MOSFET drivers
Integrated discrete MOSFET drivers combine several discrete products into one package to offer MOSFET
driving functionality. With a choice of con鏗乬urations Philips offers solutions to take load from the driving circuit,
improve the ef鏗乧iency of the MOSFET and enable design 鏗俥xibility.
Key features
- Complete MOSFET driving functionality in
one package
- Several con鏗乬urations available
Key bene鏗乼s
- Improved MOSFET ef鏗乧iency by
鈥?Minimizing rise and fall time
鈥?Fast gate (dis-)charge of the driven
MOSFET
- Takes load from the driving circuit
and thus minimizes the IC power dissipation
- More design 鏗俥xibility: the control IC and
the MOSFET do not have to be placed as
close as possible anymore
- Cost-effective alternative to IC-solutions
Key applications
- MOSFET driver
- Bipolar power transistor driver
- Push-pull driver
