The UCC27517A-Q1 single-channel high-speed low-side gate-driver device effectively drives MOSFET and IGBT power switches. With a design that inherently minimizes shoot-through current, the UCC27517A-Q1 sources and sinks high peak-current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation delay typically 13 ns.
The UCC27517A-Q1 device handles –5 V at input.
The UCC27517A-Q1 provides 4-A source and 4-A sink (symmetrical drive) peak-drive current capability at VDD = 12 V.
The UCC27517A-Q1 operates 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 the output low outside VDD operating range. The ability to operate at low voltage levels such as below 5 V, along with best-in-class switching characteristics, is especially suited for driving emerging wide band-gap power-switching devices such as GaN power-semiconductor devices.

UCC27517A-Q1 features a dual-input design which offers flexibility of implementing both inverting (IN– pin) and non-inverting (IN+ pin) configurations with the same device. Either the IN+ or IN– pin are used to control the state of the driver output. The unused input pin is used for the enable and disable functional. For protection purpose, internal pullup and pulldown resistors on the input pins ensure that outputs are held low when input pins are in floating condition. Hence the unused input pin is not left floating and must be properly biased to ensure that driver output is in enabled for normal operation.
The input-pin threshold of the UCC27517A-Q1 device is based on TTL and CMOS compatible low-voltage logic which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.
