Power Supply Sequence (recommended)
Note 1: If the VDD drops to the level of the VDDR or below while the specified voltage is input to the VM pin, the IC is
internally reset.
This is a protective measure against malfunction. Likewise, if the VM drops to the level of the VMR or below
while regulation voltage is input to the VDD, the IC is internally reset as a protective measure against
malfunction.
To avoid malfunction, when turning on VM or VDD, to input the STANDBY signal at the above timing is
recommended.
It takes time for the output control charge pump circuit to stabilize. Wait up to tONG time after power on
before driving the motors.
Note 2: When the VM value is between 8 to 11 V, the internal reset is released, thus output may be on. In such a
case, the charge pump cannot drive stably because of insufficient voltage. The Standby state should be
maintained until VM reaches 13 V or more.
Note 3: Since VDD = 0 V and VM = voltage within the rating are applied, output is turned off by internal reset.
At that time, a current of several mA flows due to the Pass between VM and VDD.
When voltage increases on VDD output, make sure that specified voltage is input.
