Function
SPI serial data input.
(Scan test input in test mode.)
Serial clock input of SPI interface.
(Scan test shift enable input in test mode.)
Digital and analog low power GND.
Chip select input for the SPI interface. (Active low.)
Power MOSFET enable input. All MOSFETs are switched off when
disabled. (Active low.)
System clock input for all internal operations. Tie low to use the
on-chip oscillator. A high signal disables the on-chip oscillator until
power down.
High-side supply voltage (motor supply voltage - 10V)
Motor supply voltage
Reserved. Do not connect.
stallGuard2 output. Signals a motor stall. (Active high.)
Input/output supply voltage VIO for all digital pins. Tie to digital
logic supply voltage. Operation is allowed in 3.3V and 5V systems.
Direction input. Sampled on an active edge of the STEP input to
determine stepping direction. Sampling a low increases the
microstep counter, while sampling a high decreases the counter. A
60-ns internal glitch filter rejects short pulses on this input.
Step input. Active edges can be rising or both rising and falling, as
controlled by the DEDGE mode bit. A 60-ns internal glitch filter
rejects short pulses on this input.
Test mode input. Puts IC into test mode. Tie to GND for normal
operation.
