The Texas Instruments UCC27442-Q1 can handle –5V on its INx inputs, which improves robustness in systems with moderate ground bouncing. The inputs can be connected to most controller outputs for maximum control flexibility. An independent enable signal allows the power stage to be controlled independently of the main control logic. In the event of a system fault, the gate driver can quickly shut off by pulling the enable low. Many high-frequency switching power supplies exhibit noise at the gate of the power device, which can get injected into the output pin on the gate driver and cause the driver to malfunction. The device’s transient reverse current and reverse voltage capability allow it to tolerate noise on the gate of the power device or pulse transformer and avoid driver malfunction.
