5.Timer latch-up (T SCP )
Thermal protection circuit
Charge pump
The user can set the time at which the outputs are turned off when a short-circuit occurs by connecting a capacitor
(C SCP ) across the SCP and GND pins. The value of the capacitor (C SCP ) can be determined by the following formula :
This IC incorporates an thermal protection circuit, and the output is turned off when junction temperature Tj exceeds
180°C, and the abnormal state output (EMO pin) is turned on at the same time. The output is driven again when
temperature hysteresis falling (automatic restoration). The overheating protection circuit doesn't guarantee protection
and the destruction prevention of the set because it becomes operation by the area where ratings Tjmax=150°C of the
junction temperature were exceeded.
This IC makes “H” ST pin, and operate the charge pump circuit, and VG pin voltage step-up VM voltage to VM+REG5
voltage. Use it after the time of tONG or more passes when drives the motor. If it is not so, on-resistance cannot be
secured.
