6.3.2 Enable

The device has an enable (EN) pin. The outputs will be active only if the EN pin voltage is above the threshold voltage. Outputs will be held low if EN pin is left floating or pulled-down to ground. An internal 80-kΩ resistor pulls the EN pin to VSS. Thus, leaving the EN pin floating disables the device. Externally pulling EN pin to ground shall also disable the device. If the EN pin is not used, then it is recommended to tie it to VDD pin. If a pull-up resistor needs to be used then a strong pull-up resistor is recommended. For 12V supply voltage, a 10kΩ pull-up is suggested. In noise prone application, a small filter capacitor, 1nF to 10nF, should be connected from the EN pin to VSS pin as close to the device as possible. An analog or a digital controller output pin could be connected to EN pin to enable or disable the device. Built-in hysteresis helps prevent any nuisance tripping or chattering of the outputs.
