UCC27533: IN+,IN- connection question of UCC27533

Hello Grady,

Thanks for reaching out.

We typically do not recommend connecting those pins at the gate since there is high pulsed source/sink current to turn-on and off the gate that may not be adequate for the input stage. Additionally, any reverse transients at the gate may damage the logic stage on INx. IN+ may be tied to VDD, EN and/or external circuitry controlled by the gate signal.

IN- may be tied to GND or VDD depending on the configuration.

Regards,
