for High Side NMOSFET
BD2270HFV-LB
General Description
This is the product guarantees long time support in
Industrial market.
BD2270HFV is an IC with a 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
Long time support a product for Industrial
applications.
Built-in charge pump
Built-in discharge circuit for output charge
Soft start circuit
Built-in comparator with hysteresis function at
control input terminal
Possible to drive N-channel power MOSFET
Applications
Industrial Equipment, PCs, PC peripheral devices,
digital consumer electronics, etc.
