UCC27533DBVT

The UCC27533DBVT is a 35Vmax VDD Single Channel Driver that can effectively drive MOSFET and IGBT power switches. Using a design that allows for a source of up to 2.5 and 5A sink through asymmetrical drive (split outputs), coupled with the ability to support a negative turn-off bias, rail-to-rail drive capability, extremely small propagation delay (17ns typical), the UCC27533 device is ideal solution for MOSFET and IGBT power switches. The UCC27533 can also support enable, dual input and inverting and non-inverting input functionality. The split outputs and strong asymmetrical drive boost the devices immunity against parasitic Miller turn-on effect and can help reduce ground debouncing. The logic behaviour of the driver is shown in the application diagram, timing diagram and input and output logic truth table. Internal circuitry on VDD pin provides an under-voltage lockout function that holds output low until VDD supply voltage is within operating range.
