... BD9701FP/CP-V5/T/T-V5,BD9703FP/CP-V5/T/T-V5,BD9702CP-V5/T/T- pin input This monolithic IC which (as below) has P+ substrate and betweenthe various pin. A P-N junction is formed from this P layer of each pin. For example the relation between each potential is as follows. (When GND > PinB and GND > PinA, the P-N junction operates as a parasitic diode.) Parasitic diodes can occur inevitably in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits as well as operation faults and physical damage ...
