The IC characteristics are closely related to the temperature at which the IC is used, so if the temperature exceeds the maximum junction temperature TjMAX, the device may malfunction or be destroyed. The heat of the IC requires sufficient consideration regarding instantaneous destruction and long-term operation reliability. In order to protect the IC from thermal damage, it is necessary to operate it at temperatures less than the maximum junction temperature TjMAX. Even when the ambient temperature Ta is a normal temperature(25), the chip(junction) temperature 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 : Pc = (Vcc-Vo)xIo+VccxIcca Acceptable loss PdPc Solving for the load current IO in order to operate within the acceptable loss, Io VccInput voltage VoOutput voltage IoLoad current IccaCircuit current Pd - VccxIcca VccVo It is then possible to find the maximum load current IoMAX with respect to the applied voltage Vcc at the time of thermal design.

All rights reserved. 5/9 2009.04 - Rev.A Technical Note BDKA5,BDKA5W Series,BD00KA5W Series Terminal Vicinity Settings and Cautions Vcc Terminal Please attach a capacitor (greater than 1F) between Vcc and GND. The capacitance values differ depending on the application, so chose a capacitor with sufficient margin and verify the operation on actual board. GND Terminal Please be sure to keep the set ground and IC ground at the same potential level so that a potential difference does not arise between them. If a potential difference arises between the set ground and the IC ground, the preset voltage will not be output properly, causing the system to become unstable. Please reduce the impedance by making the ground patterns as wide as possible and reducing the distance between the set ground and the IC ground as much as possible. CTL Terminal 31.25k The CTL terminal is turned ON at 2.0V and higher, and OFF at 0.8V and lower, within the operating power supply voltage CTL range.The power supply and the CTL terminal may be started up and shut down in any order without problems. 25k Fig.23 Input equivalent circuit ESR () Vo Terminal Please be sure to attach an anti-oscillation capacitor between Vo and GND. 100 Oscillation region OUT 10 Stable region IC 1F ESR Cin 1 Vcc Vcc 1F VCTL 2V 0.1 OUT 1F CTL GND ADJ R2 Io(ROUT) R1 R1=30k,R2=2k 0.01 0 100 200 300 400 Iout(mA) Fig.24 Output Equivalent Circuit 500 Io(mA) Fig.25 ESR-Io Characteristics Be sure to place an anti-oscillation capacitor between the output terminal and the GND. Oscillations may arise if the capacitance value changes, due to factors such as temperature changes. A 1F capacitor with small internal series resistance (ESR) such as a ceramic capacitor is recommended as an anti-oscillation capacitor. Ceramic capacitors generally have favorable temperature characteristics and DC bypass characteristics. When selecting a ceramic capacitor, a high voltage capacitor (good DC bypass characteristics) with temperature characteristics that are superior to those of X5R or X7R, is recommended. In applications where input voltage and load fluctuations are rapid, please decide on a capacitor after sufficiently confirming its properties according to its specifications in the actual application.

All rights reserved. 6/9 2009.04 - Rev.A Technical Note BDKA5,BDKA5W Series,BD00KA5W Series Other Caution Protection Circuits Over-current Protection Circuit A built-in over-current protection circuit corresponding to the current capacity prevents 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 restricted and does not latch even when a large current momentarily flows through the system with a high-capacitance capacitor. However, while this protection circuit is effective for the prevention 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 over-current protection circuit has negative current capacity characteristics with regard to temperature. Thermal Shutdown Circuit (Thermal Protection) This system has a built-in temperature protection circuit for the purpose of protecting the IC from thermal damage. As shown in Fig. 20-22, this must be used within the range of acceptable loss, but if the acceptable loss is continuously exceeded, the chip temperature Tj increases, causing the thermal shutdown 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 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 overloaded 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 through 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.27). Reverse current OUT Vcc CTL GND Fig.27 : Bypass diode This IC is BI-CMOS IC that has a P-board (substrate) and P+ isolation between each element, as shown in Fig.28. A P-N junction is formed between this P-layer and the N-layer of each element, and the P-N junction operates as : - a parasitic diode when the electric potential relationship is GND> Terminal A, GND> Terminal B, or - a parasitic transistor when the electric potential relationship is Terminal B > GND> Terminal A. Parasitic elements are structurally inevitable in the IC. The operation of parasitic elements induces mutual interference between circuits, causing malfunctions and eventually the destruction of the IC. Take precaution as 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 input terminal.
