28
Digital high side
outputs
2 short circuit protected active high outputs.
On / off control of the output only, no PWM voltage or current
regulation
Continuous sink current = 2A
Analogue supply
outputs
2 short circuit protected supply outputs.
Output1: 5V, 200mA max
Output2: 10V, 200mA max
Motor commutation
sensor inputs:
Quadrature AB encoder signal inputs provided for control of
induction motors
UVW digital position sensor or sin-cos analogue position sensor
or resolver inputs provided for control of permanent magnet
motors.
Resolver excitation
Two outputs, Exc+ and Exc-, provide a fixed 10kHz excitation
to a speed feedback resolver. Each output is 4V max pk-pk,
100mA, protected against short-circuit. Consult the ‘Resolver’
section in the System Design section of this document for
important information about resolver feedback.
