PRODUCTION DATA
The design should specify which type of input-to-output configuration should be used. If turning on the power MOSFET or IGBT when the input signal is in high state is preferred, then a device capable of the non-inverting configuration must be selected. If turning off the power MOSFET or IGBT when the input signal is in high state is preferred, then a device capable of the inverting configuration must be chosen. UCC27614DSG offers non-inverting output when IN+ pin is used as PWM input while IN- is grounded. When IN- pin is used as PWM input and IN+ is pulled high, the UCC27614DSG works as inverting output gate driver.
If ground-bouncing is a potential issue, a gate driver with negative voltage handling capability should be chosen. UCC27614 devices can handle -10-V at its input and -2-V on its output. The input of the UCC27614 devices can handle wide range of slew rate at its input and the inputs have wide hysteresis.
