BD2270HFV_09 Datasheet, PDF (1/13 Pages) Rohm – MOSFET Controller IC for Load Switching

Power Management Switch IC Series for PCs and Digital Consumer Product
MOSFET Controller IC
for Load Switching
BD2270HFV
No.09029EAT01
●Description
The BD2270HFV is an IC with a single built-in external N-channel MOSFET driver circuit. This IC has a built-in charge
pump circuit for gate drive and output discharge circuit, enabling configuration of a high side load switch for N-channel
MOSFET drive without using any external parts.
In addition, the control input terminal has a built-in comparator with hysteresis function, facilitating control of the power up
sequence. The space saving type of HVSOF5 package is used.
●Features
1) Built-in charge pump
2) Built-in discharge circuit for output charge
3) Soft start circuit
4) Built-in comparator with hysteresis function at control input terminal
5) Compact HVSOF5 package
6) Operating current 50μA
7) Standby current 5μA
8) Possible to drive N-channel power MOSFET
●Applications
PCs, PC peripheral devices, digital consumer electronics, etc.
