Searching a high-side driver ic for a p-channel MOSFET, do you know any?

SiliconWizard:
You're mentioning an integrated switch, with of course its own limitations and compromises, but I think it won't be too hard to find a separate gate driver that can handle switching @10kHz.

Scrts:
Check TI, e.g.: http://www.ti.com/lit/ds/symlink/tps22990.pdf

But in general... switching 10A @ 10kHz is quite a challenge :box:

Hello guys,

in order to shine some light on the task at hand I want to explain what I am actually doing.
The pcb I'm designing is for use in a testing/evaluation laboritory.
We are testing valves/clutches. In this context they use a technique called "peak and hold" where first you drive the valve at full power (which could be up to 10A) in order to bring it in position. After this first phase the duty cycle is reduced to say 30% -40% in order to hold it in place.
Since I do not know exactly what kind of valve will be connected I need to plan for a wide range of supply voltages (8 - 32V), pwm-frequencies (0 - 10kHz), duty cycles (0 - 100%).
The testbox Im building will take to analog voltages from 0 - 10V in order to set the frequency as well as the duty cycle. Im planning to use some avr mcu like the attiny for this task.


Answer to Scrts: Unfortunately the operating voltage range is only up to 6V. But thank you very much for bringing it to my attention anyway.

Cudos to Ian M.
I took a look at your suggested driver circuit and was blown away.
Clearly you are a very experienced analog engineer. The suggested circuit far exceeds my limited knowlege.
It features extremly fast switching times which I think are in this case to fast. I'm worried about EMV and since I only need to switch at 10kHz maybe 100kHz this circuit seems to be a bit overkill.

On the other hand I would be very interested in how the circuit works.
If you could ever so kindly find the time to explain to me the reason for implementing the matched pair, the two schottky diodes aswell as the general idea, I would be very thankfull.

Thank you all for your time and have a good day.
Greetings from Germany

Scrts:
The question is: if you are doing a tester for a device, then what chip drives that device in the real application? Reusing the same circuitry would make your tester even better.

SiliconWizard:
Another tip for an integrated gate driver is to look for half-bridge drivers instead (and obviously just use the upper driver and a NMOS transistor, although you may find some use for the lower switch as well). I think you'll have more options for fast switching (which means higher peak output current) than with single gate drivers, as half-bridge drivers are specifically targeted at PWM applications such as motor driving, so fast switching.
