The recessive BUS level is generated from the integrated 30 k Ω pull-up resistor in series with an active diode. This diode pre-
vents the reverse current of VBUS during differential voltage between VSUP and BUS (V BUS > V SUP ).
No additional termination resistor is necessary to use the ATA6823C in LIN slave nodes. If this IC is used for LIN master nodes,
it is necessary that the BUS pin be terminated via an external 1 k Ω resistor in series with a diode to VBAT.

TXD Dominant Time-out Function
The TXD input has an internal pull-down resistor. An internal timer prevents the bus line from being driven permanently in
dominant state. If TXD is forced low longer than t dom > 18.4ms, the pin LIN will be switched off to recessive mode. To reset this
mode switch TXD to high (> 10μs) before switching LIN to dominant again.
Control Inputs EN1, EN2, DIR, PWM
Pins EN1, EN2
Any of the enable pins may be used to activate the IC with a HIGH. EN1 is a low level input, EN2 can withstand a voltage up to
40V. Internal pull-down resistors are included.
Pin DIR
Logical input to control the direction of the external motor to be controlled by the IC. An internal pull-down resistor is included.
Pin PWM
Logical input for PWM information delivered by external microcontroller. Duty cycle and frequency at this pin are passed through
to the H-bridge. An internal pull-down resistor is included.

At least one valid trigger has been accepted (SYNC = 1)
V VBAT is inside the specified range (UV = 0 and nOV = 1)
The charge pump has reached its minimum voltage (CPOK = 1) and
The device is not overheated (OT2 = 0)
In case of a short circuit, the appropriate transistor is switched off after a debounce time of about 10μs. In order to avoid cross
current through the bridge, a cross conduction timer is implemented. Its time constant is programmable by means of an RC
combination.
