TMC4671-LA

Check Stock

The TMC4671-LA is a hardware Field-Oriented-Control engine that runs the full current, velocity and position control loop in silicon for BLDC, PMSM, stepper and voice-coil motors, freeing the host MCU from real-time control-loop work. Eight internal delta-sigma ADC channels digitize motor current and voltage directly, while flexible encoder and Hall feedback interfaces cover both digital and analog position sensors in the same 76-pin QFN.

Interface Features & Applications

Hardware FOC engine handles current, velocity and position control loops entirely in silicon, offloading the host MCU
8 internal delta-sigma ADC channels digitize motor current and voltage feedback without external ADCs
Supports digital encoder, analog interpolator encoder, and both digital/analog Hall feedback on the same silicon
25 kHz to 100 kHz fast PWM engine covers BLDC, PMSM, stepper and voice-coil motor types
Separate SPI application, UART debug, and SPI monitoring interfaces simplify commissioning and field diagnostics
-40°C to +125°C junction rating and dual-domain 3.3 V I/O / 1.8 V core supply suit compact servo drives

Why Buyers Source TMC4671-LA

TMC4671-LA is best treated as a sourcing-specific line item, not a generic replacement, because interface standard, isolation/protection level, package and operating grade can affect approval. 1305 pcs is listed as small-lot spot stock; LimChip should confirm live allocation, batch condition and lead time before purchase. Suited to buyers needing the exact TMC4671-LA ordering code — the hardware FOC servo controller with 8-channel ADC and encoder/Hall feedback in QFN76 (10.5×6.5 mm, 0.4 mm pitch) — rather than a generic part.

LimChip can confirm current price, date code, packing condition, lot traceability and shipment schedule for TMC4671-LA.

Interface IC Sourcing Checklist
