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.
