OUT2 – HS UC

The open load detection monitors the load current in each activated output

stage. If the load current is below the under-current detection threshold for

at least 1 ms (tdOL) , the corresponding under-current bit UC is set. Due to

mechanical/electrical inertia of typical loads a short activation of the outputs

(e.g. 3ms) can be used to test the open load status without changing the

mechanical/electrical state of the loads.
