Original question:

UCC21750: is this N-MOSFET or P-MOSFET? what's the body diode direction?

UCC21750: Sink/Source Current

Part Number: UCC21750

1. In D/S, it specifics that the sink/source current with certain condition is +/-10A. Is this a minimum current? What's the condition of the VDD-VEE with +/-10A?

Is there diagram chart to show the gate driving capability current vs. VDD-VDD(V)?

2. If ext. Miller Clamp function is not used, how to deal with CLMPI pin for good noise immunity?

3. If both APWM and AIN are not used, how to deal with them for good noise immunity?

Regards

    Hello Brian,

    1. The spec is tested across VDD and VEE combinations as given at the top of the page above the Electrical Characteristics table, VDD-COM = 20V, 18V, and 15V, and COM-VEE= 0V, 5V, and 8V.

    2. If CLMPI (internal miller clamp) isn't used, best thing is to tie it to VEE.

    3. AIN should be tied to COM if not being used. APWM can be floating or connected to a capacitor to connected to GND.
