Note1.
In the uper table. “On” means always On. “Off” means
compulsory Off and “On/Off” means that it can con-
trol by control terminal.
Note2.
Thermal protection circuit
A built-in thermal protection circuit (TSD:Thermal shut
down) prevents thermal damage to the IC. All outputs
except VDD (pin14) and FREG (pin2&3) are switched
off when the circuit operates, revert to the original
state when the temperature drops to a certain level.
Note3.
Overvoltage protection circuit
The overvoltage protection circuit (surge protector)
turns off all outputs without Vdd, when VB voltage
is more than about 21V. And the overvoltage protec-
tion circuit (surge protector) turns off Vdd output with
other all outputs, when VB voltage is more than about
26V. When the overvoltage protection operates on
VB>=18V condition, the stand by current increases.
Note 4.
Overcurrent protection circuit
FREG_B (pin2), ILMOUT (pin4), CDOUT (pin6),
DSPOUT (pin7), AUDIOOUT (pin10), EXITOUT (pin12),
VDDOUT (pin14) output circuits are built-in overcur-
rent protection circuit based on the respective output
current. These overcurrent protection circuits limit
the current with a curve shape of “7” in the voltage-
current graph. This prevents IC destruction due to
overcurrent.
