When the chip temperature has been 150
(Typ.), the output current is muted. And when the
chip temperature has dropped to 130
(Typ.), the driver circuit starts up.
Note in use
1. Between power supplies, attach a by-pass capacitor (approx. 0.1
μ
F) at the root of this IC.
2. In principle, do not apply voltage below sub-potential of IC to terminal. Examine in consideration of
operation margin, when each driver output falls below sub-voltage of IC (GND) due to counter-
electromotive-force of choke coil, etc.
3. Output pin is to avoid short-circuiting with PVCC, GND, and other output pins. And, be fully careful
in the direction of an integrated circuit on the substrate.
4. When use AC adapter, if apply beyond 7V to DC_IN pin, connect Z-Di with DC_IN pin. So keep
voltage of DC_IN being below 7V. To protect IC, once the voltage to be applied on the DC_IN
terminal exceeded 7.5V (Typ.), SPRT terminal can be charged.( I
