(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 ÷ R1 (For VR = 0.5 V)
Do not exceed a detection current of 3 A when using this product.
(Please go from the outside in the over current protection.)
Note 3: When using this product, 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. If not using the DIAG pin, connect to the GND.
Handling precautions
(1)
Please control the input signal in the state to which the VCC voltage is steady. Both of the order of
the VBB power supply and the VCC 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 RS pin connecting the current detection resistor is connected to a comparator in the IC and also
functions as a sensor pin for detecting over current. As a result, over voltage caused by a surge
voltage, for example, may destroy the circuit. Accordingly, be careful of handling the IC or of surge
voltage in its application environment.
