3.2 System Architecture
Only a few external components are needed to build a complete closed-loop system with
maximum flexibility. To interconnect TMCC160 with a host PC or microcontroller, the following
interfaces are available: UART(RS232, RS485), CAN, SPI. An analog input supports simple
standalone applications.
To avoid power supply overshoots during deceleration/ energy feedback from
the motor, TMCC160 provides a brake chopper output which can be connected
to a low side N-channel MOSFET. The brake chopper duty cycle will be
automatically controlled depending on the supply voltage.
TMCL programs can be stored in an external EEPROM. Programs can be
automatically executed after power up or triggered from the host system.
