BD4728G Rohm, BD4728G Datasheet - Page 6

• Manufacturer Part Number: BD4728G
• Description: RESET IC
• Manufacturer: Rohm

Voltage detectors
BD47xxG/FVE series need pull-up resistor in output pin. For resistance ,please confirm the level of
supply voltage pulled-up and output current capacity sufficiently, and use it to any applications.
When the capacitor for noise filtering and for delay time setting is connected to output pin,
confirm the pull-up resistance, output current capacity, capacitance of capacitor considering of the
wave rounding of the rise and decay of output.
Please be careful when the by-pass capacitor is connected between input and GND
because the transient response speed can be delayed if the extreme big capacitor is used.
