Bipolar Work Around for the MAXREFDES74#

筆者: John Greene

要約: The MAXREFDES74# allows for both unipolar and bipolar modes of operation from a single +15V to +20V DC source. The unipolar mode operates as expected; however, the bipolar mode contains a potential power sequencing issue upon startup if J6 is in position 1-2. This app note discusses the cause of the problem and several work arounds to get the board functioning upon startup.
