The Gate pull-up current of LT4356 is specified at -4.5uA (min), -30uA(typ), -50uA(max) for Vgate = 48V, Vcc =48V. I was wondering under what conditions the gate pull-up current can drop to -4.5uA.

Thanks,

Min

Hi Min,

The Gate pull variation depends on Temperature and Supply voltage along with part-to-part variation.

The following plot (from datasheet Pg. 6) depict the gate pull-up current variation with temperature and Vcc.

The worst case corner is expected at lower Vcc and high temperature.
