The UCC23711DWREVM is a gate driver evaluation board that features two isolated protection gate drivers. These drive two series FETs or IGBTs in a half-bridge, for analysis of drive strength, timing, DESAT protection, noise immunity, and thermal impedance. The UCC23711 is designed to both protect FETs and IGBTs from overcurrent damage and help meet functional safety requirements. This board also features two isolated power devices which supply ± DC rails for both the high-side and low-side gate driver channels. The rail voltages can be adjusted using the UCC14141 feedback resistors. For ease of alteration in low-voltage testing, a series resistor out of these integrated supplies can be removed and the power rails can instead be provided externally.
