製品の詳細
- 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
TMC428 is obsolete and not recommended for new designs.
