DESCRIPTION
The LM2724A is a dual N-channel MOSFET driver
which can drive both the top and bottom MOSFETs in
a push-pull structure simultaneously. The LM2724A
takes a logic input and splits it into two complimentary
signals with a typical 20ns dead time in between. The
built-in cross-conduction protection circuitry prevents the top and bottom MOSFETs from turning on
simultaneously. With a bias voltage of 5V, the peak
sourcing and sinking current for each driver of the
LM2724A is about 3A. Input UVLO (Under-Voltage-
Lock-Out) ensures that all the driver outputs stay low
until the supply rail exceeds the power-on threshold
during system power on, or after the supply rail drops
below power-on threshold by a specified hysteresis
during system power down. The cross-conduction
protection circuitry detects both driver outputs and will
not turn on a driver until the other driver output is low.
The top gate voltage needed by the top MOSFET is
obtained through an external boot-strap structure.
When not switching, the LM2724A only draws up to
195μA from the 5V rail. The synchronization
operation of the bottom MOSFET can be disabled by
pulling the SYNC pin to ground.
