... Application Board ® The Atmel ATA6823 application board allows the running motor. The supply voltage 18V, maximum power of the DC motor is limited by the external H-bridge MOSFETs. No microcontroller is implemented on-board possible to con- trol the motor either via an external microcontroller (with or without LIN bus), or directly (using the DIR and PWM pins) ...

... EN2 2.2 Getting Started To run the ATA6823 application board 18V supply voltage between VBAT and GND is necessary. To check the board at start up, following voltages are measurable at 12.5V VBAT voltage. After the power supply is switched on, a level measurable at VINT and the header pin VCC ...

... 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 ...

... Optionally, the watchdog frequency can be changed via resistor R5, by setting jumper RWD to position 1-2. Either SMD (R5A) or wired (R5B) resistors may be used. 4961B–AUTO–02/ the shunt can be connected to the AD converter of the microcontroller.

... Enable After power-on, the Atmel ATA6823 is in run mode. A falling edge at pin EN1 switches the device to standby mode. Switching Atmel ATA6823 back to run mode is possible either by switching LIN to GND or by switching EN2 to VBAT ...

... If overtemperature of higher than 150°C is detected, the pin DG3 is set to high. The occur- rence of overtemperature will be latched until the next watchdog pulse. If monitoring signals DG2 or DG3 indicate failure, the ATA6823 will switch off the motor bridge. 3.5 Motor Bridge OFF When the PWM signal is set to low, both high-side MOSFETs are switched on to slow the motor down ...
