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 (
θ
JA
), and
the Ambient Temperature (T
). The LM3543 in the 16-pin SOIC package has a T
of 150C and a
θ
at any temperature is P
MAX
= (T
JMAX
T
A
)/
θ
JA
. 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.
