7/8 other points of caution 1)protection circuits over-current protection circuit a built-in over-current protection circuit co rresponding to the current capacity prev ents the destruction of the ic when there are load shorts. this protection circuit is a ?7?-shaped current control circuit that is designed such that the current is rest ricted and does not latch even when a large current momentarily flow s through the system with a high-capacitance capacitor. however, while this protection circuit is effective for the pr evention of destruction due to unexpected accidents, it is not suitable for continuous operation or transient use. please be aware when creating thermal designs that the overcurrent protection circuit has negative current capacity characterist ics with regard to temperature (refer to figs.4 and 16). thermal shutdown circuit (thermal protection) this system has a built-in temperature prot ection circuit for the purpose of protecti ng the ic from thermal damage. as shown above, this must be used within the range of acceptable loss, but if the acceptable loss happens to be continuously exceeded, the chip temperature tj increases, causing th e temperature protection circuit to operate. when the thermal shutdown circuit operates, the operation of the circuit is suspended. the circuit resumes operation immediately after the chip temperature tj decreases, so the output repeats the on and off states (please refer to figs.12 and 24 for the temperatures at which the temperature protection circuit operates). there are cases in which the ic is destroyed due to thermal runaway when it is left in the overlo aded state. be sure to avoid leaving the ic in the overloaded state. reverse current in order to prevent the destruction of the ic when a reverse current flows th rough the ic, it is recommended that a diode be placed between the vcc and vo and a pathway be created so that the current can escape (refer to fig.35). 2) this ic is bipolar ic that has a p-board (substrate) and p+ isolation layer between each devise, as shown in fig.36. a p-n junction is formed between this p-layer and the n-layer of each device, and the p-n junction operates as a parasitic diode when the electric potent ial relationship is gnd> terminal a, gnd> terminal b, while it operates as a parasitic transistor when the electric potential relationship is terminal b gnd> terminal a. parasitic devices are structurally inevitable in the ic. the operation of parasitic devices induces mutual interference between circuits, causing malfunctions and eventually the destruction of the ic. it is necessary to be careful not to use the ic in ways that would cause parasitic elements to operate. for example, applying a voltage that is lower than the gnd (p-board) to the i nput terminal. fig. 37: example of the basic structure of a bipolar ic part number selection gnd n p n p+ p+ parasitic element or transistor (pin b) b e transistor ( npn ) n p n gnd o (pin a) gnd n p+ resistor parasitic element p n p p+ n (pin a) parasitic element or transistor (pin b) g nd c b e parasitic element g nd fig. 36:bypass diode out vcc ctl gnd reverse current rohm model name output voltage current capacity cc0 : 1a dd0 : 2a shutdown switch w : with switch none : without switch t : f p : hfp : b d d w h 0 a p e 2 f package specification tr : embossed taping(hrp5) e2 : embossed taping(to252-3,5) none : tube container v5 :foaming(v5 only) package to220-3,5 to252-3,5 hrp5 unit:mm to252-3 unit:mm to252-5 unit:mm hrp5
