... GATE drive A voltage to drive the gate of N-channel MOSFET is generated by a built-in charge pump in the BD2270HFV. The built-in charge pump in the BD2270HFV generates a voltage three times as high as the power supply voltage at the GATE terminal. In addition, since this IC has a built-in capacitor for the charge pump, it needs no external parts. ...

... A 5V load switch can be configured like the 3.3V load switch. However, if the external N-channel MOSFET is low VGSS, clamp it with Zener diode and the like. 3. Configuration of low-voltage load switch 1.2V 3.3V Providing BD2270HFV drive power supply enables configuration of a low-voltage load switch. www.rohm.com © 2009 ROHM Co., Ltd.

... Soft start configuration 3.3V ON/OFF Connecting an external capacitor to the GATE terminal of the BD2270HFV makes it possible to slow the rise of the N-channel MOSFET, thus achieving reduction of the inrush current to the large-capacity capacitor mounted on the load side. ● Application Information This system connection diagram gives no warranty to the operation as application. ...
