QLMP-AD94-SS0DD Datasheet The READY circuit is a re-triggerable 195ys monostable, which is re-triggered by every down regulating action of comparator Compl. As long as regulation takes place, output READY is "HIGH" (high impedance, 100K to Vcc). Short dips of the output voltage of less than 195ys are ignored. If the output voltage falls below the nominal value for more than 195ys,output READY goes "LOW". This can be used to signal to the camera controller that the flash unit has charged fully and is ready to use. QLMP-AD94-SS0DD Price to complete; the burst length depends on the value of Cs, the Cx capacitances, and Cfinger. Increasing Cs increases the burst length, increasing Cx3 decreases burst length, and increasing Cxl and Cx2 increase burst length. Increasing Cfinger decreases the burst length. The value of the burst length is thus a variable that is dependent on these capacitances; the burst length is used to create an internal reference signal level during a calibration cycle, and to determine the presence of touch by virtue of a change in the burst length relative to the reference level.
