Description

The UCC27511 and UCC27512 single-channel, high-speed, low-side gate-driver device can effectively drive MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC27511 and UCC27512 are capable of sourcing and sinking high peak-current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation delay, typically 13 ns.
UCC27511 features a dual-input design which offers flexibility of implementing both inverting (IN– pin) and noninverting (IN+ pin) configuration with the same device. Either IN+ or IN– pin can be used to control the state of the driver output. The unused input pin can be used for enable and disable functions. For safety 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 UCC27511 device is based on TTL and CMOS-compatible low-voltage logic which is fixed and independent of the VDDsupply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.
The UCC27511 and UCC27512 provides 4-A source, 8-A sink (asymmetrical drive) peak-drive current capability. Strong sink capability in asymmetrical drive boosts immunity against parasitic, Miller turnon effect. The UCC27511 device also features a unique split output configuration where the gate-drive current is sourced through OUTH pin and sunk through OUTL pin. This unique pin arrangement allows the user to apply independent turnon and turnoff resistors to the OUTH and OUTL pins respectively and easily control the switching slew rates.
UCC27511 and UCC27512 are designed to operate over a wide VDDrange of 4.5 to 18 V and wide temperature range of –40°C to 140°C. Internal Undervoltage Lockout (UVLO) circuitry on VDDpin holds output low outside VDDoperating range. The capability 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.
