Capable of driving two N-channel MOSFETs in a high-side/low-side configuration. This device enables control of two N-channel MOSFETs in half-bridge or synchronous buck topologies. With 3A peak sink and source currents and low pull-up and pull-down resistances, it drives high-power MOSFETs with minimal switching losses during MOSFET Miller plateau transitions. Since the input is independent of the supply voltage, it is compatible with both analog and digital controllers.

The input pins and HS pin withstand large negative voltages, improving system robustness. Input interlock further enhances robustness and system reliability in high-noise applications. The enable and disable functions provide additional system flexibility by reducing driver power consumption and responding to fault events within the system. The 5V UVLO allows the system to operate at lower bias voltages — a requirement in many high-frequency applications — and can improve system efficiency in certain operating modes. Small propagation delay and delay-matching specifications minimize dead-time requirements, further improving efficiency.

Both the high-side and low-side driver stages feature UVLO, forcing the outputs low when the VDD voltage falls below the specified threshold. In many applications, the integrated bootstrap diode eliminates the need for an external discrete diode, saving board space and reducing system cost. The compact package supports high-density designs.
