The RS8801 single-channel, high-speed, low-side gate driver device is capable of effectively driving MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, the RS8801 is capable of sourcing and sinking high peak-current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation delay typically 11ns.

The RS8801 device is capable of handling -4V at input. The RS8801 provides 5A source and sink peak-drive current capability at VDD = 12V.

The RS8801 is designed to operate over a wide VDD range of 4.5V to 18V and wide temperature range of –40°C to 140°C. Internal Undervoltage Lockout (UVLO) circuitry on VDD pin holds output low outside VDD
operating range. The capability to operate at low voltage levels such as below 5V, along with best-in-class switching characteristics, is especially suited for driving emerging wide band-gap power-switching devices as GaN power semiconductor devices.

The RS8801 series is available in Green SOT23-5 packages. It operates over an ambient temperature range of -40°C to +140°C.
