevitably formed in relati on to potential. the operation of the par asitic element can cause interference with circuit operation, thus resu lting in a malfunction and then breakdown of the input terminal . therefore, pay thorough attention not to handl e the input terminals, such as to apply to the input terminals a voltage lower th an the gnd respectively, so that any parasitic element will operat e. 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 with in the guaranteed value of el ectrical characteristics. (10)ground wiring pattern if small-signal gnd and large-current gnd are provided, it wi ll be recommended to separate the large-current gnd pattern from the small-signal gnd pattern and establish a single ground at the reference point of the set pcb so that resistance to the wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltag es of the small-signal gnd. pay attention not to cause fluctuations in the g nd wiring pattern of external parts as well. (11)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.
