• Fast Transient Microprocessors built-in cross-conduction protection circuitry prevents
the top and bottom FETs from turning on
simultaneously. The cross-conduction protection
circuitry detects both the driver outputs and will not
turn ona driver until the other driver outputis low.
Witha bias voltageof 5V, the peak sourcing and
sinking current for each driver of the LM2722is
typically 3A.In an SOIC-8 package, each driveris
ableto handle 50mA average current. Input UVLO
(Under-Voltage-Lock-Out) forces both driver outputs
low to ensure proper power-up and power-down
operation. The gate drive bias voltage neededby the
high side MOSFETis obtained through an external
bootstrap. Minimum pulse widthisas lowas 55ns.
