• Manufacturer Part Number: Q67000-A9103
• Description: 2.5-A High Performance Smart Power Stepper-Motor Driver with Diagnostic Interface
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

Bits 10, 11
With these bits it is possible to detect the status of the gate voltages of the lower output-
stage transistors T3 and T4. Bit 10: status for EN edge transition. Bit 11: whether the
lower transistor has at all been turned on.
Bit 12 indicates whether the nominal/actual comparator has switched. The comparator
switches when the output current is regulated.
Bits 13, 14, 15
These bits indicate the presence of overcurrent, undervoltage or overtemperature. A
fault is ORed and output direct by bit 0 on DI.
When the multiplexer is read out, bits 0 through 15 are output once non-inverted (Phase
= Low) and once inverted (Phase = High).

High for overtemperature/undervoltage/overcurrent
always High
High when sink transistor Q1 turned on
High when sink transistor Q2 turned on
High when source transistor Q1 turned on
High when source transistor Q2 turned on
momentary states for readout
bit 2 state for falling edge of Enable signal
bit 3 state for falling edge of Enable signal
bit 4 state for falling edge of Enable signal
bit 5 state for falling edge of Enable signal
represent status of outputs for negative change in edge of Enable signal
High if gate-source voltage of sink transistors is > 5 V at moment of readout
are set if event occurs during switching (Enable = High)
High if sink transistor V
High if actual current lower than nominal current
High if overcurrent detected on source transistors
High if undervoltage detected
High if thermal link tripped
