8.3.5 Remote Enable

The TPSF12C1 has an enable input, EN, that allows the device to be shut down, drastically reducing power consumption during intervals when EMI mitigation is not required. The typical quiescent current consumption is 13.2 mA and 55 μA when the device is enabled and disabled, respectively. Because many designs may not use this feature, a 850-kΩ pullup resistor connects internally between VDD and EN, allowing the EN pin to be left open.

In addition, INJ is pulled low when the device is disabled to reduce the effective resistance in series with CINJ.
