The RS8802 dual-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 RS8802 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 13ns.

The RS8802 device is capable of handling -4V at input. In addition, the drivers feature matched internal propagation delays between the two channels, these delays are very well suited for applications requiring dual-gate drives with critical timing, such as synchronous rectifiers. This also enables connecting two channels in parallel to effectively increase currentdrive capability or driving two switches in parallel with one input signal.

The RS8802 provides 5A source and 5A sink (symmetrical drive) peak-drive current capability at VDD = 12V.

The RS8802 is designed to operate over a wide VDD range of 4.5 V to 18 V 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-inclass switching characteristics, is especially suited for driving emerging wide band-gap power-switching devices as GaN power semiconductor devices.
