my customer choose ISO7821DWWR in their system to achieve isolated UART communication between C2000 and STM32F107.
C2000 is controlling a 1500VDC solar inverter system.
And they need to achieve reinforced isolation between C2000 board(hot side) and STM32F107 board(cold side).
And they said that 15mm clearance and creepage is a must for them to pass the reinforced isolation certification for 1500V system.
And in the datasheet 220.127.116.11, TUV column: I don't know whether I should choose 1000VRMS or 1450VRMS.
5700 VRMS Reinforced insulation per EN 61010-1:2010 (3rd Ed) up to working voltage of 600 VRMS (DW package) and 1000 VRMS (DWW package)
5700 VRMS Reinforced insulation per EN 60950-1:2006/A11:2009/ A1:2010/A12:2011/A2:2013 up to working voltage of 800 VRMS (DW package) and 1450 VRMS (DWW package)
And if 1450VRMS, does it correspond to 1450*1.414=2050VDC?
