●The LM2725/LM2726 is a family of dual MOSFET drivers that drive both the top MOSFET and bottom MOSFET in a push-pull structure simultaneously. It takes a logic level PWM input and splits it into two complimentary signals with a typical 20ns dead time in between. The built-in shoot-through protection circuitry prevents the top and bottom FETs from turning on simultaneously. With a bias voltage of 5V, the peak sourcing and sinking current for each driver of the LM2725 is about 1.2A and that of the LM2726 is about 3A. In an SOIC-8 package, each driver is able to handle 50mA average current. When EN signal is asserted the 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 the driver outputs and will not turn on a driver until the other driver output is low. The top gate bias voltage needed by the top MOSFET can be obtained through an external bootstrap structure. Minimum input pulse width is as low as 55ns.
