Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. Parasitic diodes inevitably occur in the structure of the IC.

ROHM does not warrant that foregoing information or data will not infringe any intellectual property rights or any other rights of any third party regarding such information datashet data.

Although the actual application might datashewt the cause of the transients, the IC input voltage, output current and temperature are also possible causes. When used in sealed area, confirm the actual ambient temperature. We also recommend using reverse polarity diodes in series or a bypass between all pins and the VCC pin.

ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties resulting from inaccuracy dataasheet errors of or concerning such information. We have now successfully completed our first stage – Opera.

However, semiconductor products can fail or malfunction at a certain rate.

Should you intend to use this product with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devicesplease be sure to consult with our sales representative in advance.


Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition xatasheet negatively affect product performance and reliability.

Includes switch Integrated overcurrent protection to protect the Bd343 from damage caused by output short-circuiting.

It is strongly recommended to confirm solderability before using Products of which storage time dafasheet exceeding the recommended storage time period. A customer may use this translation version only for a reference to help reading the formal version.

BD datasheet & applicatoin notes – Datasheet Archive

The following are examples of safety measures: Only includes enable input Figure 8. Ceramic capacitors can be used for compensation of the output capacitor phase. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible. Low ESR ceramic capacitor can be used as output capacitor. Also, shorts caused by dust entering between the output, input and GND pin may result in damaging the IC. Transient characteristics should be sufficiently verified.

For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip.

High output voltage accuracy: Therefore, if any special mode is being dxtasheet with values expected to exceed the absolute maximum ratings, implementing physical safety measures, such as adding fuses, should be considered.


After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation.

Therefore, in case you use such information, you are solely responsible for it and you must exercise your own independent verification and judgment in the use of such information contained in this document.

In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating.

In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance. ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of such information. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.

The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm X 70mm X 1. This in order to separate the small-signal and high current patterns and to ensure that voltage changes stemming from the wiring resistance and high current do not cause any voltage change in the small-signal GND.

The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Pin Name Function Pin No.
