Key Featrues
Adaptive Non-Overlap Gate Drives: This feature ensures that the high-side and low-side MOSFETs are never turned on simultaneously, preventing shoot-through currents. This significantly enhances system reliability and efficiency, especially in motor control and switching regulator applications.
Internal Charge Pump for DC Operation: The built-in charge pump allows the driver to operate continuously without requiring external components for gate voltage boosting. This simplifies circuit design and improves performance in battery-operated or low-power systems.
Continuous Current Limit Protection: The driver monitors and limits the output current to prevent damage to the MOSFETs and the driver itself. This protection feature ensures safer operation in high-current applications, such as motor drives and inductive load control.
Auto Shutdown and Retry Capability: In the event of a fault, the driver automatically shuts down and attempts to restart after a brief delay. This self-recovery mechanism enhances system robustness and reduces the need for manual intervention in fault-prone environments.
Compatibility with Current-Sensing MOSFETs: The driver is designed to work seamlessly with current-sensing MOSFETs, enabling precise current monitoring and control. This is particularly beneficial in applications like synchronous step-down regulators and high-efficiency motor drives.
