Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
The maximum allowable power dissipation is a function of the Maximum Junction Temperature (T
JMAX), Junction to Ambient Thermal Resistance (θJA),
and the Ambient Temperature (T
A). The LM3543 in the 16-pin SOIC package has a TJMAX of 150°C and a θJA of 130°C/W. The maximum allowable power
dissipation at any temperature is P
MAX = (TJMAX TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the
part will go into thermal shutdown.
Note 3:
The Human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin.
Note 4:
Thermal Shutdown will protect the device from permanent damage.
