When designing the complete system it has to be considered, that in this case (only in pre-nor-

mal mode) the pin TXD of the ATA6620N works as an output.

4.3

Pre-normal Mode

At system power-up the device automatically switches to Pre-normal mode. The voltage regula-

tor is switched on (V_CC= 5V/50 mA) (see Figure 4-7 on page 11) after typically t_VCC> 300 µs.

The NRES output switches to low for t_res= 10 ms and sends a reset to the microcontroller. LIN

communication is switched off, and the undervoltage detection is active.

A power-down of V_Batt(V_S< 4.15V) during Silent or Sleep mode switches into Pre-normal mode

after powering up the IC. During this mode the TXD pin is an output.
