Switch between VBAT and VDD without removing VDD
My device has various connected sensors and peripherals. The device is intended to go to sleep for extended periods of time before waking up and taking measurements. Currently, the main VDD is a large external battery and VBAT is a coin cell used to ...
L6470 motor current vs MIN_SPEED
I use L6470 in my application at a certain running current. When I vary the speed the motor current remains more or less constant as expected. As soon as I change (actually increase) the MIN_SPEED value, the motor current changes (decreses). Anyone k...
Strong current peaks at the end of some 6-step phases
My team has designed a circuit board based on EVSPIN32F0251S1 and controlled by the "STSW-SPIN32F0251" firmware, using the configuration "6step_conf_sl_cm_spdlp.h". The motor is moving fine, but during some measurements, we found strong current peaks...
