Simple N-channel MOSFET driver

[Pax Writer]

Hi guys

This is probably a silly question. I'll try anyway, though.
I need to switch an IRF3205 with my ATTiny45. The processor is (of course) on +5V, the transistor is on +10V and so I need a driver between the two.
The thing is that space is an issue, so I was hoping to find a simple DIP4-sized IC or similar. My imaginary chip has PWR, GND, IN and OUT and that's it.
Is there such a thing?
If not, what would you suggest I do to be able to switch the transistor.
Note: The transistor will be used in PWM-mode at low to moderate speed 500Hz-50kHz, I imagine.

Thanks in advance.

Go to International Rectifier Home Page - Flash Detection and look for
General Purpose ICs

The smallest that I see are 8-pins.

The IRS4426/IRS4427/IRS4428 are 8 pins with 2 drivers per package.

Good tip, although rather general.
I found the ICL7667 at a local shop and I think that'll do. Apparently single driver DIP4 never really took off, so I'll make do with a DIP8.
Thanks.

Hi Pax Writer,

if space is an issue why not use a logic level MosFet such as the BUK9Y09-40B (NXP semi) (40V/75A)?

It is manufactured with a SOT669 (LFPAK) package.

That transistor has over 2000pF gate capacitance and can not be driven at 50kHz from a microprocessor output.

I forgot to mention that by small, I meant the smallest possible leaded component. I guess I subconsciously assumed that everybody would just know
Anyway, thanks for your advice. That also includes the final two posts which gave me food to thought, especially regarding the gate capacitance vs. inrush current.
