9 / 32 page 9 IR1110 ADVANCE INFORMATION www.irf.com Operating Mode/Fault Output Matrix Chart Fault Fault output Mode condition indicator Description External setting Non- SCR output firing active. LNLSLED = low, LNLSSL = VDD multiplexed 1PHLED = high 1PHEN = VDD or VSS Normal 1PHSEL = VDD Multiplexed SCR output firing active. LNLSLED = low, LNLSSL = VSS 1PHLED = high 1PHEN =VDD or VSS 1PHSEL = VDD Non- SCR output firing disabled for period of loss. LNLSSL = VDD 3-phase multiplexed LNLSLED = high, 1PHLED = high 1PHEN =VDD or VSS 1PHSEL = VDD loss Multiplexed SCR output firing disabled for period of loss. LNLSSL = VSS LNLSLED = high, 1PHLED = high (Note 1) 1PHEN =VDD or VSS 1PHSEL = VDD Non- SCR output firing active. LNLSSL = VDD 1-phase multiplexed LNLSLED = low, 1PHLED = toggles low for 1PHEN = VSS 3-phase loss 2msec once or twice per line cycle 1PHSEL = VDD Input without Multiplexed SCR output firing active.LNLSLED toggles LNLSSL = VSS operation shutdown high while 1PHLED toggles low for 2msec 1PHEN = VSS once or twice per line cycle. (Note 2) 1PHSEL = VDD Non- SCR output firing disabled for period of loss. LNLSSL = VDD 1-phase multiplexed LNLSLED = low, 1PHLED = toggles low 1PHEN = VDD loss for 2msec once or twice per line cycle 1PHSEL = VDD with Multiplexed SCR output firing disabled for period of loss. LNLSSL = VSS shutdown LNLSLED toggles high while 1PHLED toggles 1PHEN = VDD low for 2msec once or twice per line cycle. 1PHSEL = VDD (Note 2) High/Low LNLED If line voltage exceeds the specified level on LNSET=desired voltage, AC line LNSET voltage, then LNLED = low. Otherwise 1PHEN =VDD or VSS LNLED = high 1PHSEL = VDD Non- SCR output firing disabled for period of loss. LNLSSL = VDD multiplexed LNLSLED = high, 1PHLED = high 1PHEN =VDD or VSS 1-phase 1PHSEL = VSS loss Multiplexed SCR output firing disabled for period of loss. LNLSSL = VSS LNLSLED = high, 1PHLED = high 1PHEN =VDD or VSS 1PHSEL = VSS 1-phase Non- SCR output firing active. LNLSLED = low. LNLSSL = VDD input multiplexed 1PHLED toggles low for 2msec once or twice 1PHEN =VDD or VSS operation Normal per line cycle 1PHSEL = VSS Multiplexed SCR output firing active. LNLSLED toggles LNLSSL = VSS high while 1PHLED toggles low for 2msec 1PHEN =VDD or VSS once or twice per line cycle. (N ote 2) 1PHSEL = VSS High/Low LNLED If line voltage exceeds the specified level on LNSET=desired voltage, AC line LNSET voltage, then LNLED = low. Otherwise 1PHSEL= VSS LNLED = high 1PHEN =VDD or VSS Note 1) LNLSLED may toggle high once for 2msec after event of phase loss. Note 2) 1PHLED and LNLSLED are completely synchronized and complementary. uld ctical e is |
