Enable Input Pin (EN)
Inhibit Output Pin (INH)
Wake-up Input Pin (WAKE)
ATA6662
This pin controls the Operation Mode of the interface. If EN = 1, the interface is in Normal Mode,
with the transmission path from TXD to LIN and from LIN to RXD both active. At a falling edge
on EN, while TXD is already set to high, the device is switched to Sleep Mode and no transmis-
sion is possible. In Sleep Mode, the LIN bus pin is connected to V
source. The device can transmit only after being woken up (see
(INH)”
During Sleep Mode the device is still supplied from the battery voltage. The supply current is
typically 10 µA. The pin EN provides a pull-down resistor in order to force the transceiver into
Sleep Mode in case the pin is disconnected.
This pin is used to control an external switchable voltage regulator having a wake-up input. The
inhibit pin provides an internal switch towards pin V
high-side switch is turned on and the external voltage regulator is activated. When the device is
in Sleep Mode, the inhibit switch is turned off and disables the voltage regulator.
A wake-up event on the LIN bus or at pin WAKE will switch the INH pin to the V
system power-up (V
This pin is a high-voltage input used to wake the device up from Sleep Mode. It is usually
connected to an external switch in the application to generate a local wake-up. A pull-up current
source with typically –10 µA is implemented. The voltage threshold for a wake-up signal is 3V
below the VS voltage with an output current of typically –3 µA.
If you do not need a local wake-up in your application, connect pin WAKE directly to pin VS.
