Thread Summary

                The user asked for clarification on the Vout(PG_THRESHOLD) equation for the LT83402. The final answer confirmed a typo: the divider should be multiplied by 0.5V before adding to the product of (Ipgfb x Rrpgfb(top)).

Hi ADI


Please can you clarify or confirm the equation for Vout(PG_THRESHOLD) shown in the datasheet on page 36 for the LT83402?


Thanks
