MF2007SW
[under development] High-side gate driver with built-in reverse current protection function |
An Nch_MOSFET gate driver IC with built-in reverse current protection function. Combination with an externally connected Nch_MOSFET achieves low dissipation and downsizing compared to conventional diodes (SBD) in reverse connection and reverse current prevention applications. Can also be used as a bidirectional conduction ON/OFF switch (for semiconductor relays, etc.). |
Heat generation/dissipation reduction |
Aims to reduce heat generation and dissipation compared to SBD by utilizing MOSFET. Heat generation and dissipation are dependent upon externally connected Nch_MOSFET. |
Selectable Reverse Current Protection Function |
The reverse current protection function can be switched ON and OFF via the REV terminal Hi/Lo status. No function : Bidirectional conduction is possible. |
Wide input voltage range |
Compatible with a wide range of input voltages from 3.5 to 70V, which allows for use in a wide range of devices. |
