Automobile-qualified High-reliability Isolated Dual-channel Gate Drivers without DT Pins

The NSi6622-Q1 is a series of highly reliable isolated dual-channel gate driver ICs, which can be designed to drive power transistors with switching frequency up to 2MHz. Each output can source and sink up to 4A/6A with fast propagation delay of 25ns and the maximum delay matching of 5ns. The NSi6622Q1 provides 5700Vrms isolation in SOIC16 (300mil) and SOIC14 (300mil) wide-body packages. The minimum common mode transient immunity (CMTI) of 100kV/us improves system robustness. The maximum supply voltage of the driver is 28V, and the input side accepts supply voltages from 2.7V to 5V. All supply voltage pins support undervoltage lockout (UVLO). With all these outstanding features, NSI66x2 is suitable for switching power supply systems which require high reliability, high power density and high efficiency.
