FEATURES  
DESCRIPTION  
The LM2724A is a dual N-channel MOSFET driver

•
Shoot-Through Protection  
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.
