NSi6602 High Reliability Isolated Dual-Channel Gate Driver Datasheet (EN) 1.7 Product Overview NSi6602 is a family of high reliability isolated dualchannel gate driver ICs which can be designed to drive power transistor up to 2MHz switching frequency. Each output could source 4A and sink 6A peak current with fast 25ns propagation delay and 5ns maximum delay matching. The NSi6602 provides 2500Vrms isolation per UL1577 in 5-mm x 5-mm LGA13 package, 3000Vrms isolation in SOP16 (150mil) package, and 5700Vrms isolation in SOP16 (300mil) or SOP14 (300mil) package. System robustness is supported by 150kV/us typical commonmode transient immunity (CMTI). The driver operates with a maximum supply voltage of 25V, while the input-side accepts from 2.7V to 5V supply voltage. Under voltage lock-out (UVLO) protection is supported by all the power supply voltage pins.

Function Description 7.1. Overview NSi6602 is a high reliability dual channel isolated gate driver which could be designed in variety switching power and motor drive topologies. NSi6602 has some useful protections, such as under voltage lock-out (UVLO) for both input and output supply, a disable pin, dead-time control, default low output as input is floating. The functional circuit block diagram is shown as below: VDDI VDDA UVLO UVLO DIS MOD Isolation barrier INA DEMOD Control Logic INB Driver Logic OUTA GNDA Functional Isolation VDDB UVLO DT DeadTime Control MOD DEMOD Driver Logic GNDI OUTB GNDB Figure 7.1 Functional Block Diagram 7.2. Under Voltage Lock Out (UVLO) The NSi6602 has an internal under voltage lock out (UVLO) protection on both input and output supply circuit blocks. The driver output is held low by an active clamp circuit when the supply voltage of VDDI or VDDA/VDDB is lower than VVDD_ON at power-up status or lower than VVDD_OFF after power-up, regardless of the status of the input pins. The VDDI and VDDA/B ULVO protections have hysteresis (VVDD_HYS) to prevent chatter noise from VDD supply and allow small drops in supply power which are usually happened in startup.
