WXNSIC NSG2065

The NSG2065 is a three-phase high-voltage power MOSFET and IGBT gate driver capable of simultaneously driving the gates of both high-side and low-side power transistors. The floating channel drive design supports bus voltages up to 250V. The NSG2065 output delivers strong drive capability, with source/sink output currents up to 1.2A/1.5A. The NSG2065 operates over a wide supply voltage range, with independently optimizable high-side and low-side gate drive voltages for maximum drive efficiency. Internal shoot-through protection and dead-time circuitry prevent simultaneous conduction of both transistors, further reducing switching losses. The UVLO function of the NSG2065 ensures both driver outputs are held low when the supply voltage is insufficient. The NSG2065 integrates a bootstrap diode to minimize external peripheral components.
