APPLICATION METHOD FOR M52745SP
CLAMP PULSE INPUT Clamp pulse width is recommended above 15kHz, 1.0sec above 30kHz, 0.5sec above 64kHz, 0.3sec. The clamp pulse circuit in ordinary set is a long round about way, and beside high voltage, sometimes connected to external terminal, it is very easy affected by large surge. Therefore, the Fig. shown right is recommended.
NOTICE OF APPLICATION *Make the nearest distance between output pin and pull down resistor. *Recommended pedestal voltage of IC output signal is 2V.
