1.1 Control Interfaces
The TMC6200 supports six control lines for the MOSFET drivers. High-side and low-side outputs can be individually controlled, or by an individual enable pin plus polarity pin, using internal BBM circuitry. An SPI interface or standalone configuration is supported.
1.1.1 Standalone Configuration
Standalone configuration covers the most important settings like driver current and current amplifier amplification factor and the selection of internal or external BBM operation using four pins. Additional settings like BBM time and sensitivity of short detection can be modified using pre-programming via OTP memory, e.g. via an initial programming during product testing. This way, the driver can be fully operated and all protection mechanisms are in place. The fault output signals any critical driver error. It becomes cleared by disabling / re-enabling the driver. However, no advanced debugging is possible, like individual testing of failure mechanisms or setting a more sensitive temperature threshold. Also, it is not possible to switch to 20x current amplifier amplification. Hint Standalone configuration is recommended for low-cost applications with small motors (e.g. motor current up to 10A RMS), where advanced debugging is not required or not possible. In case a sensitive overtemperature threshold must be set, or 20x current amplifier amplification is required due to high motor current, the SPI interface should be used.
1.1.2 SPI Interface
The SPI interface is a bit-serial interface synchronous to a bus clock. For every bit sent from the bus master to the bus slave another bit is sent simultaneously from the slave to the master. Communication between an SPI master and the TMC6200 slave always consists of sending one 40-bit command word and receiving one 40-bit status word. The SPI command rate typically is a few commands for initialization or for diagnostic feedback. Attention When operating in SPI mode, set drive mode (single line or individual control signals) first. For safety reasons, the driver starts up in single line mode. This setting will prevent operation if a controller operates the IC using individual control signals. Current amplifier amplification can be set within the same write access. www.trinamic.com
