MP6540HUG's Current-sense Amplifier frequency characteristics

To support,

I would like to know more about your product of MP6540HGU-Z.
It has three built-in current-sense amplifiers.
What is the range of frequency characteristics?

Regards,
Kunihiro

An update with results would be greatly appreciated.

Hello,

For Vin=50V and Ipeak=5A, 100kHz seems to be the max that the device can respond to. The device has shown to hit OTP at these conditions.

The current sense function has 2us setting time, so please set a sample delay for the SOX output for 2us after LS-FET turns on for any phase.

Thank you,
Vinh Tran
