  • Thermal Design Fig.26 Fig.27(Reference data) When using at temperatures over Ta=25℃, please refer to the heat reducing characteristics shown in Fig.26 and Fig.27. The IC characteristics are closely related to the temperature at which the IC is used, so it is necessary to operate the IC at temperatures less than the maximum junction temperature Tjmax. Fig.26 and Fig.27 shows the acceptable loss and heat reduci ng characteristics of the TO252-5 package. Even when the ambient temperature Ta is a normal temperature (25 ℃), the chip (junction) temperatur e Tj may be quite high so please operate the IC at temperatures less than the acceptable loss Pd. The calculation method for power consumption Pc(W) is as follows :(Fig.27③) Pc=(Vcc-Vo)×Io+Vcc×Ib Acceptable loss Pd≧Pc Solving this for load current Io in order to operate within the acceptable loss, It is then possible to find the maximum load current Io Max with respect to the applied voltage Vcc at the time of thermal design. Calculation Example) When Ta=85℃ BD33C0AWFP:Vcc=8.3V,Vo=3.3V BD50C0AWFP:Vcc=10V,Vo=5.0V Please refer to the above information and keep thermal desig ns within the scope of acceptable loss for all operating temperature ranges.

  • Notes for use 1. Absolute maximum ratings Use of the IC in excess of absolute maximum ratings (suc h as the input voltage or operating temperature range) may result in damage to the IC. Assumptions should not be made regarding the state of the IC (e.g., short mode or open mode) when such damage is suffered. If operational values are expected to exceed the maximum ratings for the device, consider adding protective circuitry (such as fuses) to eliminate the risk of damaging the IC. 2. Electrical characteristics described in these specifications may vary, depending on temperature, supply voltage, external circuits and other conditions. Therefore, be sure to check all relevant factors, including transient characteristics. 3. GND potential The potential of the GND pin must be the minimum potential in the system in all operating conditions. Ensure that no pins are at a voltage below the GND at any time, regardless of transient characteristics. 4. Ground wiring pattern When using both small-signal and large- current GND traces, the two ground trac es should be routed separately but connected to a single ground potential within the applicati on in order to avoid variations in the small-signal ground caused by large currents. Also ensur e that the GND traces of external components do not cause variations on GND voltage. The power supply and ground lines must be as short and thick as possible to reduce line impedance. 5. Inter-pin shorts and mounting errors Use caution when orienting and positioning the IC for mounting on printed circuit boards. Improper mounting may result in damage to the IC. Shorts between output pins or between output pins and the power supply or GND pins (caused by poor soldering or foreign objects) may result in damage to the IC. 6. Operation in strong electromagnetic fields Using this product in strong electromagnetic fields ma y cause IC malfunction. Caution should be exercised in applications where strong electromagnetic fields may be present. 7. Testing on application boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance pin may subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should always be turned off completely before connecting or removing it from a jig or fixture during the evaluation process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 8. Thermal consideration Use a thermal design that allows for a sufficient margin in light of the Pd in actual operating conditions. Consider Pc that does not exceed Pd in actual operating conditions. (Pd≧Pc) Tjmax : Maximum junction temperature=150℃, Ta : Peripheral temperature[℃] , θja : Thermal resistance of package-ambience[℃/W], Pd : Package Power dissipation [W], Pc : Power dissipation [W], Vcc : Input Voltage, Vo : Output Voltage, Io : Load, Ib : Bias Current Package Power dissipation : Pd (W)=(Tjmax -Ta)/θja Power dissipation : Pc (W)=(Vcc -Vo)×Io+Vcc×Ib 9. Vcc pin Insert a capacitor(Vo≧5V:capacitor≧1µF ~ , Vo<5V:capacitor≧2.2µF ~)between the Vcc and GND pins. The appropriate capacitance value varies by application. Be sure to allow a sufficient margin for input voltage levels. Electric capacitance Ceramic capacitors,Low ESR capacitors IC

www.rohm.com 2011.07 - Rev. A © 2011 ROHM Co., Ltd. All rights reserved. BD33C0AWFP, BD50C0AWFP 10. Output pin It is necessary to place capacitors between each output pi n and GND to prevent oscillat ion on the output. Usable capacitance values range from 1µF to 1000µF. Ceramic capacitors can be used as long as their ESR value is low enough to prevent oscillation (0.001Ω to 20Ω). Abrupt fluctuations in input vo ltage and load conditions may affect the output voltage. Output capacitance values should be det ermined only through sufficient testing of the actual application. 11. CTL pin Do not make voltage level of chip enable pin keep floating level, or in between VthH and VthL. Otherwise, the output voltage would be unstable or indefinite. 12. For a steep change of the Vcc voltage Because MOS FET for output Transistor is used when an input voltage change is very steep, it may evoke large current. When selecting the value of external circ uit constants, please make sure that the operation on the actual application takes these conditions into account. 13. For an infinitesimal fluct uations of output voltage. At the use of the application that infinitesimal fluctuations of output voltage caused by so me factors (e.g. disturbance noise, input voltage fluctuations, load fluc tuations, etc.), please take enough meas ures to avoid some influence (e.g. insert the filter, etc.). 14. Over current protection circuit (OCP) The IC incorporates an integrated over-cu rrent protection circuit that operates in accordance with the rated output capacity. This circuit serves to protect the IC from damag e when the load becomes shorted. It is also designed to limit output current (without latching) in the event of a large and instantaneous current flow from a large capacitor or other component. These protection circuits are effective in preventing damage due to sudden and unexpected accidents. However, the IC should not be used in applications characterized by the continuous or transitive operation of the protection circuits. 15. Thermal shutdown circuit (TSD) The IC incorporates a built-in thermal shutdown circuit, which is designed to turn the IC off completely in the event of thermal overload. It is not designed to pr otect the IC from damage or guarantee it s operation. ICs should not be used after this function has activated, or in applications where the operation of this circuit is assumed.

Applications or inspection processes where the potential of the Vcc pin or other pins may be reversed from their normal state may cause damage to the IC's internal circuitry or elements. Use an output pin capacitance of 1000µF or lower in case Vcc is shorted with the GND pin while the external capacitor is charged. Insert a diode in series with Vcc to prevent reverse current flow, or insert bypass diodes between Vcc and each pin. 17. Positive voltage surges on VCC pin A power zener diode should be inserted between VCC and GND for protection against voltage surges of more than 35V on the VCC pin. 18. Negative voltage surges on VCC pin A schottky barrier diode should be inserted between VCC and GND for protection against voltages lower than GND on the VCC pin. 19. Output protection diode Loads with large inductance components may cause reverse current flow during startup or shutdown. In such cases, a protection diode should be inserted on the output to protect the IC. 20. Regarding input pins of the IC This monolithic IC contains P+ isolation and P substrat e layers between adjacent elements in order to keep them isolated. PN junctions are formed at the intersection of th ese P layers with the N layers of other elements, creating parasitic diodes and/or transistors. For example (refer to the figure below): ○When GND > Pin A and GND > Pin B, the PN junction operates as a parasitic diode ○When GND > Pin B, the PN junction operates as a parasitic transistor Parasitic diodes occur inevitably in the structure of the IC , and the operation of these parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (a nd thus to the P substrate) should be avoided.
