The application board offers the possibility of an external H-bridge connection (see
2-6).
The external H-bridge can be supplied by the 4-mm banana plugs PBAT_MOTOR and
PGND_MOTOR.
The gate driver and sense pins are available via header pin connector X3 (see

Figure 2-7.
According to LIN specification 2.0, resistor R4 is not necessary when using the Atmel
ATA6823 as slave. This is the default at delivery.
To change the Atmel ATA6823 LIN from slave mode to master mode, complying with LIN
specification 2.0, a 1kΩ resistor has to be inserted in place of R4, and reverse battery protec-
tion diode has to be inserted in place of D3.
6). To change between the on-board H-bridge and the external H-bridge, jumpers JH2 to
