Furthermore, if the temperature exceeds Tjmax, element deterioration or damage may occur. Implement proper thermal designs to ensure that the power dissipation is within the permissible range in order to prevent instantaneous IC damage resulting from heat and maintain the reliability of the IC for long-term operation. Refer to the power derating characteristics curves in Fig. 29. ・Power Consumption (Pc) Calculation Method Vcc IP Vcc 3.3 V output IO1 ・Power consumption of 3.3V power transistor: Power Tr Vo1 Pc1 = (Vcc − 3.3)  Io1 Controller Vcc ・Power consumption of Vo2 power transistor: I Vo2 Power Tr Pc2 = (Vcc − Vo2)  Io2 Icc 1.5 V output or ・Power consumption due to circuit current: 1.8 V output GND Pc3 = Vcc  Icc →Pc = Pc1 + Pc2 + Pc3 Refer to the above and implement proper thermal designs so that the IC will not be used under excessive power dissipation conditions under the entire operating temperature range. O2 *Vcc: Applied voltage Io1: Load current on Vo1 side Io2: Load current on Vo2 side Icc: Circuit current * The Icc (circuit current) varies with the load. (See reference data in Figs. 2, 3, 14, and 15.) ・Calculation example (BA33D15HFP) Example: Vcc = 5V, Io1 = 200mA, and Io2 = 100mA ・Power consumption of 3.3V power transistor: Pc1 = (Vcc − 3.3)  Io1 = (5 − 3.3)  0.2 = 0.34W ・Power consumption of 1.5V power transistor: Pc2 = (Vcc − 1.5)  Io2 = (5 − 1.5)  0.2 = 0.35W ・Power consumption due to circuit current: Pc3 = Vcc  Icc = 5  0.0085 = 0.0425 (W) (See Figs. 14 and 15) Implement proper thermal designs taking into consideration the dissipation at full power consumption (i.e., Pc1 + Pc2 + Pc3 = 0.34 + 0.35 + 0.0425 = 0.7325W). ●Explanation of External Components ○BA3258HFP 1) Pin 1 (Vcc pin) Connecting a ceramic capacitor with a capacitance of approximately 3.3F between Vcc and GND as close to the pins as possible is recommended. 2) Pins 4 and 5 (Vo pins) Insert a capacitor between the Vo and GND pins in order to prevent output oscillation. The capacitor may oscillate if the capacitance changes as a result of temperature fluctuations. Therefore, it is recommended that a ceramic capacitor with a temperature coefficient of X5R or above and a maximum capacitance change (resulting from temperature fluctuations) of 10% be used. The capacitance should be between 1F and 1,000µF. (Refer to Fig. 30) ○BA33D□□Series 1) Pin 1 (Vcc pin) Insert a 1F capacitor between Vcc and GND. The capacitance will vary depending on the application. Check the capacitance with the application set and implement designing with a sufficient margin. 2) Pins 4 and 5 (Vo pins) Insert a capacitor between the Vo and GND pins in order to prevent oscillation. The capacitance may vary greatly with temperature changes, thus making it impossible to completely prevent oscillation. Therefore, use a tantalum aluminum electrolytic capacitor with a low ESR (Equivalent Serial Resistance). The output will oscillate if the ESR is too high or too low, so refer to the ESR characteristcs in Fig. 31 and operate the IC within the stable operating region. If there is a sudden load change, use a capacitor with higher capacitance. A capacitance between 10F and 1,000F is recommended.

All rights reserved. 6/8 2011.03 - Rev.B BA3258HFP,BA33D15HFP,BA33D18HFP Technical Note ●Notes for use 1) Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. 2) GND voltage The potential of GND pin must be minimum potential in all operating conditions. 3) Thermal Design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 4) Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. 5) Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic 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. Always turn the IC's power supply off before connecting it to or removing it from a jig or fixture during the inspection process. Ground the IC during assembly steps as an antistatic measure. Use similar precaution when transporting or storing the IC. 7) Regarding input pin of the IC This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used. 8) Ground Wiring Pattern 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 ground potential of application 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 components, either. 9) Thermal Shutdown Circuit (TSD) This IC incorporates a built-in thermal shutdown circuit for protection against thermal destruction. Should the junction temperature (Tj) reach the thermal shutdown ON temperature threshold, the TSD will be activated, turning off all output power elements. The circuit will automatically reset once the chip's temperature Tj drops below the threshold temperature. Operation of the thermal shutdown circuit presumes that the IC's absolute maximum ratings have been exceeded. Application designs should never make use of the thermal shutdown circuit. 10) Overcurrent protection circuit An overcurrent protection circuit is incorporated in order to prevention destruction due to short-time overload currents. Continued use of the protection circuits should be avoided. Please note that the current increases negatively impact the temperature. 11) Damage to the internal circuit or element may occur when the polarity of the Vcc pin is opposite to that of the other pins in applications. (I.e. Vcc is shorted with the GND pin while an external capacitor is charged.) Use a maximum capacitance of 1000 mF for the output pins. Inserting a diode to prevent back-current flow in series with Vcc or bypass diodes between Vcc and each pin is recommended.
