RFQ ListingPower Management ICs
A compact silent stepper driver built around StealthChop2 and StallGuard4, aimed at 3D-printer and office-automation axes that must run quietly yet detect stalls without end-stops. Its single-wire UART exposes advanced tuning, and the integrated pulse generator allows standalone motion off a small MCU.
