To prevent the functional deterioration or thermal damage of semiconductor devices and ensure their service
life and reliability, they must be designed and reviewed in such a way that the absolute maximum rating can
not be exceeded in any cases or even at any moment.
Two output types can be used. One is BD48XXG/FVE (Fig.3) of open drain output type, and the other is
BD49XXG/FVE (Fig.4) of CMOS output type.
• Operating temperature range
The circuit function is guaranteed within the temperature range. However, the operating characteristics
are different from that of Ta=25°C. If they are any questions about the extent of guarantee of circuit
functions in this operating temperature range, please ask for more technical information.
• Output voltage
V
OUT
pin voltage should not exceed the indicated value. For Nch open drain output type, V
DD
applied
voltage and V
OUT
pin H output voltage can be used independently. Both of them should not exceed the
each indicated value.
• Power supply voltage
This voltage is the applied voltage between V
DD
and GND. The applied voltage should not exceed the
indicated value.
• Storage temperature range
This IC can be stored up to this temperature range without deterioration of characteristics. However,
an abrupt thermal shock of extreme temperature fluctuations may cause the deterioration of characteristics.
