Application Information
1. MUTE Function
MUTE circuit turns BTL output ON/OFF.
When MUTE terminal (pin42, pin43) is OPEN, or terminal voltage is
lower than 1V, BTL is disable.
When MUTE terminal (pin42, pin43) is voltage is higher than 1.5V,
BTL output operates normally.
Feature Table.
MUTE circuit voltage
MUTE status
Above 1.5V
Below 1V or Open
2. TSD Function
TSD circuit intercepts all IC output to protect the IC against high
temperatures.
When chip temperature rises above 165
°
C, BTL and spindle output is
disable.
When chip temperature falls below 140
°
C, BTL and spindle output
operates normally.
TSD has hysteresis of 25
°
C.
3. TSD Monitor Function
TSD monitor circuit displays TSD status.
When TSD is ON, pin18 is HIGH.
When TSD is OFF, pin18 is LOW.
Since output pin(PIN18) is open-collector, pull-up resistance should be
attached outside.
