(2) although we are confident in recommending the sample applic ation circuits, carefully check their characteristics further when using them. when modifying externally attached component constants before use, dete rmine them so that they have sufficient margins by taking into account variations in externally attached components and the rohm lsi, not only for static characteristics but also in cluding transient characteristics. (3) absolute maximum ratings operating or testing the device over the maximu m specifications may damage the part itself as we ll as peripheral components. therefore, please ensure that the specifications are not exceeded. (4) gnd potential ensure that the gnd terminal is at the lowe st potential under all operating conditions. (5) thermal design use a thermal design that allows for a sufficient margin regarding power dissipation (pd) under actual operating conditions.] (6) terminal shorts and mis-mounting incorrect orientation or misalignment of the ic when mounting to the pcb may damage part. short-circuits caused by the introduction of foreign matter between the output terminals or across the output and power supply or gnd may also result in destruction. (7) operation in a strong magnetic field operation in a strong electromagnet ic field may cause malfunction. (8) power source voltage set the power source voltage so that vcc R vdd. (9) reset function the power on reset circuit, which initializes internal settings, may malfunction during abrupt power ons. therefore, set the time constant so as to sati sfy the power source rise time. thermal derating curve ssop-b20(bh2221fv) ssop-b16(BH2223FV) fig.18 0 100 200 300 400 500 600 700 0 25 50 75 100 125 ta [] pd [mw] mounted on a 70x70x1.6mm fr4 glass epoxy board (copper foil area 3% or below)
