BLOCK DIAGRAM
PIN FUNCTION
TA8428K (S), TA8428F/FG has 2 build−in protective functions which work independently.
These circuit operations are as follows.
Thermal shutdown (TSD)
If junction temperature of TA8428K (S), TA8428F/FG 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”)
