5 / 11 page UTC UA9392 LINEAR INTEGRATED CIRCUIT UTC UNISONIC TECHNOLOGIES CO. LTD 5 QW-R109-010,A CIRCUIT OPERATION (1) Fig. 2 shows the inputs from the digital servo IC for CH1-CH3 drivers(all drivers except the spindle).SW1 is on when the forward input signal(HIGH level, over 2.4V) is present,SW2 I on when the reverse input signal is present (Fig. 1) The constant current (I1) at this time enters the RC and generates an integral waveform based on the duty of the input waveform. The BTL is output from BUF1 and BUF2 (Fig.3). INTER- FACE F R SW1 SW2 I1 I2 24pF 100K BUF1 BUF2 OUT R OUT F Fig. 1 To maintain the HIGH level with forward (or reverse) in-put, the DC voltage generated at point A is: I1×R ≒ 2.5V (reverse : - 2.5V) 5V 0V 0V F (R) R (F) INPUT Fig. 2 This is the voltage generated relative VREF. The setting is such that a voltage differential of 5V is generated be-tween output pins. The time constant is: R×C = 2.4μsec This can be increased by inserting a capacitor between point A (pin3,11and 18) and VREF·The constant current (Iconst) given in the electrical characteristics refers to I1 and I2 in Fig.1. (2) CH4 driver (spindle driver) Pins 23 and 25 are shorted inside the IC.Bias amplitudes are the primarytype of inputs assumed. F R SW2 SW1 L L OFF OFF L H OFF ON H L ON OFF H H OFF OFF H: 2.4V Max. L: 0.5V Min. |
