In case IC chip temperature rise to 175 ℃(typ.), thermal-shut-down circuit operates and output current muted. Next time IC chip temperature falls below 150 ℃(typ.), the driver blocks start. (2) In case stand-by-pin voltage under 0.5V or opened, quiescent current is muted. stand-by- pin voltage should be over 2.0V for normal application. (3) Bias-pin (pin 27) should be pulled up more than 1.2V . In case bias-pin voltage is pulled down under 0.9V (typ.), output current is muted. (4) Insert the by-pass capacitor between Vcc-pin and GND-pin of IC as possible as near (approximatelv 0.1μF). (5) Heat dissipation fins are attached to the GND on the inside of the package. Make sure to connect these to the external GND. < Supplement > Current-feedback driver Trans conductance (output current/input voltage) is show as follows.
