3) Destruction mode for the AN7198Z, AN7199Z
The AN7198Z, AN7199Z are the power ICs with high breakdown withstanding voltage but it has been
found that the destruction occurs under special conditions.
(1) GND-open short-circuit to GND
Short-circuit of the output terminal to the GND terminal of power supply when GND terminal of the
IC is open, or short-circuit to GND when the GND terminal of the IC is over 0.7 V higher than the short-
circuited output terminal.
At that time, if V
CC
=
more than 16 V and a voltage is also applied to STB terminal, then the destruction
occurs.
(2) Short-circuit to V
CC
of the plus and minus side output terminals at the same time
If short-circuit to V
CC
fault occurs on both the plus and minus side output terminals at the same time
with a short-circuit resistor which does not actuate the protection circuit. The power GND terminal
current may exceed 10 A and the wire melts down since the current capacity of Au wire is exceeded.
(3) V
CC
GND reverse connection
Parasitic device is created everywhere and the circuit destruction takes place.
