(please note that protection operates when the potential of 3 .0 v or more remains in the terminal prtc when the power supply starts, and the standby is relea sed. it is likely to protect when the power supply is started up in the slew rate of 1ms or less, and please start up the power supply in the slew rate of 1ms or more.)when the terminal prtc is 1.0v ( t yp.) or less, protection is released. please delete c o f the terminal prtc and short - circuited with gnd when the overcurrent function unused. fig ure 20 . ocp tim ing chart prtc prtout (output) ch3(traking)output ch4(f ocus )output > 3 .0 v h mute d r i v e c u r r e n t 4 7 0 m a ( t y p . ) t h r e s h o l d v o l t a g e = 3 . 0 v ( t y p . ) c u r r e n t o f c a p a c i t o r d i s c h a r g e v o l t a g e o f c a p a c i t o r d r i v e r a c t i v e m u t e a c t i v e a c t i v e p r o t e c t c i r c u i t p r t o u t p r t c c h a r g e 0 v ( t y p . ) o c p m u t e o f f o n o f f 1 . 0 v ( t y p . )
