8.3.5 Enable Input Pin (EN)

The enable input pin controls the operation mode of the TPIC1021 (Normal or Low Power Mode). When enable is high, the TPIC1021 is in normal mode allowing a transmission path from TXD to LIN and from LIN to RXD. When the enable input is low, the device is put into low power (sleep) mode and there are no transmission paths. The device can enter normal operating mode only after being woken up. The enable pin has an internal pull-down resistor to ensure the device remains in low power mode even if the enable pin floats.
