Overcurrent detection
When the current in any of the power MOSFETs exceeds a programmed overcurrent
threshold, STATUS register OCD flag is forced low until the overcurrent event is expired and
a GetStatus command is sent to the IC (see paragraphs 9.1.22: STATUS and 9.1.18:
STALL_TH). Overcurrent event expires when all the power MOSFET currents fall below the
programmed overcurrent threshold.
The overcurrent threshold can be programmed through the OCD_TH register in one of 16
available values ranging from 375 mA to 6 A with steps of 375 mA (see Table 9, paragraph
Through the CONFIG register OC_SD bit it is possible to set if an overcurrent event causes
or not bridges turn-off (switch to High Z state); the OCD flag in the STATUS register is raised
anyway (see Table 17, paragraphs 9.1.22: STATUS).
6.10
Undervoltage lock-out (UVLO)
The L6470 provides a motor supply UVLO protection. When the motor supply voltage falls
below the VSthOff threshold, STATUS register UVLO flag is forced low. When a GetStatus
command is sent to the IC, the UVLO flag is released even if the UVLO condition is still
present (see paragraphs 9.1.22: STATUS and 9.2.18: GetStatus). Undervoltage condition
expires when the motor supply voltage exceeds the VSthOn voltage. When the device is in
undervoltage condition no motion command can be performed. UVLO flag is forced low by
logic reset even (power-up included) if no UVLO condition is present.
