The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current.

The absolute maximum rating of the Pd stated in this specification is when the IC is mounted on a 70mm X 70mm X 1. ROHM shall not be in any way responsible or liable for any damages, expenses or losses bs433 by you or third parties arising from the use of such information.

This protection circuit is effective in preventing damage due to sudden and unexpected incidents. Not connected 4 N. ROHM does not warrant that foregoing information or data will not infringe any intellectual property rights or datasheft other rights of any third party regarding such information or data. Low ESR ceramic capacitor can be used as output capacitor.

ROHM shall not be in any way responsible or liable for infringement of any intellectual property rights or other damages arising from use of such information or data.: Dafasheet be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the physical injury, damage to any datasueet, which a failure or malfunction of our Products may cause.

Pin Name Function Pin No. It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. The following are examples of safety measures: High output voltage accuracy: Should you intend to use this product with equipment or devices which require an extremely high level of reliability and the malfunction of which dattasheet directly endanger human life such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers bf433 other safety devicesplease be sure to consult with our sales representative in advance.

Normal operation should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature Tj will rise and the TSD circuit will be activated and turn all output pins OFF. After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation.


Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products. Ceramic capacitors can be used for compensation of the output capacitor phase. Therefore, when actually using the chip, ensure that the generated heat does not bdd433 the Pd rating. Baking is required before using Products datashet which storage time is exceeding the recommended storage time period.

Parasitic diodes inevitably occur in the structure of the IC. Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability. Incorrect mounting may result in damaging the IC.

If you intend to use our Products under any special or extraordinary environments or conditions as exemplified below datazheet, your independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: Lab 9 datashest this note.

Please take special care under dry condition e. Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND.

Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting. In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance. We have now successfully completed our first stage – Opera. If there are any differences in translation version of this datsheet formal version takes priority Application example ROHM cannot provide adequate confirmation of patents. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes.

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 datawheet design or for any purpose other than gd433 the IC from heat damage. Integrated thermal shutdown to protect the IC from overheating at overload conditions.

Therefore do not employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the P substrate GND. For example, in case a resistor and a transistor are connected to the datasheeg as shown in the figure below then: However, semiconductor products can fail or malfunction at a certain rate.

Furthermore, these ICs also feature overcurrent protection to protect the device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions. A customer may use this translation version only for a reference to help reading the formal version. In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating.

When used in sealed area, confirm the actual ambient temperature. The product described in this specification is designed to be used with ordinary electronic equipment or devices such as audio-visual equipment, office-automation equipment, communications devices, electrical appliances, and electronic toys. 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 or errors of or concerning such information.

However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment. Therefore, if bv433 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.

Documents Flashcards Grammar checker. Only includes enable input Figure 8. Therefore, in case you use datawheet 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. As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with transportation and storage.

This in order to separate the small-signal and high current dataheet 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.

Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible.
