LM2724A
High Speed 3A Synchronous MOSFET Driver
General 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 struc-
ture. 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.
