SHORT-CIRCUIT PROTECTION
When a short-circuit occurs at one or more outputs to
ground or to the supply voltage, the output stages are
switched off until the short-circuit is removed and the
device is switched on again, with a delay of approximately
20 ms, after removal of the short-circuit. During this
short-circuit condition, pin 16 is continuously LOW.
When a short-circuit across the load of one or more
channels occurs the output stages are switched off during
approximately 20 ms. After that time it is checked during
approximately 50 µs to see whether the short-circuit is still
present. Due to this duty cycle of 50 µs/20 ms the average
current consumption during this short-circuit condition is
very low (approximately 40 mA).
During this short-circuit condition, pin 16 is LOW for 20 ms
and HIGH for 50 µs (see Fig.4).
The power dissipation in any short-circuit condition is very
low.

TEMPERATURE DETECTION
When the virtual junction temperature Tvj reaches 150 °C,
pin 16 will be active LOW.
OPEN COLLECTOR OUTPUT
Pin 16 is an open collector output, which allows that more
devices can be connected together (pins 16).
