10. Current Monitoring
11. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Reference point pin 13, unless otherwise specified.

The U2102B’s current monitoring circuit represents a double electronic fuse. The circuit mea-
sures the current flowing through the power switch by means of the voltage drop across the
shunt resistor R
due to a high load current (e.g., short circuit), the switch-off latch is set and the switching output
pin 11 closes immediately. Pin 11 can be connected to the gate via a resistor or network,
depending on load conditions, thus allowing the switch-off behavior to be adapted to the respec-
tive requirements. The short-circuit current is reduced to a problem-free value by this procedure.
There is a second threshold at 100 mV. Without exceeding the switch-off threshold of 500 mV,
the output stage is also disabled in the voltage at pin 11 exceeds the value of 100 mV for
condition due to the line and leakage inductances, the output stage is not switched off immedi-
ately. It is disabled during the next half-wave.
