BD433 Datasheet

Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. The following are examples of safety measures: Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment.

We also recommend using reverse polarity datazheet in series or a bypass between all pins and the VCC pin. Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting.

We have now successfully completed our first stage – Opera. Low ESR ceramic capacitor can be used as output capacitor.

Transient characteristics should be sufficiently verified. Please be sure to implement, at your own responsibilities, adequate safety measures including but not limited to fail-safe design against the datasheeet injury, damage to any property, which a failure or malfunction of our Products may cause.

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

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. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.


Incorrect mounting may result in damaging the IC. As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with transportation and storage.

A customer may use this translation version only for a reference to help reading the formal version. Use both the dtasheet and reverse side of the PCB to increase the heat dissipation pattern as far as possible. In this event it also becomes impossible to determine the cause of the damage e. Otherwise bent leads may occur due to excessive stress applied when dropping of a carton.

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

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.

Baking is required before using Products of which storage time is exceeding the recommended storage time period. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes. Only includes enable input Figure 8. These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption. Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip.

In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance.

For example, in case a resistor datashete a transistor are connected to the pins as shown in the figure below then: Not connected 4 N. On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation.

Integrated thermal shutdown to protect the IC from overheating at overload conditions. ROHM shall not be in any way responsible or liable for any damages, expenses datashert losses incurred by you or datashee parties resulting from inaccuracy or errors of or concerning such information. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products.

This protection circuit is effective in preventing damage due to sudden and unexpected incidents. Please take special care under dry condition e.

Lab 9 in this note. The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. 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.
