Part Description: High current MOSFET driver

Part Details:

L6741 High current MOSFET driver Data Brief Features Dual MOSFET driver for synchronous rectified converters High driving current for fast external MOSFET switching High frequency operation SO8 Integrated bootstrap diode Adaptive dead-time management Description Flexible gate-drive: 5V to 12V compatible High-impedance (HiZ) management for output L6741 is a flexible, high-frequency dual-driver stage shutdown specifically designed to drive N-Channel MOSFETs connected in Synchronous-Rectified Preliminary OV protection Buck topology. Combined with ST PWM control- SO8 package lers, the driver allows implementing complete volt-age regulator solutions for modern high-current CPUs. L6741 embeds high-current drivers for both high-side and low-side MOSFETS. The Applications device accepts flexible power supply (5V to 12V) High current VRM / VRD for Desktop / Server / to optimize the gate-drive voltage for High-Side Workstation CPUs and Low-Side maximizing the System Efficiency. High current DC / DC converters The Bootstrap diode is embedded saving the use of external diodes. Anti shoot-through manage-ment avoids high-side and low-side mosfet to con-duct 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 over-comes a warning threshold protecting the load from High-Side MOSFET failures. The driver is available is SOP8 package. Table 1.
