120V Half-bridge Gate Driver
NSD1224x is a powerful 120V half-bridge gate driver. With peak source/sink current of 3A/-4A and low Rdson of inside ON/OFF MOSFET, it can drive high-power MOSFETs with very low switching losses. The NSD1224x input pin and SW pin can withstand large negative voltage to improve system reliability. The input interlock function prevents the short-through from high-side and low-side MOSFETs in bridge topologies The undervoltage locking (UVLO) is available in both the high-side and low-side drivers. The small communication delay and channel to channel delay matching provide more dead time design margin, further improve efficiency. NSD1224x integrates a built-in bootstrap diode, requiring no external separate diode to save layout space and reduce system costs.
