The UCC57102Z-Q1 is a single channel, high-performance low-side IGBT/SiC gate driver for high power automotive applications such as PTC heaters, traction inverter active discharge circuit, and other auxiliary subsystems. It offers protection features including Under-voltage-lock-out (UVLO), Desaturation protection (DESAT), FAULT report, and thermal shutdown protection. The UCC57102Z-Q1 has a typical peak drive strength of 3A and it can handle –5V on its inputs, which improves robustness in systems with moderate ground bouncing. The inputs are independent of supply voltage and can be connected to most controller outputs for maximum control flexibility. The wide voltage range of the bias supply provided in the UCC57102Z-Q1 accommodates bipolar voltage. An accurate 5V output LDO is also available with the UCC57102Z-Q1 .
