NSI6622
High Reliability Isolated Dual-Channel
Gate Driver
Datasheet (EN) 1.3
Product Overview
Safety Regulatory Approvals
NSI6622 is a family of high reliability isolated dual-
channel 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.
UL recognition:
SOW16/SOW14: 5700Vrms for 1 minute per UL1577
SOP16: 3000Vrms for 1 minute per UL1577
LGA13: 2500Vrms for 1 minute per UL1577
The NSI6622 provides 2500Vrms isolation per UL1577 in
5*5mm LGA13 package, 3000Vrms isolation in SOP16
package, and 5700Vrms isolation in SOW16 or SOW14
package. System robustness is supported by 150kV/μs
typical common-mode transient immunity (CMTI).
DIN VDE V 0884-11:2017-01
CSA component notice 5A
CQC certification per GB4943.1-2011
The driver operates with a maximum supply voltage of
25V, while the input-side accepts from 2.7V to 5.5V
supply voltage. Under voltage lock-out (UVLO)
protection is supported by all the power supply voltage
pins.
