The BTS is a fully integrated high current half bridge for motor drive applications. It is part of the NovalithICTM family containing one p-channel high-side MOSFET and one n-channel low-side MOSFET with an integrated driver ICIC BTS 7960 in one package. Due to the p-channel high side switch, the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation, and protection against overtemperature, overvoltage, Undervoltage, overcurrent, and short circuit. The BTS 7960 provides a cost-optimized solution for protected high current PWM motor drives with very low board space consumption.
The ATMEGA328P-PU is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega328P-PU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU),allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
The ATmega328P-PU AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.
