Fully protected triple half bridge driver designed in SOI technology that allows especially the control of motors by a microcontroller in automotive and industrial applications. Each of the three high-side and three low-side drivers, internally connected to form three half-bridges, can drive currents up to 1.0A. Its high PWM frequency capability can smoothly control two DC motors or a BLDC motor. SOI technology allows junction temperatures of up to 200°C and enables new cost effective board design possibilities to achieve complex mechatronic solutions.
The development board contains an triple half bridge driver (ATA6832), ATmega88 microcontroller, and ATA6625 LIN SBC as a voltage regulator. Only high-temperature components populate this board. The board also includes a BLDC motor control kit with BLDC motor and a power supply cable with banana plugs. The BLDC motor control is fully integrated from the signal generation to the full BLDC motor...
Application board that allows loads to be easily adapted via its row connector pins. Design software controls its SPI interface via the PC parallel port. The board contains everything needed to start operation, including a link cable to PC 25-lead 1:1, application note and datasheet.
The development kit contains a main board with an H-bridge gate driver (ATA6823), external FETs, and DC motor. The controller board is populated with an ATmega88 microcontroller and LCD display.
Intention of the kit is demonstrating the features of the ATA6843/44 System Basis Chip BLDC Gate Driver. Motor position feedback operates with Back-Electromotive-Force (Back-EMF). Motor control microcontroller is ATmega32M1. For monitoring and evaluating purposes is an USB interface on board.
