Function and Terminal Circumscription Circuitry

P.OUT

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 (V

CC) 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)
