The SM72295MAE/NOPB is a photovoltaic full Bridge Driver designed to drive 4 discrete N-type MOSFET's in a full bridge configuration. The drivers provide 3A of peak current for fast efficient switching and integrated high speed bootstrap diodes. Current sensing is provided by 2 transconductance amplifiers with externally programmable gain and filtering to remove ripple current to provide average current information to the control circuit. The current sense amplifiers have buffered outputs available to provide a low impedance interface to an A/D converter if needed. An externally programmable input over voltage comparator is also included to shutdown all outputs. Under-voltage lockout with a PGOOD indicator prevents the drivers from operating if VCC is too low.
