Figure 32. ONOFF Serial Resistor Connection
If the application allows ON/OFF pin to be biased by
voltage and the power supply is not connected to Vcc pin at
the same time, then it is recommended to limit ON/OFF
current by resistor with value 10 kW to protect the NCP3066
device. This situation is mentioned in Figure 32, ON/OFF
Serial Resistor Connection.
This resistor shifts the ON/OFF threshold by about
200 mV to higher value, but the TTL logic compatibility is
kept in full range of input voltage and operating temperature
range.
