Note 1: Perform thermal calculations for the maximum current value of the motor under normal conditions. Use the
IC at 0.6 A or less per phase.
Note 2: Under the condition of DCDC output voltage
× 0.9 V or higher (typ.)
In this case, the input current to the power supply becomes the current value (1.2 A) that is controlled by the
sense resistor.
Note 3: Under the condition of DCDC output voltage
× 0.9 V or lower (typ.)
Note 4: The output current is lower by 20% than the input current value of the DCDC converter (calculated value).
When The value of IDCOUT is 1.2 A (max), the output current will be 0.96 A (max).
Note 5: Input 5.5 V or less as VIN.
Note 6: Measured for the IC only. (Ta
= 25°C)
Note 7: Measured when mounted on the board. (Ta
= 25°C)
Ta: IC ambient temperature
Topr: IC ambient temperature when starting operation
Tj: IC chip temperature during operation Tj (max) is controlled by TSD (thermal shutdown circuit)
Note : Notes on maximum voltage
This device does not incorporate an overvoltage protection circuit. When an excessive voltage is applied to
the device, it may be destroyed. Thus, make sure that the power supply voltage is within the specification
value.
