WXNSIC NSG2011

NSG2011 is a high-voltage, high-speed power MOSFET high- and low-side gate driver IC. It features independent high-side and low-side referenced output channels. Leveraging a high-low voltage compatible process, the high- and low-side gate drive circuits are integrated on a single chip. Logic inputs are compatible with CMOS or LSTTL logic levels as low as 3.3V, and the outputs provide high-current pulse capability with shoot-through prevention dead-time logic. The floating channel supports driving of high-side N-channel power MOSFETs, with a maximum floating supply voltage of 250V. Housed in an SOP8 package, it operates over a temperature range of -40°C to 125°C. The floating channel requires an external bootstrap circuit, and both high-side and low-side channels incorporate undervoltage lockout (UVLO) protection.
