UCC20225: support 0Hz input?

Part Number: UCC20225

Hi,

A short question. How will ucc20225 react to a DC 5V input on PWM pin? I saw the signal rate of ISO72xx can be 0 Mbps. I want to know if ucc20225 is the same.

Thanks.

    Hello Jerry,

    I am an applications engineer for the UCC20225.

    OUTA will output a high signal while OUTB will output a low signal if 5Vdc is applied to the PWM input.

    Please ensure that VCCI is greater than the 5V DC input for proper operation. Table 3 shows the logic operation of the UCC20225.

    regards,
    Mateo
