The UCC53x0 is a family of simple, isolated gate drivers for power semiconductor devices, such as MOSFETs, IGBTs, or SiC MOSFETs. The family of devices is intended for use in applications such as motor control, solar inverters, switched-mode power supplies, and industrial inverters.
The UCC53x0 family of devices has three pinout configurations, featuring split outputs, Miller clamp, and UVLO with reference to GND2. The UCC5320SC, UCC5350SB, and UCC5390SC have a split output, OUTH and OUTL. The two pins can be used to separately decouple the power transistor turnon and turnoff commutations. The UCC5310MC and UCC5350MC feature active Miller clamping, which can be used to prevent false turn-on of the power transistors induced by the Miller current. The UCC5320EC and UCC5390EC offer true UVLO protection by monitoring the voltage between the VCC2 and GND2 pins to prevent the power transistors from operating in a saturation region. The UCC53x0 family of devices comes in an 8-pin D and 8-pin DWV package options and have a creepage, or clearance, of 4 mm and 8.5 mm respectively, which are suitable for applications where basic or reinforced isolation is required. Different drive strengths enable a simple driver platform to be used for applications demanding power transistors with different power ratings. Specifically, the UCC5390 device offers a 10-A minimum drive current which can help remove the external current buffer used to drive high power transistors.
