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.
