Second-generation High-performance Isolated Dual-channel Gate Driver
NSI6602V is the second-generation high-reliability isolated dual-channel gate driver IC, which enhances anti-interference capability and drive capability, reduces power consumption, and improves the withstand voltage of the input side. It can drive power transistors with switching frequencies up to 2MHz. Each channel output can provide a maximum source/sink current capability of 6A/8A with a fast 25ns propagation delay and a maximum delay match of 5ns. 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 3V to 18V. All supply voltage pins support undervoltage lockout (UVLO). In addition, multiple undervoltage points are available. The minimum undervoltage point supports 4V and can be used to drive GaN power devices. Multiple packages are available. The minimum package is the 4*4mm LGA package, which can be used in applications with high power density requirements. According to UL1577, the NSI6602V provides 2500Vrms isolation with the 5*5mm LGA13 package, 3000Vrms isolation with the SOP16 narrow-body package, and 5700Vrms isolation with SOW16 and SOW14 wide-body packages. With all these outstanding features, NSi6602V is suitable for switching power supply systems which require high reliability, high power density and high efficiency.
