4.4.1.3
Open-load detection in ON-state is implemented in the low-side switches of the bridge
outputs: When the current through the low side transistor is lower than the reference
current
according open-load diagnosis bit is set. The output transistor, however, remains ON.
The open load error bit is latched and can be reset by the SPI status register reset or by
a power-on reset.
As an example, if a motor is connected between outputs OUT 1 and OUT 2 with a broken
wire as shown in
