Function and Terminal Circumscription Circuitry
The abnormal state detection output terminal
• The output becomes "H" from "L" when an abnormality is detected
in the OVP or UVP terminal. Then the PWM output terminal
becomes "H" settlement, too.
• Do OFF of power supply (VCC) to remove latch of abnormal state.
• In abnormal state detection;
Output "H" level = 10.5 V typ
(The output load current: no-load, VCC = 12 V)
Output "L" level = 1.5 V typ
(The output load current: −1 mA, VCC = 12 V)
• In normal state ;
Output "L" level = 0.4 V typ
(The output load current: +10 mA, VCC = 12 V)
Over voltage protection of the control line (OVP)
• Setting terminal voltage;
GND ≤ VOVP < VREF
Under voltage protection of the control line (UVP)
• Setting terminal voltage;
GND ≤ VUVP < VOVP
