6/6
1. Thermal-shut-down circuit built-in. In case IC chip temperature rise to
175
°
C(typ.), thermal-shut-down circuit operates and output current is muted. Next
time IC chip temperature falls bellows 150
°
C(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. In case supply voltage falls below 3.5V (typ.), output current is muted. Next time
supply voltage rises to 3.7V(typ.), the driver blocks start.
4. Bias\pin (pin27) should be pulled up more than 1.2V. In case bias-pin voltage is
pulled down under 0.9V (typ.), output current is muted.
5. Insert the by-pass capacitor between Vcc-pin and GND-pin of IC as possible as
near (approximately 0.1
μ
F).
6. Heat dissipation fins are attached to the GND on the inside of the package. Make
sure to connect these to the external GND.
7. Output pin is to avoid short-circuit with Vcc, GND and other output pins.
And, be fully careful in the direction of an integrated circuit when you put an
integrated circuit.
On the substrate. An integrated circuit is damaged, and smoke may come out by
the case.
