Internal Constant-Voltage (5 V) Circuit
This IC includes a 5 V power supply for control circuit.
A capacitor for prevention of oscillation should be connected to S-GND associated with the pin Vreg.
No other loads should be connected to pin Vreg.
This IC has a power monitoring function and turns the output OFF when Vreg goes down to 3.0 V
(design target value) or less. With a hysteresis of 0.3 V (design target value), the output are turned ON
when Vreg again reaches 3.3 V (design target value).
4.
Charge Pump Circuit
This IC has a charge pump circuit for driving the gate for the upper power transistor in the output
circuit. A voltage of VCC + 5 V (typ.) is generated by connecting an external capacitor to this IC.
It takes about 2 ms to boost VCPA up VCC + 5 V (typ.) after the switching of the input signal from the
standby pin (while CcpA
= 0.22 F, and CcpB and CcpC are connected through 0.01 F).
The proper capacitance of the external capacitor varies depending on the VCC value. Thus, determine
the constant by referring to the following data. The value of the capacitor between CcpB and CcpC
should be such that, while the motor is being driven, the voltage on the CcpA pin will be kept constant,
typically at VCC + 5 V. (If a reduced VCC level causes the voltage on CcpA to start to fall, please adjust
this capacitance value accordingly.)
