The L6460 main features
Four widely configurable full bridges:
●
●
Possible configurations for each bridge:
●
●
●
●
The L6460 is intended to maximize the use of its components, so when an internal circuit is
not in use it can be used for other applications.
Bridge 3, for example, can be used as a full bridge or to implement two switching regulators
with synchronous rectification. To obtain this flexibility the L6460 includes two independent
regulation loops that can be used for these regulators; when the bridge is used as a motor
driver, the two regulation loops can be redirected on general purpose I/Os to allow the
possibility of assembling a switching regulator by just adding an external FET.
