Operation notes
(1) Thermal-shut-down circuit built in. 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-bypin 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.
