bd9560muv technical note 19/21 www.rohm.com 2009.04 - rev.b ? 2009 rohm co., ltd. all rights reserved. operation notes and precautions 1. this integrated circuit is a monolithic ic, which (as shown in the figure below), has p isolation in the p substrate and between the various pins. a p-n junction is formed from this p layer and n layer of each pin, with the type of junction depending on the relation between each potential, as follows: ? when gnd element a element b, the p-n junction is a diode. ? when element b gnd element a, the p-n junction oper ates as a parasitic transistor. parasitic diodes inevitably occur in the structure of the ic. th e operation of parasitic diodes can result in mutual interferen ce among circuits, as well as operating malfunctions and physical damage. therefore, be careful to avoid methods by which parasitic diodes operate, such as applying a voltage lower than the gnd (p substrate) voltage to an input pin. 2. in some modes of operation, power supply voltage and pin voltage are reversed, giving rise to possible internal circuit damage. for example, when the external capacitor is charged, the electric charge can cause a vcc short circuit to the gnd. in order to avoid these problems, inserting a vcc series countercurrent prevention diode or bypass diode between the various pins and the vcc is recommended. 3. absolute maximum rating although the quality of this ic is rigorously controlled, the ic may be destroyed when applied voltage or operating temperature exceeds its absolute maximum rating. because short mode or open mode cannot be specified when the ic is destroyed, it is important to take physical safety measures such as fusing if a special mode in excess of absolute rating limits is to be implemented. 4.gnd potential make sure the potential for the gnd pin is always kept lo wer than the potentials of all other pins, regardless of the operating mode. 5. thermal design in order to build sufficient margin into the thermal desi gn, give proper consideration to the allowable loss (power dissipation) in actual operation. 6. short-circuits between pins and incorrect mounting position when mounting the ic onto the circuit board, be extremely ca reful about the orientation and position of the ic. the ic may be destroyed if it is incorrectly positioned for mounting. do not short-circuit between any output pin and supply pin or ground, or between the output pins themselves. accidental attachment of small ob jects on these pins will cause shorts and may damage the ic. gnd (pin a) p+ p+ n n n p p parasitic pin gnd resistance gnd parasitic pin p substrate n p n c (pin b) b e p+ p+ n n transistor (npn) (pin b) c e b gnd parasitic tit other pins in close (pin a) parasitic gnd vcc pin countercurrent bypass diode
