EVAL-LT4423-AZ

製品概要

The EVAL-LT4423-AZ evaluation circuit showcases the LT4423, an ideal diode with integrated back to back P-channel MOSFETs and a load switch 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 integrated thermal detection offers additional protection against over thermal conditions by disabling the power path.

The board features two independent LT4423 ideal diodes and load switches that share a common ground and operate over a 1.9V to 28V range.

Use the SHDN input to turn on and off power to the load. In shutdown mode, the LT4423 exhibits less than 500nA (typical) quiescent current to extend battery life. Design files for this circuit board are available.
