TMC8461-BA
Brand: Analog Devices
The TMC8461-BA is an EtherCAT Slave Controller that steps up from the TMC8460 by adding integrated 5–24 V switching regulators and 35 V-capable high-voltage I/Os, letting a single 144-ball BGA device sit directly at the field level without a separate power-supply IC. SPI/I²C master units give the ESC direct access to external ADCs and stepper motor controllers, and device-emulation or external-CPU modes cover both stand-alone and host-processor designs.

Interface Features & Applications
- Integrated 5–24 V switching regulators generate the internal 3.3 V rail from a single high-voltage supply
- 8 high-voltage I/Os rated to 35 V / 100 mA extend EtherCAT reach directly to field-level sensors and actuators
- 24 multi-function I/Os plus 4 PWM outputs and a STEP/DIR generator cover auxiliary drive and I/O duties
- SPI/I²C master units let the ESC poll external ADCs and stepper controllers without a host processor
- Device-emulation and external-CPU operating modes support both stand-alone and processor-hosted designs
- -40°C to +125°C junction rating suits demanding industrial EtherCAT node deployments
