Pin Name Function Pin No.
Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND.
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.
In case of exceeding this absolute maximum rating, increase the board size and copper area to prevent exceeding the Pd rating. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. Ceramic capacitors can be used for compensation of the output capacitor phase. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes.
Baking is required before using Products of which storage time is exceeding the recommended storage time period. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment. However, semiconductor products can fail or malfunction at a certain rate. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation.
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.: 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.
Integrated thermal shutdown to protect the IC from overheating at overload conditions. In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance.
For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: Documents Flashcards Grammar checker. In this event it also becomes impossible to determine the cause of the damage e.
If there are any differences in translation version of this document formal version takes priority Application example ROHM datasheer provide adequate confirmation of patents. High output voltage accuracy: 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 or data. Also, shorts caused by dust entering between the output, input and GND pin may result in damaging the IC.
The absolute maximum rating of the Pd stated in this specification is when ddatasheet IC is mounted on a 70mm X 70mm X 1. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products.
If you intend to use our Products under any special or extraordinary environments or conditions as exemplified belowyour independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: Parasitic diodes inevitably occur in the structure of the Datasehet.
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 dataheet 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.
Low ESR ceramic capacitor can be used as output capacitor. When used in sealed area, confirm the actual ambient temperature.
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. Incorrect mounting may result in damaging the IC. Includes switch Integrated overcurrent protection to protect the IC from damage caused datadheet output short-circuiting.
It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. Normal operation should be within the power dissipation rating, if datxsheet 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.
We have now successfully completed our datashet stage – Opera. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible.
Not connected 4 N. These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption. The following bd4433 examples of safety measures: A customer may use this translation version only for a reference to help reading the formal version. As a protection from static electricity, nd433 that the assembly setup is grounded and take sufficient caution with transportation and storage. 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.
After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. Only includes enable input Figure 8. Lab 9 in this note. Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance datasheey reliability.
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. Please 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 property, which a failure or malfunction of our Products may cause.
Please take special care under dry condition e. This protection circuit is effective in preventing damage due to sudden and unexpected incidents. 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.
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.
Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating. Transient characteristics should be sufficiently verified.
We also recommend using reverse polarity diodes in series or a bypass between all pins and the VCC pin. Therefore, if any special mode is being considered with values expected to exceed the absolute maximum ratings, implementing bd4333 safety measures, such as adding fuses, should be considered.
