The controllers feature complementary inputs, open-drain FAULT and Ready outputs, active Miller clamp, precise UVLOs, DESAT protection, soft shutdown on DESAT, and separate high and low controller outputs (OUTH and OUTL) for system design convenience. The NCx5700x supports 5V and 3.3V input-side signals and a wide bias voltage range on the controller side, including negative voltage capability. They offer galvanic isolation of >5kVRMS (UL1577 rating) and capabilities of >1200VIORM (working voltage). The NCx5700x series is available in the wide-body SOIC-16 package with a guaranteed 8mm creepage distance between input and output to meet reinforced safety isolation requirements.
The NCx57200 is a high-voltage gate driver with a non-isolated low-side (LS) gate driver and a galvanically isolated high-side (HS) or low-side (LS) gate driver. The device can directly drive two IGBTs in a half-bridge configuration. The isolated high-side driver can be powered by an isolated power supply or bootstrap-driven from the low-side power supply. Galvanic isolation of the high-side gate driver ensures reliable switching in high-power applications for IGBTs operating up to 800V at high dv/dt. Optimized output stages reduce IGBT losses. Features include two independent inputs with dead time and latching, precise asymmetric UVLOs, and short, matched propagation delays. The NCx57200 operates with its VDD/VBS up to 20V.
ON Semiconductor's galvanically isolated high-current gate drivers eliminate the need for a protection circuit at the half-bridge node and offer PCB design flexibility.
