EVAL-LT4422-AZ

EVAL-LT4422-AZ evaluation circuit showcases the LT4422, an ideal diode with integrated P-channel MOSFETs. The LT442 is designed to minimize power dissipation by regulating a 15mV forward voltage when enabled. Its fast OUT to IN reverse bias detection minimizes reverse current to prevent unwanted charging of the input source. The board features two independent LT4422 ideal diodes that share a common ground and operate over a 1.9V to 28V range. In shutdown mode, the LT4422 exhibits less than 500nA (typical) quiescent current to extend battery life. Each LT4422 is equipped with integrated P-channel MOSFETs in an ideal diode. A diode-or arrangement is used to evaluate the LT4422’s performance.
