I am a searching for a single supply high speed OpAmps to drive a MOSFET Push-Pull Stage of an Inverter Gate Drive.
The OpAmps are to be configured in voltage feedback configuration to drive the MOSEFTs to switch variable currents from 0 - 21A.
Previously, I used LM7171 for this purpose, which are unfortunately not Automotive Qualified.
Could you please suggest the alternate to LM7171 OpAmps which are additionally AEC qualified or any other suitable OpAmp for this application.
In reply to Sean Cashin:
Thank you for your reply. Unfortunately, I am working exclusively with Automotive Qualified components.
In reply to Rohit Bhat:
Thank you for your reply.
The End Application is a Gate Drive of an IGBT Module in Totem Pole configuration in automotive applications.
The OpAmp drives the Mosfet to control the charging/ discharging current of an IGBT in voltage feedback configuration.
I am only allowed to use automotive qualified componenets for this application and I already have used LM7171 for non-automotive application. This is the reason I am searching closest possible match.
I had found THS4041-Q1 on your website in high speed OpAmps.
Although it is Single Supply suitable and works well with single positive supply, it doesn't work however with single negative supply.
I simulate the OpAmp with Spice modell given on your website in LtsSpice.
