3. Start-up correction function (ISH, OUT9, OUT10)
The ISH pin input voltage is set with the decay time constant to be larger than the coil decay time constant by using
the external CR and the start-up correction occurs with respect to the coil wave.
By doing this, stable shutter operation can be carried out with respect to the power supply variations.
(Note) For the ISH pin start-up correction, check the coil current start-up wave for the VCC reduced voltage when
there is no ISH pin capacitor and choose a capacitance so that the decay time constant is lower than this wave.
However, at times such as when the power supply voltage is stable or the start-up correction function is not required,
such a start-up correction capacitor is not necessary.
4. Phase compensation capacitor (FC1, FC2)
See and check the capacitor value for FC1 and FC2 between 0.0015 to 0.033
μ
F. Choose a capacitance value which
does not cause oscillation problems for output. (In particular, when a coil with large inductance is used, it is
necessary to choose a sufficiently large capacitance.) Also, as the constant current control block within the IC is
connected to PGND, be sure to connect the ground side of the FC1 pin and FC2 pin capacitor to PGND.
5. Constant voltage control Oscillation-stopping capacitor (OUT1 to 8)
When controlling the constant voltages, it is necessary to place capacitors between the OUT pins to stop oscillation.
See and check the capacitor value between 0.01
μ
F to 0.1
μ
F. Choose a capacitance value which does not cause
oscillation problems for output. When driving at saturation, there is no need for such oscillation-stopping capacitor.
6. GND wiring and power line capacitors : (PGND, SGND, VCC, VB1, 2, VDD)
Connect PGND (2 places) and SGND near the IC, and place the capacitors as close as possible to each of the power
pins.
