... BLDC Motor Control Kit with ATA6833/ATA6834 1. Introduction This document provides details on using the ATA6834-DK for BLDC motor control applications. The BLDC Motor Control Kit consists of two boards: • Basic board with a BLDC Gate Driver SBC (System Basis Chip) ATA6833/ATA6834 and external MOSFETs • ...

... It can be deactivated via a jumper, which is useful for debugging. The LIN transceiver enables the communication with the auto- motive environment. The ATA6833/ATA6834 works with a two-stage charge pump to run down to very low battery supply voltages. The charge pump facilitates low-drop reverse-voltage protection with an N-channel MOSFET. ...

... Value (CBA) Commutations are updated at each step to create a rotating magnetic field as shown in 3-3. This method takes full advantage of the ATA6833/ATA6834 in combination with the ATmega32M1 as commutations can be transmitted at each step, while PWM allow magnetic field magnitude tuning independently to act on motor torque and speed. ...

... Watchdog. 4.1 Cooling Area Design The driver IC ATA6833/ATA6834 is housed in a QFN package. QFN package is suitable for power package due to the exposed die pad; however, ensure the heat slug is completely sol- dered to the PCB. To reduce thermal resistance, vias down to the soldering layer are necessary. A sufficient ground plane has to be placed on the soldering layer to get rid of the thermal energy ...

... BLDC Motor Control Kit with ATA6833/ATA6834 The charge pump shuffle capacitors should be connected in a short loop. The VG capacitor should be connected in a short loop to the ground reference point. The reservoir capacitor at CPOUT can be connected to PBAT to reduce maximum voltage at the capacitor. Therefore, electrical voltage rating up to 25V is sufficient. ...

... If the junction temperature is increased by further 25K, the outputs, voltage regulator and LIN transceiver are switched off. Maximum junction temperature of the ATA6833 is 150°C and of the ATA6834 is 200°C. The maximum ambient temperature depends on the power dis- sipation of the device; a better thermal contact allows a higher ambient temperature. ...

If this is not done, the display remains dark and the VCC current demand is only the demand of the Hall sensors. The microcontroller and BLDC operation can also run without J1. In this case, inter- action with the panel is possible ...

... At CPout, the charge pump voltage is measurable. The charge pump voltage level U is approximately 15V higher than U • If the ATA6833/ATA6834 is in standby mode, the high voltage output switch pin VBATSW is off and LED On/Sleep is off. There are two possibilities to wake up the Basis board: press S1 “ ...
