DESCRIPTION
The SM72295 is 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.
