6. Muting functions
a) V
C
-drop muting
When the voltage at V
C
terminal (pin 27) drops to a value lower than 0.7V (Typ.), the outputs of all the channels are
turned off. Set the V
C
terminal voltage to larger than 1.0V.
b) V
CC
-drop muting
When the voltages at DV
CC
terminal (pin 54) and V
CC
terminal (pin 51) drop to lower than 3.8V (Typ.), the outputs of
all the channels are turned off.
7. Thermal-shutdown
A thermal-shutdown circuit (over-temperature protection circuit) is built in to prevent the IC from thermal breakdown.
Use the IC under the thermal loss allowed to the package. In case the IC is left running over the allowable loss, the
junction temperature rises, and the thermal-shutdown circuit works at the junction temperature of 175
°
C (Typ.) (the
outputs of all the channels are turned off). When the junction temperature drops to 150
°
C (Typ.), the IC start operating
again.
