(Note 4)
Note 1: The required bootstrap capacitance value varies according to the motor drive conditions. The capacitor is
biased by VCC and must be sufficiently derated for it.
Note 2: The following formula shows the detection current: IO = VR ÷ RIS (For VR = 0.5 V)
Do not exceed a detection current of 1A when using this product.
(Please go from the outside in the over current protection.)
Note 3: When using this product, some adjustment is required in accordance with the use environment. When
mounting, place as close to the base of this product leads as possible to improve the ripple and noise
elimination.
Note 4: The DIAG pin is open drain. Note that when the DIAG pin is connected to a power supply with a voltage
higher than or equal to the VCC, a protection circuit is triggered so that the current flows continuously. If not
using the DIAG pin, connect to the GND.
Handling precautions
(1)
Please control the input signal in the state to which the V CC voltage is steady. Both of the order of
the VBB power supply and the V CC power supply are not cared about either.
Note that if the power supply is switched off as described above, this product may be destroyed if the
current regeneration route to the VBB power supply is blocked when the VBB line is disconnected by
a relay or similar while the motor is still running.
(2)
The excess voltage such as the voltage serge which exceed the maximum rating is added, for example,
may destroy the circuit. Accordingly, be careful of handling this product or of surge voltage in its
application environment.
