Trying to supply power with a standard converter/regulator topology inevitably leads to component failure, insufficient power delivery, or an oversized system with low efficiency.įor moderate to high DC power delivery, a bridge topology is a better choice, specifically a full-bridge topology with MOSFETs. Many designers that work on lower power systems may be tempted to try and scale a lower power converter topology to a higher power system, but this does not work out in the designer’s favor. Power delivery with stable DC voltage and current is critical for power regulators/converters, motor drivers, and other applications like lighting and pulse generation circuits. The functions contained are the input stages, UVLO protection, level shift, bootstrap diode, and output driver stages.Full-bridge MOSFET driver components can be used in high-side switching regulators or motor drive circuits. The low-side driver is referenced to VSS which is typically ground. The high-side driver is referenced to the switch node (HS) which is typically the source pin of the high-side MOSFET and drain pin of the low-side MOSFET. The bootstrap diode for the high-side driver bias supply is integrated in the chip. The PWM input signal (high level) can be 3.3 V, 5 V or up to V DD logic input to cover all possible applications. In the dual gate driver, the high side and low side each have independent inputs which allow maximum flexibility of input control signals in the application. The floating high-side driver is capable of operating with supply voltages of up to 80 V. The high speed dual gate driver are designed to drive both the high-side and low-side of N-Channel MOSFETs in a half bridge or synchronous buck configuration. The driver IC features low delay time and matched PWM input propagation delays, which further enhance the performance of the part. The FAN8811 integrates a driver IC and a bootstrap diode. The FAN8811 is high side and low side gate-drive IC designed for high-voltage, high-speed, driving MOSFETs operating up to 80V. AEC/PPAP Automotive Process Documentation.
