L6741 High current MOSFET driver

L6741 is a flexible, high-frequency dual-driver specifically designed to drive N-channel MOSFETs connected in Synchronous-Rectified Buck topology. Combined with ST PWM controllers, the driver allows implementing complete voltage regulator solutions for modern high-current CPUs. L6741 embeds high-current drivers for both high-side and low-side MOSFETS. The device accepts flexible power supply (5V to 12V) to optimize the gate-drive voltage for High-Side and Low-Side maximizing the System Efficiency.

The Bootstrap diode is embedded saving the use of external diodes. Anti shoot-through management avoids high-side and low-side mosfet to conduct simultaneously and, combined with Adaptive Dead-Time control, minimizes the LS body diode conduction time.

L6741 embeds Preliminary OV Protection: after VCC overcomes the UVLO and while the device is in HiZ, the Low-Side MOSFET is turned ON to protect the load in case the output voltage overcomes a warning threshold protecting the load from High-Side MOSFET failures.

The driver is available is SOP8 package
