UCC2818 OVP/EN pin bias current

Other Parts Discussed in Thread: UCC2818

Hello,

Bias current at OVP/EN pin of UCC2818 is unspecified. Looking at the block diagram, one could assume that bias current is very small. However, from a sample circuit I measure 45 uA. That definitely cannot be ignored. Would there be min/typ/max values available?

Best regards,

Antti

    Sorry about a mistake.

    Eventually I found an error in my pin current calculation. Actual current is negligible.

    Still I miss a specification, because I would like to use the largest possible resistor values in voltage division.

    BR, Antti
