TA8428K (S), TA8428F has 2 build−in protective functions which work independently.
These circuit operations are as follows.
l Thermal shutdown (TSD)
If junction temperature of TA8428K (S), TA8428F is over the specified temperature (150°C Typ.) by excess
power dissipation or abnormal ambient temperature change, thermal Shutdown circuit turn “ON” and output 4
transistors become High impedance. (All transistors turn “OFF”)

l Short current protector (ISD)
Short current protector circuit senses all output transistor current. If output transistor current is over the
specified limiting current value (2.0~3.0 A Typ.), short current protector operates and all output transistors
periodically turn “OFF” (High Impedance Mode) in a period of approximately 80 µs.
This state is continued until the release of over current mode.

Note: Recommend to take approximately 100 ms of input dead time for reliable operations.
Note: Utmost care is necessary in the design of the output line, V
and GND line since IC may be destroyed due
CC
to short−circuit between outputs, air contamination fault, or fault by improper grounding.
Note: In case of mounted on radiators, do not use silicon rubber. (TA8428K (S))
Note: Connect and use 1 pin and 3 pin surely. (TA8428F)
