In this event it also becomes impossible to determine the cause of the damage (e.g. short circuit, open circuit, etc.). Therefore, if any special mode is being considered with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered.

Within this IC, the power consumption is decided by the dropout voltage condition, the load current and the circuit current. Refer to power dissipation curves illustrated in Figure 22, 23 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at 25 °C, depending on the input voltage and the load current, chip junction temperature can be very high. Consider the design to be Tj ≤ Tjmax = 150 °C in all possible operating temperature range. Should by any condition the maximum junction temperature Tjmax = 150 °C rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient margins in the thermal design by the following method is used to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods. 1. The following method is used to calculate the junction temperature Tj from ambient temperature Ta. Tj = Ta + PC × θJA Tj : Junction Temperature Ta : Ambient Temperature : Power Consumption PC θJA : Thermal Impedance (Junction to Ambient) 2. The following method is also used to calculate the junction temperature Tj from Top Center of Case’s (mold) Temperature TT. Tj = TT + PC × ΨJT Tj : Junction Temperature TT : Top Center of Case’s (mold) Temperature PC : Power consumption : Thermal Impedance ΨJT (Junction to Top Center of Case) The following method is used to calculate the power consumption Pc (W).

We recommend using ceramic capacitor generally featuring good high frequency characteristic. When selecting a ceramic capacitor, please consider about temperature and DC - biasing characteristics. And please place capacitors near VCC – GND pin as close as possible. When input impedance is high, e.g. in case there is distance from battery, line voltage drop needs to be prevented by large capacitor. Select the capacitance according to the line impedance between the power smoothing circuit and the VCC pin. Selection of the capacitance also depends on the applications. Verify the application and allow sufficient margins in the design. We recommend using a capacitor with excellent voltage and temperature characteristics. ・Output Pin Capacitor In order to prevent oscillation, a capacitor needs to be placed between the output pin and GND pin. We recommend using a ceramic capacitor with a capacitance of 6 μF or higher. In selecting the capacitor, ensure that the capacitance of 6 μF or higher is maintained at the intended applied voltage and temperature range. Due to changes in temperature the capacitor's capacitance can fluctuate possibly resulting in oscillation. In actual applications the stable operating range is influenced by the PCB impedance, input supply impedance and load impedance. Therefore sufficient verification of the final operating environment is needed. When selecting a ceramic capacitor, we recommend using X7R or better components with excellent temperature and DC - biasing characteristics and high voltage tolerance. In case of the transient input voltage and the load current fluctuation, output voltage may fluctuate. In case this fluctuation can be problematic for the application, connect low ESR capacitor (capacitance > 6 μF, ESR < 1 Ω) in paralleled to large capacitor with a capacitance of 13 μF or higher and ESR of 5 Ω or lower. Electrolytic and tantalum and conductive polymer capacitors can be used as large capacitor. When selecting an electrolytic capacitor, please consider about increasing ESR and decreasing capacitance at cold temperature. We recommend placing the capacitor near output pin as close as possible.

Figure 27. Application Example 3 ・Reverse Polarity Diode In some applications, the VCC and pin potential might be reversed, possibly resulting in circuit internal damage or damage to the elements. For example, while the external capacitor is charged, the A point shorts to the GND. Use a capacitor with a capacitance with 1000 μF or less. We also recommend using reverse polarity diodes in series or a bypass between VO pins and the VCC. Reverse Polarity Diode Bypass Diode A Figure 28.

Reverse Connection of Power Supply Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply pins. 2. Power Supply Lines Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic capacitors. 3. Ground Voltage Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition. 4. Ground Wiring Pattern When using both small-signal and large-current ground traces, the two ground traces should be routed separately but connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal ground caused by large currents. Also ensure that the ground traces of external components do not cause variations on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance. 5. Thermal Consideration Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. Power dissipation is the value when the IC is mounted on a 114.3mm x 76.2mm x 1.57mm/1.6mm glass epoxy board. And in case this exceeds, take the measures like enlarge the size of board; make copper foil area for heat dissipation big; and do not exceed the power dissipation. 6. Inrush Current When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing of connections. 7. Testing on Application Boards When testing the IC on an application board, connecting a capacitor directly to a low-impedance output 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 the test setup during the inspection process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and storage. 8. Inter-pin Short and Mounting Errors Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin. Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge deposited in between pins during assembly to name a few. www.rohm.com .© 2016 ROHM Co., Ltd.

Unused Input Pins Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the power supply or ground line. 10. Regarding the 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 the P layers with the N layers of other elements, creating a parasitic diode or transistor. For example (refer to figure below): 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 inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be avoided. 11. Ceramic Capacitor When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with temperature and the decrease in nominal capacitance due to DC bias and others. 12. Thermal Shutdown Circuit(TSD) This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below the TSD threshold, the circuits are automatically restored to normal operation. Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage. 13. Over Current Protection Circuit (OCP) This IC incorporates an integrated overcurrent protection circuit that is activated when the load is shorted. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. www.rohm.com .© 2016 ROHM Co., Ltd. All rights reserved.
