Advanced Motor Control

– One enhanced PWM (EPWM) module with 12-bit resolution and six outputs to control

either a BLDC motor with six half-bridges (B6 configuration) or a bipolar stepper

motor with four half-bridges. The module supports center- and edge-aligned mode

with automatic dead-time insertion.

– Three high-voltage Back Electromotive Force Comparators (BEMFC) are supporting

zero crossing detection for sensorless BLDC motor control with integrated virtual star

point reference. Furthermore, the three comparators can be used for closed-loop cur-

rent control with bipolar stepper motors or alternatively for BEMF voltage measure-

ments with stepper motor for commutation and / or stall detection.

– Integrated phase current measurement for bipolar stepper motor control with closed-

loop current control.

– Two 8-bit DACs used as reference for current limitation (CLDAC) for bipolar stepper

motors in closed-loop current control.

– One 12-bit ADC with HW trigger option:

linear temperature sensor + input for motor current sensing + inputs for stepper

motor stall detection + inputs for LIN Auto-Addressing (BSM).

– ADC reference: internal band-gap reference

– One integrated Programmable Gain Amplifier (PGA) as part of the ADC signal path.
