c???? silicon touch technology inc. sp-md114-a.006.doc version a.006 page 8 z normally vb should provide enough current for output loading, thus large value of capacitor such as is suggested for the terminal vb. besides, 0.01uf~0.1uf of capacitors are also suggested between each output channel and output channel to ground. z the settling time from standby mode to output ready is about 10us. the main difference between standby1 and standby2 depends on voltage reference in the internal circuit is ready or not. in general, the rising time of constant current from the mode, standby2, to the mode, o1 & o2 (or o2 & o3) should be faster than that of the mode, standby1 . however, the supply current 2 stb i is larger than that of 1 stb i , there is the tradeoff between the rising time and the amount of supply current. z constant current operation of 11-md1 14 provides the current, which can be evaluated by the formula () () 0.2 a fg i r = . it is obviously that constant current depends on the loading resistance of the termi nal, rfg. therefore, how to reduce the effect of line resistance from the terminal, rfg, to gnd, will decide the accuracy of constant current. z the power dissipated by the ic varies widely with the suppl y voltage, the output current, and loading. it is important to ensure the application does not exceed the allowable power dissipation of the ic package. the recommended motor driver power dissipation versus temperature is depicted as follows: pdmax vs ta jesd51-7 100 200 300 400 500 600 700 800 900 1000 power dissipation(mw) 0 25 50 75 100 125 jesd51-3 870mw 486mw ambient temperature ( )
