Note: There are no limitations on the magnitude relationships between the VB, VS and VDD supply voltages.
1. Stipulates the total leakage current for VB = VS = VDD when the IC is in standby mode.
2. Stipulates the operating range voltages (for guaranteed functionality) when a single power supply with VB = VS = VDD is used for the DC motor system.
3. Stipulates the operating range voltages (for guaranteed functionality) for the DC motor system VS pin, i.e., the motor power supply. The drive
current will be a constant current when VB = VS = 2.0 V or higher.
4. Stipulates the output saturation voltage when either the DC motor driver VB = VS = VDD = 1.8 V and the output current is 600 mA or when VB = VS
= VDD = 3.0 V and the output current is 1000 mA.
5. Stipulates the current emitted or accepted by the OUT3P and OUT3N pins. These are constant currents as long as VB = VS = 2.0 V or higher.
6. Stipulates the maximum total current drain for the VB and VS pins for the forward, reverse, or brake operations when drive between the DC motor
system OUT1 and OUT2 outputs is used.
7. Stipulates the maximum total current drain for the VB and VS pins for the DC motor driver drive mode standby state.
8. Stipulates the maximum total current drain for the VB and VS pins for the DC motor driver single-sided drive mode, i.e. when a single output from
the OUT1, OUT2, OUT3P and OUT3N pins is used.
9. Stipulates the operating voltage range (for guaranteed functionality) for the VREF circuit system.
10.Stipulates the input voltage range for the Vcont pin. When a constant-voltage circuit is formed by adding an external transistor, the voltage is held
constant by sensing the VCC pin.
11.Stipulates the reference voltage generated at the VREF pin.
12.Stipulates the ratio of the constant VCC pin voltage value to the VCONT pin input voltage.
13.Stipulates the minimum output voltage for the VCC pin constant voltage output. The voltage will only fall to this value, even when the VCONT pin is
set to 0 V.
14.Stipulates the VCC pin stabilized output voltage when the VREF and VCONT pins are connected directly.
15.Stipulates the change in the value of the VCC voltage when VCC is set for constant voltage output and the VB voltage varies from 2 V to 7.5 V.
16.Stipulates the change in the value of the VCC voltage when VCC is set for constant voltage output and the load current varies from 50 mA to 500
mA.
17.Stipulates the VCONT pin input current in the range 0 V ≤ VCONT ≤ VB – 0.3 V. The value of the VCC output constant voltage can be varied by
inputting the CPU D/A output.
18.Stipulates the VB system maximum current drain in all modes when the VCC output has no load.
19.Stipulates the operating voltage range (for guaranteed functionality) for the VDD pin. The VDD pin is connected either to the CPU power supply or VB.
20.Stipulates the input current and allowable leakage current for the control input pins: MD0, MD1, MD2, IN1 and IN2.
21.Stipulates the high and low input voltages for the control input pins: MD0, MD1, MD2, IN1 and IN2. (When input pins are open, they appear to be
high-level inputs.)
22.Stipulates the VDD pin current drain when all the for the control input pins (MD0, MD1, MD2, IN1 and IN2) are at the ground level.
23.When the temperature exceeds the stipulated temperature, output current limitation is applied, thus protecting the IC. The stipulated temperature is
a design target value and is not tested prior to shipment.
24.Stipulates the lower side output saturation voltage in the OUT1 and OUT2 braking modes (when IO = 600 mA).
25.Stipulates the OUT1 and OUT2 spark killer diode forward voltage (when IF = 600 mA).
26.Stipulates the minimum value of the IB pin sink current.
