产品详情

Controls up to three 2-phase stepper motors
Serial 4-wire interface for µC with easy-to-use protocol
Configurable interface for SPITM motor drivers
Different types of SPITM stepper motor driver chips may be mixed within a single daisy chain
Communication on demand minimizes traffic to the SPITM stepper motor driver chain
Programmable SPITM data rates up to 1 Mbit/s
Wide range for clock frequency – can use CPU clock up to 16 MHz
Internal 24 bit wide position counters
Full step frequencies up to 20 kHz
Read-out facility for actual motion parameters (position, velocity, acceleration) and driver status

Individual micro step resolution of {64, 32, 16, 8, 4, 2, 1} micro steps via built-in sequencer
Programmable 6 bit micro step table with up to 64 entries for a quarter sine-wave period
Built-in ramp generators for autonomous positioning and speed control
On-the-fly change of target motion parameters (like position, velocity, acceleration)
Automatic acceleration dependent current control (power boost)
Low power operation: Only 1.25 mA @ 4 MHz (typ.)
Power down mode with transparent wake-up for normal operation
3.3V or 5V operation with CMOS / TTL compatible IOs (all inputs Schmitt-Trigger)
Available in ultra small 16 pin SSOP package and small 24 pin SOP package
