The characteristics of the IC are greatly influenced by the operating temperature. If the temperature is in excess of the maximum junction temperature Tjmax, the elements of the IC may be deteriorated or damaged. It is necessary to give sufficient consideration to the heat of the IC in view of two points, i.e., the protection of the IC from instantaneous damage and the maintenance of the reliability of the IC in long-time operation. In order to protect the IC from thermal destruction, it is necessary to operate the IC not in excess of the maximum junction temperature Tjmax. Fig. 23 illustrates the power dissipation/heat mitigation characteristics for the TO252 package. Operate the IC within the power dissipation Pd. The following method is used to calculate the power consumption PC (W). Vcc : Input voltage Vo : Output voltage Io : Load current Icc : Total supply current PC=(VCC-VO)xIO+VCCxICC Power dissipation PdPC The load current IO is obtained to operate the IC within the power dissipation. Pd-VCCxICC Io (For more information about ICC, see page 12.) VCC-VO The maximum load current Iomax for the applied voltage VCC can be calculated during the thermal design process. Calculation example Example: BD3571FP VCC = 12 V and VO = 5 V at Ta = 85 IO 0.624-12xICC IO89mA 12-5 ja=104.2/W-9.6mAW/ 25=1.2W85=0.624W (ICC=30A) Make a thermal calculation in consideration of the above so that the whole operating temperature range will be within the power dissipation. The power consumption Pc of the IC in the event of shorting (i.e., if the VO and GND pins are shorted) will be obtained from the following equation. Pc=VCCx(ICC+Ishort) www.rohm.com (c) 2011 ROHM Co., Ltd. All rights reserved. Ishort = Short current 5/9 2011.03 - Rev.B BD3570FP/HFP, BD3571FP/HFP, BD3572FP/HFP, BD3573FP/HFP BD3574FP/HFP, BD3575FP/HFP Technical Note Peripheral Settings for Pins and Precautions 1) VCC pins Insert capacitors with a capacitance of 0.33F to 1000F between the VCC and GND pins. The capacitance varies with the application. Be sure to design the capacitance with a sufficient margin. 2) Capacitors for stopping oscillation for output pins Capacitors for stopping oscillation must be placed between each output pin and the GND pin. Use a capacitor within a capacitance range between 0.1F and 1000F. Since oscillation does not occur even for ESR values from 0.001 to 100, a ceramic capacitor can be used. Abrupt input voltage and load fluctuations can affect output voltages. Output capacitor capacitance values should be determined after sufficient testing of the actual application. Operation Notes 1) Absolute maximum ratings Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure such as a fuse should be implemented when use of the IC in a special mode where the absolute maximum ratings may be exceeded is anticipated. 2) GND potential Ensure a minimum GND pin potential in all operating conditions. 3) Setting of heat Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 4) Pin short and mistake fitting 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 and GND pins caused by the presence of a foreign object may result in damage to the IC. 5) Actions in strong magnetic field Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to malfunction. 6) Testing on application boards When testing the IC on an application board, connecting a capacitor to a pin with low impedance subjects the IC to stress. Always discharge capacitors after each process or step. Be sure to turn power off when mounting or dismounting jigs at the inspection stage. Furthermore, for countermeasures against static electricity, ground the equipment at the assembling stage and pay utmost attention at the time of transportation or storing the product. 7) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. PN junction is formed by the P layer and the N layer of each element, and a variety of parasitic elements will be constituted. For example, when a resistor and transistor are connected to pins as shown in Fig. 19, the P/N junction functions as a parasitic diode when GND>Pin A for the resistor or GND>Pin B for the transistor (NPN). Similarly, when GNDPin B for the transistor (NPN), the parasitic diode described above combines with the N layer of other adjacent elements to operate as a parasitic NPN transistor. www.rohm.com (c) 2011 ROHM Co., Ltd.

The operation of parasitic elements can cause interference with circuit operation as well as IC malfunction and damage. For these reasons, it is necessary to use caution so that the IC is not used in a way that will trigger the operation of parasitic elements, such as by the application of voltages lower than the GND (P substrate) voltage to input pins. Resistor Transistor (NPN) (Pin B) B (Pin B) (Pin A) C E B C E P P+ P+ P P+ N N P N N Parasitic element GND GND P+ N Parasitic element or transistor Parasitic element or transistor N P substr t GND (Pin A) Parasitic elements Fig. 26 Example of a Simple Monolithic IC Architecture 8) Ground wiring patterns When using both small signal and large current GND patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the application's reference point so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. Be careful not to change the GND wiring pattern of any external parts, either. 9) SW Pin Do not apply the voltage to SW pin when the VCC is not applied. And when the VCC is applied, the voltage of SW pin must not exceed VCC. 10) Thermal shutdown circuit (TSD) This IC incorporates a built-in thermal shutdown circuit for the protection from thermal destruction. The IC should be used within the specified power dissipation range. However, in the event that the IC continues to be operated in excess of its power dissipation limits, the attendant rise in the chip's temperature Tj will trigger the thermal shutdown circuit to turn off all output power elements. The circuit automatically resets once the chip's temperature Tj drops. The thermal shutdown circuit operates if the IC is under conditions in express of the absolute maximum ratings. Never design sets on the premise of using the thermal shutdown circuit. (See Fig. 8) 11) Overcurrent protection circuit (OCP) The IC incorporates a built-in overcurrent protection circuit that operates according to the output current capacity. This circuit serves to protect the IC from damage when the load is shorted. The protection circuit is designed to limit current flow by not latching in the event of a large and instantaneous current flow originating 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 operation or transitioning of the protection circuits. At the time of thermal designing, keep in mind that the current capability has negative characteristics to temperatures. (See Fig. 3) www.rohm.com (c) 2011 ROHM Co., Ltd.
