The FOD3150TS Isolators - Gate Drivers is specifically designed to drive a wide variety of power field-effect transistors (FETs) quickly and robustly. The FOD3150TS utilizes precision automatic voltage control (AVC) to maintain a constant voltage for gate driving, ensuring that the power FETs will not be damaged due to sudden surge voltages. An extra unique feature of the FOD3150TS is the integrated current sensing and protection circuit, which provides robust protection against over-current. This device can operate at a wide range of temperatures, making it an ideal solution for extremely harsh conditions.

The FOD3150TS has a wide selection of applications, especially in industrial systems and home appliance. Its power FETs are used in high performance H-bridge circuits for driving motors or pumps. This device is also used to drive high current MOSFETs for ON/OFF switching of household appliances, industrial equipment, and power supplies. In addition, its current sensing and protection capability makes it an ideal choice for over-current protection in automotive, aerospace, and medical industry.

The FOD3150TS Isolators - Gate Drivers can be powered by 24V to 100V external supply. It incorporates two separate power supplies: the low-voltage power supply (Vcc) and the high-voltage supply (Vdd). The low-voltage supply provides the necessary power to the control logic, while the high-voltage supply supplies the gate drive. The voltage of the high-voltage supply can be adjusted from 4.0V to 28V.

The FOD3150TS Isolators - Gate Drivers implements a precision AVC circuit to drive the power FETs at a constant voltage. The AVC circuit monitors the gate voltage and, when voltage drops to a certain level, the AVC circuit provides a higher voltage to the gate to ensure that the FET is driven to full Vgs. The AVC circuit also ensures that the FET is not driven higher than the maximum rated Vgs, protecting it from damage due to surge voltages.

The FOD3150TS also features an integrated current sensing and protection circuit. This circuit senses the current delivered to the FET and, when the current exceeds a predetermined level, the circuit will shutdown the FET safely. This provides robust protection against over-current in applications that require very high-currents. The current sensing circuit is also useful for diagnostics and fault analysis in these applications.

Overall, the FOD3150TS Isolators - Gate Drivers is an efficient and reliable solution that provides robust protection against over-current and surge voltages. Its wide range of applications and reliable performance make it an ideal solution for industrial systems and home appliance.
