Hai Micro_brain
You may use IRF 5305, IRF4905, IRF9520, IRF9530 and many more you'll find on

Hi,
For High Side Drive, you require a High Side Driver as High Side requires Virtual Ground. If frequency is low,you can drive with discreet driver with P channel and N channel Mosfets. But for High frequency, don't try with discreet driver,use high side driver. Thanks.
