CONTROL AND PROTECTION SIGNALS

1) Functions of control and protection signals

“POWER” signal: Turn the low voltage power (D+5, A+14, A+7, F+12, S+13) ON/OFF and the high voltage

power (Vs, Vd) OFF.

“POSAVE” signal: Turn the high voltage power (Vs, Vd) ON/OFF.

“LVP” signal:

Shut down the output voltage other than Stand-by power (M+5).

This signal is disable for about a second after turning the high voltage power ON.
