NIRSP31  
Triple-Channel Digital Isolators With  
Integrated DC to DC Converter  
Datasheet (EN) 1.2  
Applications  
Product Overview  
Industrial Battery Management System  
The NIRSP31 series devices are triple-channel digital  
isolators with integrated isolated DC-DC converter. The  
isolated DC-DC converter provides stable output voltage  
and up to 400mW output power by closed-loop control  
and transformer on chip. The feedback PWM signal is  
sent to primary side by a digital isolator based on  
Novosense capacity isolation technology. The high  
integrated solution can help simplify system design, save  
PCB area and improve reliability. The NIRSP31 series  
devices support 3kVrms insulation 1min withstand  
voltage. The data rate of the NIRSP31 series devices are  
up to 20Mbps, and the common-mode transient  
immunity (CMTI) is up to ±50kV/us.  
Industrial automation system  
Isolated RS232, RS485, CAN  
General-purpose multichannel isolation
