(3) rise compensation function (ish, out9, out10) ish coil current vcc high (without ish capacitor) vcc low (without ish capacitor) rise compensation ish discharge sh closing rise compensation coil current setting the input voltage of ish pin larger than the coil time constant by means of an external cr enables application of rise compensation to the coil waveform, ensuring stable shutter operation against fluctuation of power supply. (note) in ish rise compensation, the rise waveform of coil current during vcc power reduction in the condition without ish capacitor is checked. the capacity is determined so that the time constant becomes lower than this waveform. note that the rise compensation capacitor is not necessary when the rise compensation function is not necessary, for example, when the stable supply voltage is supplied. (4) phase compensation capacitors (fc1, 2) set fc1 and 2 capacitors to the capacitance value within the range of 0.01 to 0.1 m f that does not present an oscillation problem to the output. particularly when a coil with high impedance is to be used, it is necessary to provide an allowance to the capacitance. as the constant-current control block is connected to pgnd in ic, connect the gnd side of fc1 and 2 capacitors to pgnd. (5) constant-voltage control oscillation preventive capacitors (out1 to 8) for constant-voltage control, it is necessary to insert a capacitor between out pins to prevent oscillation. set the capacitor within a range of 0.01 m f to 0.1 m f that does not present an oscillation problem to the output. this oscillation preventive capacitor is not necessary when drive is made in the saturated condition. (6) capacitors for gnd wiring and each power line (pgnd, sgnd, vcc, vb1, 1, vdd) connect pgnd (two points) and sgnd near ic and insert a capacitor directly near the power pin for each power supply. .com .com .com .com 4 .com u datasheet
