GU SOP 1 Form A Short Circuit Protection (AQY210KS)
ASCTB27E 201201-T
What is short circuit protection latch type?
When the load current reaches a certain
fixed value, the short circuit protection
function activates to completely cut off
the load current and keep the PhotoMOS
turned off.
The short circuit protection inside the
PhotoMOS instantaneously
(typ. 50 µs) and completely cuts of the
load current.
This protects any circuits that follow the
PhotoMOS from excess current.
There is almost no heating of the
PhotoMOS, which prevents it from
becoming damaged. To restore the
function of the PhotoMOS turn off the
input current and then turn it back on.
In order to operate the short circuit
protection function, ensure that the input
current is at least IF = 5 mA.

Normal PhotoMOS operation
Occurrence of
short circuit current
Abnormal current
The short circuit current
detection device latches
when the PhotoMOS is off.
The PhotoMOS operates normally
when the input current is reset.
If the output section shorts even after
the input current is reset, it will latch
when the short circuit current is detected
again and the PhotoMOS turns off.
