Hello,
I'm testing my chip right now.
But it doesn't work ideally, so for the operation, I connect the external source to sepecific pad.
I connected function generator and applied pulse (D=50%, 10kHz, 0V-5V, supply=5V circuit) signal.
But at some point, the chip stops working.
Inside the chip, there is no buffer and ESD between the pad and the output node. It's just a direct metal-to-metal connection.
And it works well at first, and then it doesn't work anymore.
After a few iterations of swapping out the probe that connects to the pad, I think there's something physically wrong with the pad.
But is this really possible?
The pad is connected to the drain of the front-end MOSFET and the source of the back-end MOSFET.
